Onboard DSP provides selectable compression (1:1, 1.5:1, or 2:1) and adjustable high-pass and low-pass filtering, shaping the signal for maximum speech intelligibility. Configuration is handled on the 3.12-inch OLED front-panel display or remotely through the transmitter's hosted web page, and the unit can be managed by third-party room control systems over its RJ-45 Ethernet connection.\u003c\/p\u003e\u003cp\u003eOn the listening side, each of the 24 PPA R38N receivers offers a 1-inch OLED display, menu-based selection across 17 wideband FM channels (72.1–75.9 MHz), and channel lock to prevent accidental retuning. Receivers run up to 50 hours on AA alkaline cells or 32 hours on the included NiMH rechargeable batteries, which charge in the two CHG 3512 12-bay drop-in chargers supplied with the system. Twenty-four EAR 022 surround earphones and six NKL 001 neckloops accommodate listeners with and without telecoil hearing aids, while the ANT 005 remote coaxial antenna extends FM coverage up to 1,000 feet.

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. The included IDP 008 wall plaque documents assistive listening availability for ADA compliance.

The FM+ T55 transmitter broadcasts on the 72 MHz FM band for the twelve included PPA R37N body-pack receivers while simultaneously streaming the same audio over the venue's Wi-Fi network for smartphone listeners. For facilities replacing aging FM 457 hardware or adding hearing assistance to a sanctuary, theater, or hearing room, this package delivers transmitter, receivers, earphones, neckloops, and ADA signage in one order.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe T55 transmitter occupies half a rack space and replaced the earlier T45 with substantially more capability: DSP audio processing with selectable compression and filtering, an OLED display for menu-driven setup, a hosted web page for remote configuration, and Telnet control over Ethernet for tie-in to room control systems. Audio sources connect through a combination XLR\/1\/4-inch input supporting balanced or unbalanced microphone or line-level signals with selectable phantom power — typically a spare DSP or mixer output in a commercial installation. Each of the twelve PPA R37N receivers offers seek-button access to 17 wideband channels between 72.1 and 75.9 MHz, channel lock to hold the house frequency, and a 3.5 mm output that drives the included EAR 022 surround earphones or the three NKL 001 neckloops supplied for telecoil hearing aid users. Receivers run approximately 50 hours on the included AA alkaline batteries and accept NiMH rechargeables with optional drop-in chargers. Because the FM broadcast supports unlimited listeners, the system scales simply by adding receivers — there is no license, channel pairing, or head-end change involved. This standard package leaves antenna selection and rack mounting to the integrator; FCC rules require professional installation with an approved FCC 15.203-compliant antenna such as the ANT 005.

As the successor to the legacy FM 457 systems, the FM+ platform broadcasts over FM and the venue Wi-Fi network from a single half-rack chassis, giving courtrooms, council chambers, theaters, and training facilities an ADA-compliant assistive listening solution that drops cleanly into a networked AV design.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eWhere most assistive listening transmitters terminate an analog feed, the T55 D in this package takes its program audio straight off the Dante network — a meaningful simplification in installations already running a Dante-enabled DSP, since the assistive listening rack needs only a network drop. An analog combination XLR\/1\/4-inch input remains available for balanced mic or line-level sources with selectable phantom power, so the transmitter works in hybrid signal chains as well. Internal DSP applies selectable compression and high-pass\/low-pass filtering, shaping the broadcast for maximum speech clarity. Operators configure the unit from its OLED front panel or the hosted web page, and integrators can drive it from third-party control systems via Telnet over the rear Ethernet port. The 12 included R37 receivers seek across 17 wideband channels between 72.1 and 75.9 MHz, and the package supplies everything needed to manage them day to day: a CHG 3512 12-bay drop-in charger, 12 sets of AA NiMH rechargeable batteries, surround earphones for each receiver, and three NKL 001 neckloops for telecoil hearing aid users. The ANT 005 remote coaxial antenna extends range up to 1,000 feet, the RPK 005 kit mounts the transmitter in a 19-inch rack, and the IDP 008 plaque posts ADA hearing assistance signage at the door. The FCC requires professional installation with an approved antenna, and Wi-Fi streaming uses the venue's existing wireless network.

