6. Operating Instructions
6.1 Basic Operation
- Power On: After all connections are made, switch the mixer's power to ON.
- Gain Control: Adjust the GAIN knob for each input channel to set the input level. Aim for the signal to peak around 0 dB on the level meters during the loudest parts of your audio.
- Compressor (Channels 1-2): Use the COMP knob to apply compression to microphone inputs. Turn clockwise to increase compression.
- Equalization (EQ): Use the HIGH, MID, and LOW knobs on each channel to adjust the tonal balance.
- Level Faders/Knobs: Adjust the LEVEL faders (or rotary knobs for stereo channels) to control the volume of each channel in the main mix.
- Main Mix: Use the MAIN MIX fader to control the overall output volume of the mixer.
- Headphone/Control Room Level: Adjust the PHONES/CTRL ROOM knob to set the monitoring volume.
6.2 USB Audio Interface Usage
When connected to a computer via USB, the Q802USB acts as a 2-in/2-out audio interface:
- Recording: The main mix output of the mixer is sent to your computer via USB. You can record this stereo signal in your digital audio workstation (DAW) software.
- Playback: Audio from your computer can be routed back to the mixer via USB. Use the 2-TRACK/USB TO MAIN MIX button to send this audio to the main mix, or 2-TRACK/USB TO PHONES/CTRL ROOM to send it only to your headphones/control room monitors.
7. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Behringer Q802USB mixer.
- Cleaning:
- Always disconnect the power before cleaning.
- Use a soft, dry, lint-free cloth to wipe down the exterior.
- For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by a dry cloth.
- Avoid abrasive cleaners, solvents, or waxes, as they can damage the finish.
- Storage:

- Protect it from dust and moisture when not in use, ideally with a dust cover.
