The package combines four IR E4 emitters and an IR A4 emitter array to flood expansive venues such as auditoriums and performing arts spaces with stable infrared coverage. Four WIR RX22-4N bodypack receivers, dual-bay chargers, earphones, and ADA signage are included, giving integrators a complete ADA-compliant assistive listening solution in a single SKU. For facilities that already run a Dante audio network, the SY22 D drops into the existing infrastructure without analog tie lines.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eAt the head end, the IR M1 D infrared modulator occupies a single rack unit and accepts audio over Dante or through two combination XLR\/quarter-inch TRS inputs that handle balanced or unbalanced line-level and microphone signals with selectable phantom power. DSP-based audio processing provides compression at 1:1, 1.5:1, or 2:1 along with high-pass and low-pass filtering, so speech intelligibility can be tuned to the room. Configuration is handled through an embedded web page, and an adjustable auto carrier shut-off conserves emitter life when no program audio is present.\u003c\/p\u003e\n\u003cp\u003eInfrared distribution is where this system configuration stands apart from smaller IR+ packages: four IR E4 emitters plus the IR A4 array connect back to the modulator over standard Cat5e cable, which carries +48 VDC power, RS-485 control, and the baseband IR signal on a single run per emitter. Each IR E4 covers up to 18,000 square feet in single-channel mode, so the four-emitter complement is sized for large halls, balconied auditoriums, and venues with irregular sight lines. Because infrared light does not pass through walls, adjacent rooms can run independent systems without interference, and program audio stays inside the room.\u003c\/p\u003e\n\u003cp\u003eOn the listening side, the four-channel WIR RX22-4N bodypack receivers run up to 60 hours on alkaline AA batteries and ship with lanyards and EAR 022 earphones; two BAT KT6 dual-bay charger kits keep rechargeable batteries in rotation.

Each IR A4 connects up to four IR E4 infrared emitters, and a fully expanded system supports up to 16 emitters from a single IR M1 control center. AV integrators specify the IR A4 for large venues — auditoriums, convention spaces, and houses of worship — where distributed emitter placement is required to maintain line-of-sight coverage across balconies, wings, and divided seating areas.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe IR+ platform uses a distributed emitter array architecture: rather than relying on one high-power transmitter panel, coverage is built from compact IR E4 emitters placed where listeners need them. The IR A4 extends that architecture. It accepts the feed from the IR M1 modulator over CAT5e and fans it out to as many as four IR E4 emitters, with each CAT5e leg carrying 48 VDC power, RS-485 communication, and the baseband infrared signal. Maximum cable length is 328 feet (100 meters), giving designers substantial flexibility in routing emitter runs through large commercial spaces.\u003c\/p\u003e\n\u003cp\u003eBecause the IR A4 is a passive part of the signal and power distribution chain, deployment is straightforward: home-run the array to the modulator, then branch CAT5e to each emitter location. Note that the IR A4 is not a standalone product — it requires an IR M1 modulator and at least one IR E4 emitter to function — and it is not plenum-rated, so installations in plenum spaces require a plenum enclosure. The array dissipates only 1 W of heat, simplifying enclosure planning.

The compact emitter connects to the IR M1 modulator over a single CAT5e cable that supplies power, control, and audio signal, eliminating the need for an electrical outlet at the mounting location. AV integrators deploy IR E4 emitters individually or in distributed arrays to deliver ADA-compliant infrared assistive listening across auditoriums, sanctuaries, courtrooms, and large meeting rooms.

Up to four emitters connect directly to the IR M1 modulator's RJ-45 ports, and systems can scale to 16 emitters with IR A4 emitter arrays.

The cable delivers 48 VDC power from the modulator, RS-485 communication, and the baseband infrared signal, so the emitter mounts anywhere structured cabling can reach. The included BKT 024 bracket supports wall or ceiling mounting, and at 0.8 pounds the unit places minimal demand on mounting surfaces. Because infrared light does not pass through walls, IR E4-based systems keep audio confidential within the room and allow adjacent spaces to run independent channels without interference.

