The Kopul two-channel mini mixer is designed for filmmakers, videographers, interviewers, and content creators who need to connect and balance multiple microphones with a DSLR, mirrorless camera, or camcorder featuring a 3.5mm microphone input.

The mixer provides separate left and right 3.5mm mono microphone inputs for two independent microphones, along with a dedicated 3.5mm stereo input for a stereo microphone. A stereo 3.5mm output connects the mixer to the camera through the supplied coiled cable.

A mono and stereo selector lets users route the two microphone signals to separate left and right channels or combine them into a single mono signal. Dual stepped trim knobs provide controlled level adjustment, making it easier to balance microphone sources before audio reaches the camera.

The fully passive circuit requires no batteries or external power and is designed to avoid introducing unnecessary electronic noise into the recording chain. It outputs a microphone-level signal and is intended for compatible microphones rather than line-level audio sources.

Its rugged metal bracket mounts directly to a compatible camera shoe and includes three integrated shoe mounts on the top and sides. These mounts can hold microphones, compact lights, wireless microphone receivers, and other shoe-compatible production accessories.

The compact camera-mountable design supports synchronized in-camera audio recording for interviews, filmmaking, event coverage, mobile journalism, and other field-production applications.
