The Kopul 4-channel mic/line stereo mixer combines one microphone signal with three stereo line-level sources, providing a straightforward audio-mixing solution for content creators, musicians, DJs, presenters, podcasters, and audio enthusiasts.

Three stereo RCA input pairs accommodate media players, keyboards, turntables with line-level output, computers, audio interfaces, drum machines, and DJ mixers. Channel 2 also provides a 3.5mm TRS stereo input for convenient connection to smartphones, tablets, portable digital recorders, and other compact playback devices.

The balanced 3-pin XLR microphone input supports dynamic microphones and condenser microphones. Selectable 48V phantom power is available when a compatible condenser microphone requires external power.

Each of the four channels has an independent stepless volume knob, allowing the user to balance speech, vocals, music, instruments, and playback sources without repeatedly adjusting the connected equipment.

The completed mix can be sent through a stereo RCA output pair to powered speakers, amplifiers, recording devices, or other line-level equipment. A separate 3.5mm TRS stereo output supports headphone monitoring or connection to another compatible stereo device.

The mixer provides a signal-to-noise ratio greater than 90 dB and total harmonic distortion of 0.008%. It does not include equalization, built-in effects, wireless connectivity, digital audio connections, level meters, solo controls, or mute controls.

A compact, rugged steel chassis supports desktop, project-studio, mobile sound, live-event, multimedia-workstation, home-theater, and small PA applications. The mixer operates from 12V DC power supplied by a power adapter accepting 100 to 240V AC at 50 or 60 Hz.
