Running up to 30 hours on two standard AAA batteries, it suits venues that prefer field-swappable power over managed charging stations. The receiver pairs with any DLT 400 transceiver over an encrypted, license-free 2.4 GHz link.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe DLR 400 ALK receives digital spread-spectrum (DSS) audio from Digi-Wave DLT 400 transceivers in the 2.4 GHz ISM band, using a frequency-hopping algorithm to avoid interference from venue Wi-Fi and other RF traffic — with no FCC licensing or frequency coordination required. 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. It is compatible with both DLT 400 and DLT 300 transceivers.

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.

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.

built for the Digi-Wave DLT 400 transceiver, combining a unidirectional electret boom microphone with circumaural noise-reducing earphones. It is the headset of choice for simultaneous interpretation, plant tours, and two-way communication in high-noise environments where interpreters and tour guides need to hear program audio clearly while speaking. The package pairs the proven MIC 068 headset with the ADP 016 y-splitter adapter, allowing both the microphone and headphone connections to interface with a single DLT 400 transceiver.

The dual-muff design seals around both ears with a 20 dB noise reduction rating, so interpreters working from a booth or guides walking a factory floor can monitor the floor feed or interpretation channel without raising volume to unsafe levels. The unidirectional electret microphone element rejects off-axis sound, keeping the transmitted signal focused on the wearer's voice rather than machinery, HVAC, or crowd noise.\u003c\/p\u003e\n\u003cp\u003eElectrically, the microphone presents 1 kΩ impedance with -42 dB sensitivity and operates on 2–10 VDC bias supplied by the host transceiver. The headphone drivers offer 35 Ω impedance and a full 20 Hz – 20 kHz frequency response, giving wearers natural-sounding monitor audio for long sessions. Termination is via dual 3.5 mm stereo TRS plugs on a 39-inch cable, with the included ADP 016 y-splitter combining both connections into the single TRRS headset jack on the Digi-Wave DLT 400 transceiver. The headset weighs 0.75 lbs and is CE and RoHS compliant.\u003c\/p\u003e\n\u003cp\u003eFor AV integrators specifying Digi-Wave 400 Series systems for interpretation, intercom, or guided tour applications, the MIC 168 is the standard heavy-duty headset accessory for talker positions in loud spaces.

The low-profile 60mm diameter puck form factor makes it suited for conference tables, podiums, and interpretation booth surfaces where a discreet, cable-connected microphone input is required.

The electret capsule provides omnidirectional polar coverage with -40 dB sensitivity and 1500Ω output impedance, appropriate for close-field speech pickup in conference and interpretation settings. The 3.5mm TRRS plug connects directly to the DLT 400 TRRS microphone input, with a 39\" (99 cm) cord providing adequate reach from the transceiver to a tabletop placement. The black puck measures 60mm diameter x 16mm height—low enough to remain unobtrusive on a conference table surface. Bias power requirement of 1.0–10 VDC is supplied by the connected transceiver, requiring no external power. The MIC 449 is appropriate for language interpretation consoles, Digi-Wave conference system deployments, courtroom proceedings, and any application where a DLT 400 is used as a wireless transmitter

full-duplex wireless microphone transceiver built for real-time, two-way communication in professional AV environments. Operating in the license-free 2.4 GHz band, it transmits and receives simultaneously without external amplification, which makes it a practical two-way intercom microphone transceiver for language interpretation, guided tours, and team coordination. As part of the Digi-Wave 400 Series, the T410 integrates directly with existing 400 Series transceivers and receivers, so integrators can scale an installed system without changing platforms. The handheld form factor and USB-C charging keep deployment and event turnaround fast.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe DW T410 is the first portable, handheld transceiver in the Digi-Wave line to combine microphone input and full-duplex audio in a single unit, giving commercial AV teams a wireless intercom and interpretation tool that does not depend on a fixed base station. Because it operates in the 2.4 GHz band with a frequency-hopping algorithm, it resists interference in congested RF environments typical of conference centers and government facilities. Two advanced operating modes — Advanced Communication (ACM) and Advanced Interpretation (AIM) — let a system designer configure channels, subgroups, and leader\/guest roles to match the workflow of a broadcast crew, an interpretation booth, or a guided-tour group. A built-in menu and three access levels (Super Lock, Basic Lock, and Unlocked) allow AV managers to lock settings during device hand-offs while retaining full administrative control. The 3.5 mm TRS jack accepts Williams AV headphones, earphones, and neckloops, so the same unit supports both talk-and-listen operators and listen-only participants when paired with a \u003ca href=\"https:\/\/creationnetworks.net\/search?q=DLR%20400%20RCH\"\u003eDLR 400 RCH receiver\u003c\/a\u003e.