It delivers assistive listening audio directly to T-coil hearing aids and cochlear implants — no receiver handout required — covering up to 30,000 sq ft with perimeter loops or supporting dual-amp and phased-array hearing loop installations. The system ships with loop wire, body-pack receivers, a charger kit, warning tape, and ADA signage for a full commercial deployment.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe DL207 NET amplifier at the heart of this system provides two independent 9.5 A loop outputs, making it the right platform for dual-amp designs and phased-array layouts that maintain even field strength in steel-structure buildings and adjacent-room installations. Onboard DSP includes parametric equalization, compression, metal loss compensation, AGC, high\/low-pass filters, and adjustable audio delay, while built-in calibration tools — a test tone generator with pink noise and loop current matching — streamline commissioning to the IEC 60118-4 field strength standard.\u003c\/p\u003e\n\u003cp\u003eThis \"D\" model adds a dedicated Dante input (44.1\/48 kHz, 24-bit) alongside balanced mic\/line, line-level, and 25\/70\/100 V speaker-level inputs, so the amplifier accepts audio from networked AV systems, mixing consoles, or distributed paging systems without converters. Configuration and calibration are handled locally from the front-panel LCD or over the network with the DigiLoop PC app via Ethernet, and a loop fault relay provides supervision for integration with monitoring systems. The 1 RU rack-mount chassis drops into standard equipment racks.\u003c\/p\u003e\n\u003cp\u003eThe system includes 500 ft of flat copper loop wire, warning tape, two PLR BP1 body-pack loop receivers with earbuds and a drop-in charger kit for guests without T-coil hearing aids, and a T-coil ADA wall plaque.

Built for ADA compliance in auditoriums, performing arts centers, and large houses of worship, it broadcasts the same program audio simultaneously over FM (72.1–75.9 MHz) and Wi-Fi, so attendees can listen on a dedicated FM receiver or their own smartphone via the WaveCAST app. The Dante input lets integrators pull audio directly from a networked audio system without analog conversion, making this the top-tier FM 558 package for modern AV-over-IP installations.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eAt the heart of the system is the FM+ T55C D transmitter, a half-rack, 1RU device that transmits dual FM and Wi-Fi audio from a single chassis.

DSP-based audio processing with selectable compression and high-pass\/low-pass filtering keeps speech intelligible for hearing-impaired listeners. A 3.12-inch OLED display and a hosted web page provide local and remote configuration, and the transmitter integrates with third-party room control systems for managed operation.\u003c\/p\u003e\u003cp\u003eThe 24 included PPA R38N body-pack receivers each feature a 1-inch OLED screen, menu-based access to all 17 wideband channels, channel lock, and up to 50 hours of runtime on alkaline batteries or 32 hours on the included NiMH rechargeables. Two CHG 3512 12-bay drop-in chargers keep the entire receiver fleet charged and staged, and six NKL 001 neckloops serve listeners with telecoil-equipped hearing aids. The PRO accessory kit rounds out the deployment with 24 EAR 022 surround earphones, an ANT 005 remote coaxial antenna for up to 1,000 feet of FM coverage, an IDP 008 ADA wall plaque, and an RPK 005 rack panel kit for mounting the transmitter in a standard 19-inch equipment rack.

The included AC CHG406 6-bay charger keeps the entire receiver fleet charged and organized at a welcome desk or AV closet, while two NKL 008 neckloops serve telecoil hearing aid users and six HED 024 folding headphones cover everyone else.

Four detachable 5 dBi omni-directional antennas provide coverage for typical assembly spaces, and four 10\/100\/1000M LAN ports plus a gigabit WAN port connect the WaveCAST transmitter, control network, and upstream infrastructure. WPA\/WPA2-PSK and AES security keep the audio network protected.\u003c\/p\u003e\n\u003cp\u003eIn a typical deployment, the WaveCAST transmitter connects to a LAN port via CAT 5e, the access point broadcasts the listening SSID, and guests join with WAV Pro receivers or the WaveCAST app on their phones.

