Williams AV DWS COM 8 400 – 8-User Digi-Wave Wireless Intercom

Product Overview

The Williams AV DWS COM 8 400 is an eight-user Digi-Wave 400 wireless intercom system for production teams, training environments, and commercial facilities that need license-free, full-duplex communication. 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.

Product Description

The 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. If your deployment also calls for listen-only positions, add DLR 400 RCH receivers, or step up to the DWS COM 8 PRO 400, which adds a 12-bay drop-in charger and heavy-duty case for daily fleet operations.

System includes: (8) DLT 400 transceivers, (8) MIC 144 headset microphones, (8) DW ACC PAC4, (1) CCS 056 DW 11 system carry case, (1) CCS 061 GR grey silicone skin, (7) CCS 061 BK black silicone skins.

Frequently Asked Questions

What is the difference between the DWS COM 8 400 and the DWS COM 8 PRO 400?

Both systems provide eight DLT 400 transceivers with headset microphones. The PRO version adds the CHG 412 12-bay drop-in charger and the CCS 042 heavy-duty case, which suit daily-use fleets; the standard COM 8 400 charges units via the included accessory packs and USB-C.

Does this system require an FCC license to operate?

No. It operates in the license-free 2.4 GHz ISM band with frequency-hopping spread spectrum, so there is no spectrum licensing or coordination required at any deployment site.

How many people can talk at the same time?

Up to six participants can speak simultaneously in full duplex; remaining transceivers and any added Digi-Wave receivers monitor the conversation, so the listening pool can be much larger than eight.

Can the system be wired into a room audio system or mixing console?

Yes. Each DLT 400 provides USB-C line-level audio I/O, and the Williams AV DWD 401 Digi-Wave Connect breakout box converts that connection to balanced XLR for integration with a DSP, console, or installed sound system.

Is it compatible with Digi-Wave 300 Series equipment?

Yes, with limitations. The DLT 400 includes an 87-bit encryption mode that interoperates with DLT 300 and DLR 360 units, allowing mixed fleets during a phased migration to the 400 Series.

What warranty applies?

Williams AV provides a 2-year warranty against component failure and manufacturing defects, with 6 months of coverage on internal batteries.
