Williams AV MIC 157 – Single-Muff Headset Microphone, TRRS Plug
Product Overview
The Williams AV MIC 157 is a single-muff headset microphone with a TRRS 3.5mm plug, designed for use with Digi-Wave DLT 400 transceivers, the IC-2 interpreter console, and Digi-Wave 100/300 transceivers via the AC ADP3 adapter. It provides a hands-free microphone and single-ear monitoring solution for interpreters, tour guides, and presenters operating within the Williams AV Digi-Wave digital wireless system. The single-muff form factor is well-suited for environments where situational awareness in one ear is required.
Product Description
The MIC 157 fills a specific role in Digi-Wave system deployments where the operator needs to speak and monitor audio simultaneously while remaining aware of ambient sounds. The single-ear muff provides an earphone on one side and leaves the other ear open—a configuration preferred by interpreters, tour guides, and conference moderators. The TRRS 3.5mm plug connects directly to the DLT 400 transceiver’s TRRS input, enabling both microphone input and receiver audio output over a single connection. It is also compatible with the IC-2 interpreter console via the TRRS input and with Digi-Wave 100/300 series transceivers when used with the AC ADP3 adapter. This makes the MIC 157 a versatile accessory across multiple Williams AV Digi-Wave product generations. Ideal for language interpretation booths, guided museum tours, corporate event moderation, and courtroom communication systems.
