A&H Digital Mixer 18 in / 14 out

The Allen & Heath QU-SB is a compact, rack-mountable digital mixer engineered for applications where powerful processing is required without a traditional control surface. Delivering 18 inputs and 14 outputs in a streamlined 5U rackmount chassis, the QU-SB is purpose-built for installed sound, portable live rigs, and personal monitoring systems where remote wireless control is the preferred workflow.

At its core, the QU-SB features 16 AnalogiQ recallable mic/line preamps renowned for their low-noise performance and warm analogue character. Four stereo FX engines provide studio-grade reverb, delay, and modulation effects, while comprehensive EQ, dynamics, and routing deliver full mix control across 12 configurable mix outputs.
