description

Compact audio mixer with options for 2 mono + 2 Stereo input channels, plus a minijack stereo input. Each mono channel has a combo XLR/jack input with switchable +48V phantom power in pairs for XLR inputs.

Mono mic/line channels feature Gain control and a low-cut switch to minimize handling noise. Each channel also includes High/Low EQ and FX level controls for fine-tuning sound. Channels can be linked in pairs for stereo left and right output.

The onboard DSP effects engine has 99 presets for delay, reverb, and modulation, with adjustable parameters via two control knobs.
