Adjust individual channel levels and master volume to achieve the desired mix, and route the combined output to a power amplifier or active speakers. Check input gain settings and mute switches before starting to avoid clipping and feedback.
Usage recommendations
For reliable operation, place the mixer on a stable surface or mount in a suitable rack. Use balanced cables for longer runs to reduce noise, set channel gains conservatively to prevent distortion, and keep firmware/drivers for connected computers up to date when using USB audio. When using Bluetooth sources, maintain a clear line of sight between the transmitter and mixer to minimize dropouts.
