Product Overview

The Williams AV MIC 145 is a dual headset microphone with a TRRS 3.5mm plug, designed exclusively for use with the Williams AV Digi-Wave DLT 400 transceiver. The dual-ear design provides both microphone input and stereo audio monitoring, making it well-suited for interpreters and conference operators who require hands-free voice pickup and simultaneous audio monitoring in both ears. The noise-cancelling electret condenser capsule with gooseneck boom delivers clear speech pickup in professional AV environments.

Product Description

The MIC 145 is the dual-muff counterpart to the MIC 157 single-muff model, providing full bilateral audio monitoring for applications where both-ear coverage is required. Interpreters working in language interpretation booths, conference moderators, and AV operators who need consistent audio in both ears while transmitting will benefit from the MIC 145s dual-ear form factor. The electret condenser noise-cancelling element provides more than 60 dB signal-to-noise ratio at 1 kHz and a frequency response of 100 Hz to 10 kHz, appropriate for voice intelligibility in interpretation and conference settings. The gooseneck boom positions the capsule consistently relative to the talkers mouth. The TRRS 3.5mm plug connects directly to the DLT 400s single TRRS connector, carrying both microphone and headset audio over one plug. Headset impedance of 32 (stereo) is matched to the DLT 400s output stage. The MIC 145 is for use with the DLT 400 onlyit is not compatible with FM or IR transmitters.