The encrypted link keeps interpreted and assistive audio private, a relevant consideration for courtrooms, government briefings, and corporate sessions. At 1.7 ounces without batteries, the compact ABS housing carries an LCD showing battery level, signal strength, and group\/channel number, so staff can verify a unit's status before handing it to a guest. The 3.5 mm TRRS jack delivers mono output to headphones, earphones, or a telecoil neckloop, supporting hearing assistance and ADA compliance programs alongside interpretation duty — the Digi-Wave platform carries one floor language plus up to 14 interpreted languages. Because the DLR 400 ALK runs on two AAA alkaline batteries, venues can swap power in seconds mid-event and avoid investing in charging infrastructure, which is practical for occasional-use receiver pools and rental inventories.

Its internal lithium polymer battery delivers up to 32 hours per charge, and the receiver pairs with any DLT 400 transceiver over an encrypted, license-free 2.4 GHz link. For venues fielding dozens of receivers, drop-in charging via the CHG 412 keeps the fleet ready without battery swaps.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe DLR 400 RCH receives digital spread-spectrum (DSS) audio from Digi-Wave DLT 400 transceivers, with frequency hopping across 2402–2476 MHz to avoid interference from venue Wi-Fi and other 2.4 GHz traffic. Audio is protected by 87-bit plus 128-bit encryption with PIN support, which matters for courtroom interpretation, government briefings, and corporate events where content must stay private. Typical deployments include language interpretation — the Digi-Wave platform carries one floor language plus up to 14 interpreted languages — guided facility tours, hearing assistance for ADA compliance programs, and listen-only positions on a production intercom. The receiver matches the DLT 400 form factor at 3.3 ounces with an OLED status display, and its 3.5 mm TRRS headphone jack drives headphones, earphones, or a neckloop for hearing aid telecoil users. A USB-C port provides adjustable line-level audio output for feeding recorded archives or overflow sound systems, and doubles as the charging connector alongside contacts for the CHG 412 12-bay drop-in charger. With up to 32 hours of listening per five-hour charge and an auto-sleep mode that conserves power when no RF signal is present, the DLR 400 RCH suits venues that issue receivers daily.

It converts line-level audio to and from a DLT 400 transceiver via USB-C, letting integrators feed a mixing console, DSP, or room sound system into the wireless intercom or interpretation network — and pull Digi-Wave audio back out for recording or reinforcement. A power supply, USB-C cable, and BKT 040 mounting bracket are included for permanent installation.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eIn many Digi-Wave deployments, the wireless system needs to exchange audio with the rest of the AV installation: an interpreter booth feed from the house console, program audio into the interpretation channels, or intercom audio routed to a recording or overflow system. The DWD 401 handles this interface. Its 3-pin female XLR line input accepts audio from a console or DSP output and sends it to a connected DLT 400 transceiver for wireless distribution, while the 3-pin male XLR output delivers received Digi-Wave audio at line level to downstream equipment. The transceiver connects over a single USB 3.1 C cable (included), which carries the adjustable line-level audio path the DLT 400 already provides. The compact chassis — about 5.4 inches tall and under half a pound — mounts with the included BKT 040 bracket, so it installs cleanly behind a lectern, in an interpreter booth, at a rack shelf, or beside a credenza-mounted transceiver. Power comes from the included 5 VDC supply.

All four DLT 400 transceivers transmit simultaneously, so the team converses naturally without push-to-talk turn-taking. The kit includes headset microphones, charging accessories, identification skins, and a carry case, making it a complete entry point into the Digi-Wave 400 platform.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe DWS COM 4 400 packages four DLT 400 transceivers with four MIC 144 headset microphones, four DW ACC PAC4 charging accessory packs, a CCS 029 DW carry case, and color-coded silicone skins (one grey, three black) for quick role identification. The DLT 400 is a digital spread-spectrum (DSS) transceiver in the 2.4 GHz ISM band whose frequency-hopping algorithm (2402–2476 MHz FHSS) avoids interference from venue Wi-Fi and other RF traffic, while 87-bit plus 128-bit encryption with PIN protection keeps conversations confidential in courtrooms, government spaces, and corporate facilities. Full-duplex operation makes the system a cost-effective alternative to licensed two-way radios, with no FCC licensing or frequency coordination required at any site. Each transceiver provides up to 16 hours of talk time per charge from its internal lithium polymer battery and operates at ranges up to 900 feet depending on conditions. Because the Digi-Wave platform is multi-mode, the same four units can be reconfigured for language interpretation (one floor language plus up to 14 interpreted languages), guided tours with or without audience talkback, or hearing assistance. The system scales easily: add more DLT 400 transceivers for talkers — up to six simultaneous — or \u003ca href=\"https:\/\/creationnetworks.net\/products\/williams-sound-dlr-400-rch-digi-wave-400-receiver-rechargable\"\u003eDLR 400 RCH receivers\u003c\/a\u003e for listen-only participants.

