The CVM-WM100 is a wireless lavalier microphone kit from Comica. This kit contains one transmitter, one receiver, one lavalier microphone with a 3.5mm connector, a soft case, and accessories like a wind muff, 3.5mm-XLR adapter, and cold shoe mounts for the transmitter and receiver.
To use this kit, install two AA batteries(not included) in both the transmitter and receiver, then turn them on. Select one of 48 available channels, and monitor for signal interference. If there is a lot of interference on one channel, scan through others until you find a clean, noise-free channel to use. Both the transmitter and receiver can be worn on the belt, mounted to the included cold shoe mounts, or attached to an accessory arm via the 1/4-20 mounting point on each unit.
When a solid signal is established, connect the lavalier mic and, if you desire, a secondary sound input device to the transmitter. Plug the receiver into the camera, recorder, or speaker of your choice (for speakers, make sure they have sufficient amplification to adequately handle the signal). Test the levels by taking test-audio, and get to recording! When recording is finished, the entire kit can be placed into the included soft carrying case for storage and transport.
