Comica Audio CVM-WM300B Overview

  • 1Description

Operating in the UHF spectrum (520 to 548.5 MHz for Group A, 550 to 578.5 MHz for Group B), the Comica Audio CVM-WM300B is a camera-mountable UHF wireless system that comprises a bodypack transmitter with a lavalier microphone, a wireless handheld microphone, a dual-channel receiver, and a host of accessories. The receiver and bodypack transmitter are powered via built-in, lithium-ion polymer rechargeable batteries, while the handheld mic transmitter is operated via two AA batteries. The system allows you to transmit two mic- or line-level audio signals simultaneously to the receiver, which can be set to mono or stereo output mode, making it ideal for interviews or presentations with two speakers, or for transmitting a mix when working on ENG, video, or music productions.

The CVM-WM300B offers 96 selectable frequency channels that can be quickly changed to avoid signal interference, and it lets you adjust the RF signal strength for reliable operation at a maximum range of approximately 393 feet. The receiver provides an audio output to the camera as well as a monitor output for real-time monitoring of your signal. The CVM-WM300B is supplied with two output cables (one 3.5mm, one 3.5mm to XLR), a micro-USB charging cable, two belt clips, a wind muff, two cold shoe mounts, and a carry case.