Housed in a single rack unit, the modulator includes a two-channel Dante input plus analog XLR\/TRS inputs, and drives up to four IR E4 infrared emitters over CAT5e cabling. AV integrators use the IR M1 D as the head end of ADA-compliant infrared assistive listening systems in auditoriums, courtrooms, and houses of worship.

As an infrared modulator, it generates FM wideband carriers on selectable frequencies (2.3\/2.8 or 3.3\/3.8 MHz) for transmission through connected emitters — the right choice where audio must stay inside the room, since infrared cannot penetrate walls. As a Wi-Fi audio server, it streams the same program audio over a multicast-enabled network to the free Williams AV WaveCAST app on listeners' iOS and Android smartphones, extending coverage to users who prefer their own devices.\u003c\/p\u003e\n\u003cp\u003eAudio enters the unit through the two-channel Dante network input or two combination XLR\/1\/4-inch TRS jacks accepting balanced or unbalanced line-level or microphone signals with selectable phantom power.

Four RJ-45 emitter ports each deliver 48 VDC power, RS-485 communication, and baseband signal over a single CAT5e run, supporting distributed emitter placement across wings, balconies, or obstructed areas — each connected IR E4 covers up to 18,000 square feet.

The IR+ Combo package pairs the IR M1 infrared modulator and Wi-Fi server with one IR E4 infrared emitter and an IDP 008 ADA wall plaque. The emitter covers up to 18,000 square feet in single-channel mode, making the system a practical fit for auditoriums, sanctuaries, council chambers, and large training rooms.

Two combination XLR\/1\/4-inch TRS inputs accept balanced or unbalanced line-level feeds from a mixer or DSP, or microphone-level sources with selectable phantom power. Onboard DSP processing offers selectable compression ratios and high-pass\/low-pass filtering to maximize speech intelligibility, while a 400 Hz internal test tone, an IR test LED, and dual front-panel headphone jacks make commissioning and verification straightforward for the installing technician.\u003c\/p\u003e\n\u003cp\u003eThe included IR E4 emitter mounts on a wall or ceiling and connects to the modulator over a single CAT5e cable that carries 48 VDC power, RS-485 communication, and the baseband infrared signal — no electrical outlet is needed at the emitter position. The IR M1 also streams audio over Wi-Fi: connected to a multicast-capable network, it serves the program feed to the free Williams AV WaveCAST app on listeners' iOS and Android devices. Configuration, including the adjustable auto carrier shut-off, is handled through an embedded web interface.

The IR+ Combo includes the IR M1 D infrared modulator and Wi-Fi server with a two-channel Dante input, one IR E4 infrared emitter, and an IDP 008 ADA wall plaque. The emitter covers up to 18,000 square feet in single-channel mode, suiting auditoriums, courtrooms, sanctuaries, and large meeting spaces.

For integrators working on Dante-based projects, the assistive listening feed routes directly from the house DSP over the existing network with no analog tie lines. DSP-based processing in the modulator provides selectable compression ratios and high-pass\/low-pass filtering, while a 400 Hz internal test tone and dual front-panel headphone jacks support fast commissioning and channel monitoring.\u003c\/p\u003e\n\u003cp\u003eThe included IR E4 emitter connects over a single CAT5e cable that delivers 48 VDC power, RS-485 communication, and the baseband infrared signal from one of the modulator's four RJ-45 ports — no power outlet is required at the emitter location. The IR M1 D also acts as a Wi-Fi audio server, streaming program audio to the free Williams AV WaveCAST app on listeners' iOS and Android devices when connected to a multicast-enabled network. All settings, including the adjustable auto carrier shut-off, are managed through an embedded web interface.

The IR+ Flex package combines the IR M1 infrared modulator and Wi-Fi server with two IR E4 infrared emitters, an MLB 003 metal linking bar, and an IDP 008 ADA wall plaque. Each emitter covers up to 18,000 square feet in single-channel mode, so the two-emitter configuration handles auditoriums, sanctuaries, and multi-zone rooms with balconies or wings.

