The CVM-WM200A is a dual-transmitter and receiver wireless
microphone kit from Comica. This kit runs on AA batteries (not included)
and has a maximum range of 120m.
To begin using this kit, take out the transmitters and receiver and
install 2 AA batteries in each unit. On the transmitters, use the large
switch on the side to designate which unit is the A unit and which is
the B. Then, you can either assign each a channel manually or use the IR
search function to allow the transmitters and receiver to identify
which channel has the least amount of interference and automatically
assign themselves to that channel. Attach each unit to the user via belt
clip, camera cold shoe mount, or an accessory arm via the 1/4-20 mount
on the back.
Next, attach the included lavalier microphones to the two
transmitters and clip them onto the subjects. Use any of the three
included adapters to attach the receiver to the camera, speaker, mixer,
or recorder that will be receiving the signal. For real-time audio
monitoring, headphones can be inserted into the receiver, next to the
Line Out port. Take a test sample of the audio, and begin recording!
When you are done, the entire kit and all of its accessories fit neatly
into the included hard case.
