Key specifications

How to use

Connect microphones and line sources to the appropriate inputs, set gain using the low-noise preamps and shape the signal with the channel British-style EQ. Engage the one-knob compressor on mono channels as needed to control dynamics. Assign and edit effects on the 24-bit FX processor and route them to individual channels, busses or the main mix. Use the feedback detection and voice canceller features during live shows to reduce feedback and isolate vocals. Connect the mixer to a computer via USB to record or stream at up to 48 kHz.

Recommendations

For best results, set input gains so that peaks do not clip the meters, use the compressor sparingly to preserve natural dynamics, and apply the built-in EQ for gentle tonal adjustments. When recording via USB, use a 48 kHz sample rate for optimal fidelity and monitor levels to avoid digital clipping.