DSP-based processing offers selectable compression ratios and high-pass\/low-pass filtering, while a built-in 400 Hz test tone and dual front-panel headphone jacks streamline commissioning and channel monitoring. The IR M1 doubles as a Wi-Fi audio server: connect it to a multicast-capable network and listeners can stream the program feed to their own smartphones through the free Williams AV WaveCAST app, supplementing the dedicated infrared receivers.\u003c\/p\u003e\n\u003cp\u003eThe two included IR E4 emitters each connect to the modulator over a single CAT5e cable that carries 48 VDC power, RS-485 communication, and the baseband infrared signal — no power outlets are needed at the emitter mounting locations. Mount both emitters together on the included MLB 003 linking bar for a concentrated array, or split them across the room to reach obscured seating areas. All configuration is available remotely through the modulator's embedded web interface, including an adjustable auto carrier shut-off that powers down the IR carrier when no audio is present.

This IR+ Flex package pairs the IR M1 D infrared modulator and Wi-Fi server with two IR E4 infrared emitters, an MLB 003 metal linking bar, and an IDP 008 ADA wall plaque. With each emitter covering up to 18,000 square feet in single-channel mode, the two-emitter configuration supports wide or irregular rooms, balconies, and wings. Dante audio networking lets integrators feed the system directly from an existing digital audio network without analog tie lines.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eAt the core of the IR ME2 D is the rack-mount IR M1 D control center, a single rack unit infrared modulator with built-in Dante input supporting two channels. In addition to Dante, the modulator accepts two analog sources through combination XLR\/1\/4-inch TRS jacks that handle balanced or unbalanced line-level signals or microphones with selectable phantom power, so it drops into virtually any commercial audio system. DSP-based audio processing provides selectable compression ratios and high-pass\/low-pass filtering, and a 400 Hz internal test tone simplifies commissioning. The unit also functions as a Wi-Fi audio server: connected to a multicast-enabled network, it streams program audio to listeners' smartphones via the free Williams AV WaveCAST app, giving venues both infrared and Wi-Fi delivery from one chassis.\u003c\/p\u003e\n\u003cp\u003eInfrared transmission is the preferred assistive listening technology where audio privacy matters, because the signal cannot pass through walls. The two included IR E4 emitters connect back to the modulator over single CAT5e runs that carry power, RS-485 control, and baseband signal — no local power at the emitter location. Emitters can be stacked on the included MLB 003 linking bar to form a high-output array, or distributed across the room to cover obstructed seating areas. Remote configuration is handled through the modulator's embedded web page, and dual front-panel headphone jacks allow channel monitoring during setup. The IDP 008 wall plaque documents assistive listening availability for ADA compliance.

The kit pairs the IR T1 two-channel infrared transmitter with one WIR RX22-4N four-channel bodypack receiver, folding headphones, and a flat-panel TV mounting bracket, covering up to 1,300 square feet. Setup is plug-and-play, and because infrared audio cannot leave the room, the system preserves privacy in sensitive environments.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe IR T1 transmitter combines the infrared modulator and emitter in one compact, mountable enclosure, reducing operating costs and eliminating the need for rack space. Connect any line-level stereo source to the 3.5mm input jack — the included WCA 124 adapter cable handles TVs with RCA stereo outputs — and the carriers enable automatically when audio is present. Power comes from the included TFP 055 power supply or directly from a TV's USB port via the included WCA 106 micro-USB cable, which keeps cabling minimal in patient rooms and resident apartments. Operating frequencies of 2.3 and 2.8 MHz minimize interference from high-efficiency lighting, and the channel automatically enters a power-save mode after 12 minutes without audio, cutting power consumption by 80 percent.\u003c\/p\u003e\u003cp\u003eThe included STD 008 flat-panel TV top shelf mounts the transmitter on a display without drilling, and the IR T1 also accepts any camera tripod with a 1\/4\"-20 thread. The WIR RX22-4N bodypack receiver offers four selectable channels, dual infrared detectors for strong sensitivity throughout the coverage area, and on\/off\/volume controls, running up to 60 hours on the included AA alkaline batteries. The HED 021 folding mono headphones provide comfortable, lightweight listening.

Audio connects through two Euroblock line inputs that accept balanced or unbalanced signal from a DSP, mixer, or amplifier, plus a 3.5mm microphone input with a dedicated gain knob and channel selector. A separate Euroblock control port supports integration with a room control system, so AV integrators can tie the transmitter into an existing automation processor. Back-panel green and yellow LEDs confirm power and signal presence at a glance, and a power-saving mode shuts off the IR carrier after 12 minutes without audio.\u003c\/p\u003e\u003cp\u003eThe five included WIR RX18 stethoset receivers use a low-mass, under-the-chin design that is easy to sanitize between users, an important consideration for assisted living and healthcare deployments.