Up to six users can speak at the same time while others listen, with no base station or frequency licensing required. The system ships as a complete kit — eight DLT 400 transceivers, headset microphones, silicone skins, and a transit case — ready for deployment by AV integrators or facilities staff.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe DWS COM 8 400 builds an eight-position wireless intercom around the DLT 400 transceiver, a digital spread-spectrum (DSS) device operating in the 2.4 GHz ISM band. Its frequency-hopping algorithm (2402–2476 MHz FHSS) avoids interference from Wi-Fi and other RF traffic common in commercial venues, while 87-bit plus 128-bit encryption with PIN protection keeps conversations secure in courtrooms, government spaces, and corporate facilities. Full-duplex operation means crews converse naturally rather than trading push-to-talk transmissions, making the system a cost-effective alternative to licensed two-way radio intercoms. Each transceiver runs up to 16 hours per charge on its internal lithium polymer battery and covers up to 900 feet depending on site conditions. The platform is multi-mode: the same eight units can be reconfigured for language interpretation supporting one floor language plus up to 14 interpreted languages, guided tours with or without audience talkback, or hearing assistance. The kit includes color-coded silicone skins so a director or lead position is identifiable at a glance, and a system carry case for transport between venues.

Up to six participants can talk simultaneously while additional users listen, with no base station, frequency coordination, or FCC licensing required. The PRO package adds a 12-bay drop-in charger and heavy-duty transit case, making it a complete deployable wireless intercom kit for events, courtrooms, training facilities, and live production.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe DWS COM 8 PRO 400 packages eight DLT 400 Digi-Wave transceivers with eight MIC 157 headset microphones, a CHG 412 12-bay charger, a CCS 042 heavy-duty system carry case, and color-coded silicone skins (seven grey, one black) so a lead operator can be identified at a glance. Each transceiver is a digital spread-spectrum (DSS) device operating in the 2.4 GHz ISM band with frequency-hopping (FHSS) to avoid interference from Wi-Fi and other RF sources in dense commercial environments. Communication is secured with 87-bit plus 128-bit encryption and an encryption PIN, which matters for courtrooms, government spaces, and corporate facilities where audio confidentiality is a requirement. Range is up to 900 feet depending on site conditions, and the internal lithium polymer battery delivers up to 16 hours of talk time per charge — enough for a full production day. Because the system is full duplex, conversation flows naturally without the push-to-talk turn-taking of conventional two-way radios, and the same hardware can be reconfigured for language interpretation (one floor language plus up to 14 interpreted languages) or guided tours with or without audience talkback. The CHG 412 charger returns the entire fleet to service overnight from a single rack shelf or table position, simplifying management for facilities staff.

It is an entry point into Digi-Wave tour guide audio for facility tours, training walkthroughs, and small-group communication, pairing a DLT 400 transceiver with 10 alkaline-powered DLR 400 ALK receivers.

Operating range extends up to 900 ft (274 m) depending on conditions.\u003c\/p\u003e\n\u003cp\u003eThe same hardware supports two-way intercom with up to six simultaneous talkers and an unlimited number of listeners, plus language interpretation with one floor language and up to 14 translated languages.

It is a complete, fully portable tour guide audio package for facility tours, training walkthroughs, and small-group listening where no installed AV infrastructure exists. A DLT 400 transceiver pairs with 11 DLR 400 RCH rechargeable receivers on the license-free 2.4 GHz band, and the included CHG 412 PRO 12-bay charger in a carry case recharges the entire fleet overnight.

