Thank you for choosing Kopul.
The CMX-1 is a compact, camera-mountable 
two-channel audio mixer ideal for shooting 
videos with a DSLR camera or camcorder. It 
features mono inputs for two separate 
microphones and a stereo input for a stereo 
mic. The levels of the left and right channels 
are controlled with the dual trim control knobs. 
Set the mono/stereo switch to mono (M) to 
send the signal from a mono microphone to 
both left and right channels. Select stereo (S) 
to record with one stereo microphone or two 
mono microphones. The mixed levels are 
output to the mic input on your camera with 
the enclosed coiled cable. The CMX-1 
features three integrated shoe mounts for use 
with microphones, wireless receivers, or other 
mountable accessories.