It is the analog-input configuration of the IR+ Complete family, suited to houses of worship, lecture halls, and auditoriums fed from a conventional mixer or DSP line output.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe IR M1 infrared modulator anchors the system in a single rack unit. Two combination XLR\/quarter-inch TRS inputs accept balanced or unbalanced line-level or microphone signals with selectable phantom power, and the unit modulates two independent audio channels with carriers selectable between the 2.3\/2.8 and 3.3\/3.8 MHz pairs. That two-channel architecture supports dual-language services or simultaneous program and interpretation feeds from one head end. Facilities planning a move to networked audio can specify the \u003ca href=\"https:\/\/creationnetworks.net\/products\/williams-sound-ir-sy11-d-ir-complete-with-dante\"\u003eIR SY11 D\u003c\/a\u003e, which swaps in the Dante-equipped IR M1 D modulator.\u003c\/p\u003e\n\u003cp\u003eOnboard DSP applies selectable compression of 1:1, 1.5:1, or 2:1 plus high-pass and low-pass filtering, conditioning the signal for speech intelligibility. Configuration, monitoring, and the adjustable auto carrier shut-off all live in the modulator's embedded web page, and commissioning is straightforward with the 400 Hz internal test tone, dual IR test LED, and front-panel headphone jacks for both channels.\u003c\/p\u003e\n\u003cp\u003eThe two IR E4 emitters mount as a linked pair on the included MLB 003 metal linking bar with BKT 024 wall brackets. Each emitter receives +48 VDC power, RS-485 control, and the baseband infrared signal over a single Cat5e run from the modulator's RJ-45 ports, so installation amounts to two structured cabling pulls and a wall mount. Rated up to 18,000 square feet per emitter in single-channel mode, the pair covers large sanctuaries and assembly halls, with two spare modulator ports available for added emitters. Infrared cannot pass through walls, so adjacent rooms can run identical systems without interference and program audio remains inside the space.\u003c\/p\u003e\n\u003cp\u003eFour WIR RX22-4 four-channel bodypack receivers with lanyards serve listeners, paired with four HED 021 performance headphones and two NKL 001 neckloops for telecoil hearing aid users. Four pairs of rechargeable AA batteries and two CHG 3502 drop-in chargers keep the fleet powered, and the IDP 008 plaque documents assistive listening availability.

Two linked IR E4 emitters, four four-channel WIR RX22-4 bodypack receivers, headphones, neckloops, chargers, and ADA signage ship together, so an AV integrator can deliver compliant hearing assistance for an auditorium or worship space from a single part number.

DSP-based processing applies compression at 1:1, 1.5:1, or 2:1 and high-pass\/low-pass filtering tuned for speech intelligibility, and the embedded web page manages all settings remotely, including carrier selection between the 2.3\/2.8 and 3.3\/3.8 MHz pairs and the adjustable auto carrier shut-off timer.\u003c\/p\u003e\n\u003cp\u003eThe two IR E4 emitters mount as a pair on the included MLB 003 linking bar with BKT 024 wall brackets. Each connects to the modulator over one Cat5e cable carrying +48 VDC power, RS-485 communication, and the baseband infrared signal, which keeps installation to a pair of structured cabling runs. Rated at up to 18,000 square feet per emitter in single-channel mode, the linked pair covers large sanctuaries, lecture halls, and council chambers, and the modulator's four RJ-45 ports leave headroom to add emitters if coverage requirements grow. Infrared stays inside the room, so multi-room facilities avoid cross-talk entirely.\u003c\/p\u003e\n\u003cp\u003eThe receiver package is what earns the Complete name.