Its frequency-hopping algorithm avoids interference from Wi-Fi and other 2.4 GHz traffic and provides a secure transmission path, with optional 87+128-bit encryption, an encryption PIN, and a settings lock for confidential environments. The guide transmits through the DLT 400 body-pack transceiver — via its built-in microphone or the included MIC 144 headset microphone — while listeners use DLR 400 RCH receivers with EAR 022 surround earphones.\u003c\/p\u003e\n\u003cp\u003eBecause every unit is rechargeable, daily operation is simple: drop transceiver and receivers into the CHG 412 PRO 12-bay charger after each session and they recharge in approximately five hours. The DLR 400 RCH delivers up to 32 hours of listening per charge and the DLT 400 up to 16 hours of talk time, comfortably covering multiple tour days between charges. Operating range reaches up to 900 ft (274 m) depending on conditions.\u003c\/p\u003e\n\u003cp\u003eThe same hardware also runs two-way intercom with up to six simultaneous talkers and an unlimited number of listeners, and language interpretation with one floor language plus up to 14 translated languages. That makes this kit equally useful for plant tours, museum programs, courtroom interpretation, team teaching, and staff communication in noisy commercial environments.

It pairs a DLT 400 transceiver with 20 alkaline-powered DLR 400 ALK receivers, making it a practical tour guide audio package for facilities that prefer field-replaceable AA batteries over charging stations. Operating license-free on the 2.4 GHz band with frequency hopping, the system deploys with no installation, base station, or rack-mount equipment. Everything ships in a CCS 056 26 hard carry case for transport between venues.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe Digi-Wave 400 Series is a digital spread-spectrum (DSS), simultaneous two-way wireless communication system. Its frequency-hopping algorithm avoids interference from Wi-Fi and other 2.4 GHz devices and provides a secure transmission path, with optional 87+128-bit encryption, an encryption PIN, and a settings lock. The guide speaks through the DLT 400 transceiver using its built-in microphone or the included MIC 144 headset microphone, and participants listen on DLR 400 ALK receivers fitted with EAR 022 surround earphones.\u003c\/p\u003e\n\u003cp\u003eThe ALK configuration is the right choice when charging infrastructure is impractical: each DLR 400 ALK runs up to 30 hours on two AAA alkaline batteries, so spare batteries in a pocket keep a tour program running all day with zero charger downtime. An LCD on each receiver shows battery level, signal strength, and group\/channel number for fast troubleshooting in the field. Operating range reaches up to 900 ft (274 m) depending on conditions.\u003c\/p\u003e\n\u003cp\u003eBeyond one-way tours, the same hardware supports two-way intercom with up to six simultaneous talkers and language interpretation with one floor language plus up to 14 translated languages, covering plant tours, museum and campus programs, courtrooms, and multilingual training.

It is a complete, fully portable tour guide audio package for facility tours, plant walkthroughs, and group listening applications where no installed infrastructure is available. The system pairs a DLT 400 transceiver with 23 DLR 400 RCH rechargeable receivers, operating on the license-free 2.4 GHz band with frequency-hopping to avoid interference. For AV integrators and facilities teams, it deploys in minutes with no base station, rack-mount components, or commissioning required.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe Digi-Wave 400 Series is a digital spread-spectrum (DSS), simultaneous two-way wireless communication system. Its frequency-hopping algorithm avoids interference from Wi-Fi and other 2.4 GHz devices and provides a secure transmission path, with optional 87+128-bit encryption, an encryption PIN, and a settings lock for environments where confidentiality matters. The guide transmits through the DLT 400 body-pack transceiver — using either its built-in microphone or the included MIC 144 headset microphone — while participants listen on DLR 400 RCH receivers with EAR 022 surround earphones.\u003c\/p\u003e\n\u003cp\u003eBeyond one-way guided tours, the same hardware supports two-way intercom operation with up to six simultaneous talkers and an unlimited number of listeners, and it functions as a language interpretation system supporting one floor language plus up to 14 translated languages. That flexibility makes it practical for manufacturing tours, museum and campus tours, courtroom interpretation, and staff communication in noisy environments. Coverage extends up to 900 ft (274 m) depending on site conditions.\u003c\/p\u003e\n\u003cp\u003eThis RCH configuration is the rechargeable package: receivers and the transceiver use internal lithium polymer batteries with smart charging, and two included CHG 412 PRO 12-bay drop-in chargers (in carry cases) recharge the full complement of units in about five hours — no battery swaps or consumable battery budget.

