AVer COMEXMC20 Expansion Microphone for VB342 Pro & VB350
Scalable audio coverage for any size room.
The AVer COMEXMC20 Expansion Microphone extends the audio pickup of the AVer VB342 Pro and VB350 4K PTZ video bars, delivering clear voice capture across a 20-foot diameter coverage area. Designed for medium-to-large conference rooms, training spaces, and boardrooms, this microphone ensures every participant is heard with crystal-clear precision. With a dedicated Mic In port for daisy-chaining up to four expansion microphones, the COMEXMC20 scales to handle rooms of virtually any size. The included 20-meter (65.6’) cable provides generous reach for flexible placement throughout larger meeting spaces.
Wide 20-Foot Coverage Diameter
The COMEXMC20 captures voices across a full 20-foot diameter, ensuring participants seated anywhere around the conference table are picked up clearly. This broad coverage area makes it ideal for extending the audio reach of your VB342 Pro or VB350 video bar to accommodate more participants in larger rooms.
Daisy-Chain Up to Four Microphones
Each COMEXMC20 includes a dedicated Mic In port that allows you to daisy-chain additional expansion microphones. Connect up to four expansion microphones together to cover even the largest boardrooms, classrooms, and multi-use spaces — ensuring complete audio coverage regardless of room size or layout.
High-Fidelity Audio
With a wide 120 Hz to 16 kHz frequency response, the COMEXMC20 captures the full range of human speech with clarity and detail. Voices sound natural and intelligible, ensuring remote participants can follow conversations without straining to hear.
Easy Deployment
The expansion microphone connects directly to the VB342 Pro or VB350 video bar — no drivers, no software configuration. Simply plug in the cable and the microphone is immediately active. The low-profile tabletop design sits unobtrusively on the conference table, blending into any professional meeting environment.
Requires AVer VB342 Pro or VB350 Video Bar
This expansion microphone is designed exclusively for use with the AVer VB342 Pro and VB350 4K PTZ video bars (sold separately). It is not compatible with the original VB342 or VB342+ soundbars, which use a different expansion microphone (COMVBEMIC / COMVBM20M).