Infrared light does not pass through walls, which makes this large-area system a standing specification for courtrooms, hearing rooms, and confidential government spaces. The package combines the IR M1 modulator with two linked IR E4 emitters, five rechargeable IR RX20 stethoset receivers, two neckloops for hearing aid users, a five-bay charger, and ADA wall signage.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe system head end is the IR M1 infrared modulator, a single-rack-unit unit with two combination XLR\/quarter-inch TRS audio inputs that accept balanced or unbalanced line-level or microphone signals with selectable phantom power. Two independent audio channels can be modulated, with carrier frequencies selectable between the 2.3\/2.8 MHz and 3.3\/3.8 MHz pairs, supporting dual-language or program-plus-assistance configurations.

An embedded web page handles configuration, the adjustable auto carrier shut-off, and diagnostics, while a 400 Hz internal test tone and front-panel headphone jacks for both channels speed setup and troubleshooting at the rack.\u003c\/p\u003e\n\u003cp\u003eCoverage comes from two IR E4 emitters mounted together on the included MLB 003 metal linking bar with BKT 024 wall brackets. Each emitter connects to the modulator over a single Cat5e cable that delivers +48 VDC power, RS-485 communication, and the baseband infrared signal, so the emitter wall needs no electrical outlet. With each IR E4 rated up to 18,000 square feet in single-channel mode, the linked pair covers large courtrooms and assembly rooms from one position, and identical systems can run in adjacent rooms without any frequency coordination.\u003c\/p\u003e\n\u003cp\u003eListeners use the IR RX20 stethoset receiver, a 1.6-ounce under-chin unit with an internal LiPo battery rated for 8 hours per charge; all five recharge in the included CHG 520 five-bay charger.

Because infrared light cannot pass through walls, the transmitted program stays inside the room.

Rated at up to 18,000 square feet per emitter in single-channel mode, the linked pair covers substantial courtrooms and hearing rooms from one wall position.

It is the highest-coverage configuration in the IR+ family, specified for auditoriums, large houses of worship, and government assembly chambers where a single emitter cannot reach every seat. Everything required for an ADA-compliant infrared hearing assistance deployment ships in the box, including chargers, earphones, and compliance signage.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eSystem design starts at the rack: the IR M1 D is a single-rack-unit infrared modulator that takes program audio either from two Dante network channels or from a pair of combination XLR\/TRS connectors supporting balanced or unbalanced line-level and mic-level sources with selectable phantom power. For integrators working in networked AV environments, the Dante input means the assistive listening feed is just another route in Dante Controller rather than a dedicated analog run from the DSP.\u003c\/p\u003e\n\u003cp\u003eThe modulator's DSP stage offers three compression ratios and adjustable high-pass and low-pass filters to shape program audio for hearing-impaired listeners, and a 400 Hz internal test tone speeds commissioning. All settings, including selectable carrier frequencies of 2.3\/2.8 or 3.3\/3.8 MHz, are managed through the unit's embedded web page, so a technician can adjust the system from a laptop on the network without pulling the unit from the rack.\u003c\/p\u003e\n\u003cp\u003eCoverage comes from four IR E4 emitters and the IR A4 array. Each emitter home-runs to one of the modulator's four RJ-45 ports on a single Cat5e cable carrying +48 VDC power, RS-485 communication, and the baseband IR signal, which keeps electrical work at the emitter locations to zero. With each IR E4 rated at up to 18,000 square feet in single-channel mode, this four-emitter package handles deep rooms, wide fan-shaped seating, and under-balcony zones that block line of sight from a single transmitter position. Since IR energy is contained by the room's walls, neighboring spaces can operate their own systems on the same frequencies.\u003c\/p\u003e\n\u003cp\u003eListeners use the WIR RX22-4N bodypack receiver, a four-channel unit with a dual-lens detector, lanyard, and 3.5 mm output driving the included EAR 022 earphones or optional neckloops for hearing aid users.