It is a one-to-one wireless listening system for assistive listening, interpretation, instruction, and staff support, where a talker wears the transceiver with the included lapel microphone and a listener receives clear digital audio through the EAR 041 earphone. Operating license-free on the 2.4 GHz band with frequency hopping, the kit needs no installation or base station and packs into the included carry case.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe Digi-Wave 400 Series is a digital spread-spectrum (DSS), simultaneous two-way wireless communication system. It makes hearing easier in everyday situations by reducing background noise and compensating for poor room acoustics or distance from the sound source — the core problem in classrooms, courtrooms, hospitals, and meeting spaces. The frequency-hopping algorithm avoids interference from Wi-Fi and other 2.4 GHz devices, and optional 87+128-bit encryption with a PIN code and settings lock secures the link where privacy matters.\u003c\/p\u003e\n\u003cp\u003eThe talker's DLT 400 transceiver accepts the included lapel microphone through its 3.5 mm mic input (or uses its built-in mic), while the listener's DLR 400 RCH receiver drives the included EAR 041 isolation earphone, a neckloop for hearing aid telecoil users, or other 3.5 mm listening accessories. Both units run on internal lithium polymer batteries — up to 16 hours of talk time on the transceiver and up to 32 hours of listening on the receiver — and recharge over USB-C in roughly five hours using the included power kit.\u003c\/p\u003e\n\u003cp\u003eBecause it is a platform rather than a closed pair, the system grows with your needs: add DLR 400 receivers for more listeners, or more DLT 400 transceivers for two-way intercom with up to six simultaneous talkers and interpretation supporting one floor language plus up to 14 translated languages.

The cable presents two female 3.5 mm inputs — one for the microphone and one for the headphone — combined into a single TRRS male connector that mates with the DLT 400's headset jack. This adapter is the required interface for deploying standard 2-plug headset accessories with the Digi-Wave 400 series transceiver.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe ADP 016 Y-splitter bridges the connection between two-plug headset microphones and the single TRRS combo jack on the Digi-Wave DLT 400 transceiver. Without this adapter, the MIC 068 and MIC 088 headset microphones — which use separate 3.5 mm mono plugs for audio output and microphone input — cannot be directly connected to the DLT 400. The Y-splitter combines both the microphone and earphone signal paths into the TRRS connector required by the transceiver's headset port. AV integrators deploying Digi-Wave 400 series systems for tour guide, simultaneous interpretation, or two-way communication applications who want to use the MIC 068 or MIC 088 headset accessory should include this adapter in their kit. The compact form factor adds minimal bulk to the transceiver setup. Note that this adapter is for the DLT 400 specifically; users of other Digi-Wave transceivers should verify headset compatibility before ordering.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTRRS Male Output\u003c\/strong\u003e — Single TRRS connector matches the headset jack on the Digi-Wave DLT 400 transceiver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Female 3.5 mm Inputs\u003c\/strong\u003e — Separate jacks for microphone and headphone signals from two-plug headset accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMIC 068 and MIC 088 Compatible\u003c\/strong\u003e — Required adapter for connecting these headset microphones to the DLT 400.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Build\u003c\/strong\u003e — Minimal added bulk to the transceiver and headset combination.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e90-Day Warranty\u003c\/strong\u003e — Standard Williams Sound accessory coverage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto\"\u003e\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse:collapse;width:100%;min-width:320px\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eADP 016\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector (Output)\u003c\/td\u003e\n\u003ctd\u003eTRRS male\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnectors (Input)\u003c\/td\u003e\n\u003ctd\u003e2x female 3.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Microphones\u003c\/td\u003e\n\u003ctd\u003eMIC 068, MIC 088\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Transceiver\u003c\/td\u003e\n\u003ctd\u003eDigi-Wave DLT 400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e90 Days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Williams AV","offers":[{"title":"Default Title","offer_id":43738851148012,"sku":"ADP 016","price":46.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/products\/williams-sound-adp-016-headset-y-splitter-creation-networks-54673.png?v=1757912406"},{"product_id":"williams-sound-bkt-040-digi-wave-400-series-bracket","title":"Williams AV BKT 040 – Digi-Wave 400 Series Mounting Bracket","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Williams AV BKT 040 is a mounting bracket for Digi-Wave 400 Series devices, designed to hold a DLT 400 transceiver or DLR 400 RCH receiver when used with the DWD 401 Digi-Wave audio interface.