The stethoset form factor is the defining choice here: under-chin receivers are easy to hand out, easy to sanitize, and familiar to patrons in theaters and worship venues. With a five-bay drop-in charger and ADA signage included, the system delivers a complete infrared hearing assistance package for commercial venues running Dante audio networks.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe rack-mounted IR M1 D modulator anchors the system in a single rack unit. Program audio arrives over two Dante network channels or through two combination XLR\/quarter-inch TRS inputs that accept balanced or unbalanced line-level or microphone signals with selectable phantom power. Onboard DSP provides selectable compression and high-pass\/low-pass filtering to keep speech intelligible for listeners with hearing loss, while an embedded web page exposes every setting for remote configuration and diagnostics.\u003c\/p\u003e\n\u003cp\u003eTwo IR E4 emitters and the IR A4 array distribute the infrared signal. Each connects to the modulator over a single Cat5e cable that delivers +48 VDC power, RS-485 communication, and the baseband signal, so emitter locations need no local power. An IR E4 covers up to 18,000 square feet in single-channel mode, giving the two-emitter-plus-array complement comfortable headroom in auditoriums, council chambers, and performance spaces. Because infrared cannot penetrate walls, the audio stays inside the room and adjacent venues can reuse the same carrier frequencies.\u003c\/p\u003e\n\u003cp\u003eThe IR RX20 stethoset receivers weigh 1.6 ounces, run roughly 8 hours per charge on their internal LiPo batteries, and drop into the included CHG 520 five-bay charger between events, eliminating disposable battery management. A three-position switch selects 2.3 MHz, 2.8 MHz, or stereo operation, and a 3.5 mm jack accepts external earphones or neckloops when needed.

Covering up to 1,300 square feet with the WIR RX22-4 receiver, the IR T1 suits small conference rooms, hospital rooms, assisted living facilities, and jury deliberation rooms. Its 2.3\/2.8 MHz operating frequencies minimize interference from high-efficiency lighting, and no FCC license or radio approval is required anywhere in the world.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe IR T1 is built for plug-and-play deployment: any line-level stereo source connects to the 3.5mm input jack, with channel 1 on the tip and channel 2 on the ring for one- or two-channel operation. The transmitter ships with the TFP 055 universal power supply, a 6-foot USB-to-micro-USB power cable, a 3.5mm stereo audio cable, and an RCA adapter cable for televisions — and because the unit draws just 5 VDC at 0.2 A, it can be powered directly from a TV's USB port, keeping installations clean in patient rooms and residential units.\u003c\/p\u003e\u003cp\u003eHigh-efficiency LEDs display power status and audio presence per channel. When no audio is detected on a channel for 12 minutes, the carrier shuts off automatically to save power, then re-enables the moment audio returns. The chassis includes a 1\/4\"-20 threaded mount compatible with any camera tripod, and optional accessories include the STD 008 TV-top shelf and the BKT 024 omnidirectional wall\/ceiling mount, giving AV integrators several placement options for line-of-sight coverage.\u003c\/p\u003e\u003cp\u003ePair the IR T1 with the \u003ca href=\"https:\/\/creationnetworks.net\/products\/williams-sound-wir-rx22-4n-4-channel-infrared-receiver\"\u003eWIR RX22-4N bodypack receiver\u003c\/a\u003e or the \u003ca href=\"https:\/\/creationnetworks.net\/products\/williams-sound-ir-rx20-infrared-receiver\"\u003eIR RX20 stethoset receiver\u003c\/a\u003e, both compatible with its 2.3\/2.8 MHz carriers.

Covering up to 18,000 square feet in single-channel mode — 50 percent more than the previous WIR TX75 — the IR T2 combines the modulator and emitter in one compact, wall- or ceiling-mountable enclosure with no rack space required. Selectable 2.3, 2.8, 3.3, and 3.8 MHz transmission frequencies and RS-232 control readiness make it a straightforward specification for installed commercial AV systems.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eWith a significantly wider coverage pattern and more output power than its predecessor, a single IR T2 covers most medium-area venues without the added expense of secondary emitter units. Audio connects through two Euroblock line inputs that accept balanced or unbalanced signal from a DSP, mixer, or amplifier, while a 3.5mm microphone input with a dedicated gain knob and channel selection switch supports standalone operation. Back-panel LEDs indicate power status and audio presence per channel, and a power-saving mode shuts off the IR carrier after 12 minutes without audio.\u003c\/p\u003e\u003cp\u003eFor managed AV environments, the IR T2 can be controlled remotely via RS-232 commands: powering the unit on and off, remotely setting the IR frequency pair (2.3\/2.8 or 3.3\/3.8 MHz), muting outgoing audio without powering down, switching the back-panel LEDs, and querying the unit for troubleshooting. The full command set is published in the IR T2 Programmer's Guide, making integration with room control processors straightforward. The transmitter ships with the BKT 024 wall\/ceiling mounting bracket and the TFP 057 international power supply with line cord, and it is compatible with WIR RX22-4, WIR RX18, and IR R1 receivers.\u003c\/p\u003e\u003cp\u003ePair the IR T2 with the \u003ca href=\"https:\/\/creationnetworks.net\/products\/williams-sound-wir-rx22-4n-4-channel-infrared-receiver\"\u003eWIR RX22-4N four-channel receiver\u003c\/a\u003e for bodypack listening, or see complete pre-built systems and accessories in the \u003ca href=\"https:\/\/creationnetworks.net\/collections\/williams-av\"\u003eWilliams AV collection\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e18,000 ft² Coverage\u003c\/strong\u003e — Single-channel mode with the RX22-4 receiver covers up to 18,000 square feet, 50 percent more than the WIR TX75 it replaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-in-One Enclosure\u003c\/strong\u003e — Modulator and emitter combine in one compact unit, eliminating rack space and simplifying mounting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRS-232 Control Ready\u003c\/strong\u003e — Remote commands handle power, frequency selection, audio mute, LED control, and troubleshooting from a room control system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour Selectable Frequencies\u003c\/strong\u003e — 2.3, 2.8, 3.3, and 3.8 MHz carriers support multi-channel operation for interpretation and avoid lighting interference.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional Audio Inputs\u003c\/strong\u003e — Two Euroblock line inputs accept balanced or unbalanced signal;

It ships with the WLC 004 line cord and inserts PoE power onto a standard Ethernet run, eliminating the need for an AC outlet at the transmitter's mounting location. Integrators specify the POE 001 when transmitters are ceiling- or wall-mounted away from convenient mains power.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eInfrared assistive listening transmitters perform best when mounted high with clear line of sight to the seating area — exactly where AC outlets rarely exist. The POE 001 solves this by injecting power onto the Ethernet cable already being run to the transmitter, so a single category cable delivers both power and connectivity to the device location. The injector sits at the head-end near the rack or network closet, plugs into mains via the included WLC 004 line cord, and passes PoE down the line to the remote transmitter. In IR T2 installations, the POE 001 is used together with the POE KT2 wiring kit, which breaks out power plus balanced or unbalanced line-level audio or RS-232 control at the transmitter end. This approach reduces electrician involvement, keeps plenum spaces free of AC wiring, and simplifies retrofit projects in finished ceilings.

At its core is the IR T3 medium-area infrared transmitter, which broadcasts on up to two channels (2.3\/2.8 MHz or 3.3\/3.8 MHz) for dual-language interpretation or a single assistive-listening feed. The system includes two WIR RX22-4N four-channel infrared receivers, headphones, a neckloop for telecoil users, a two-bay charger, rechargeable batteries, and a remote power kit for the emitter. Infrared coverage reaches up to 32,000 ft2 single-channel with the included receivers when emitters are placed for line-of-sight. Power over Ethernet and a universal 48 VDC supply give installers flexible cabling, and RS-232 control supports integration with third-party AV control systems.

As the core of a medium-area infrared assistive listening system, it broadcasts audio on up to two channels within a single room, making it well suited to courtrooms, boardrooms, and government spaces where signal must not pass through walls.

Because infrared light does not travel through walls, it is the preferred assistive listening technology for courtrooms, sensitive government meeting spaces, and multi-room facilities where channel privacy and RF containment matter. The transmitter operates in two-channel mode on 2.3 and 2.8 MHz (or 3.3 and 3.8 MHz) or in single-channel mode, allowing designers to deliver dual-language interpretation or a single assistive-listening feed. Coverage reaches up to 32,000 ft2 with a WIR RX22-4 receiver in single-channel mode when paired with the appropriate infrared emitters. Each channel provides a line-level Phoenix-style input with an audio-level LED, plus a 3.5 mm microphone input with gain control. A universal 48 VDC power supply (100-240 VAC, 18 W) and optional PoE support give integrators flexible power and cabling options, and RS-232 monitoring supports third-party control systems.
