Allen & Heath’s SQ-6 digital mixer is built for professionals in demanding live sound applications. XCVI 96kHz FPGA engine provides unrivalled power and audio fidelity with high resolution audio and ultra-low latency. The SQ-6 offers the tools you need for any mixing needs from AV and corporate events to live events and houses of worship.

Mixer is equipped with 24 onboard preamps and 8 stereo FX engines with dedicated return channels and access to the RackExtra FX library. In-ear monitoring setups are supported with the 12 stereo mixes, while multi-mic environments work well with Automatic Mic Mixing.

Powerful processing lets you create your best mix. All 48 inputs have HPF, a super-fast gate with sidechain and filter, 4-band parametric equalizer, and Peak/RMS compressor. Mixes have a parametric and 28 band graphic EQ along with compressor as standard. XCVI core allows every compressor in the SQ-6 to have its own parallel path without having to worry about phase or coherency.

Design is centered around a touchscreen, framed with high-grip illuminating encoders to create a blend of visual feedback and hands-on control. Drag and drop channels and mixes to any strip and customize naming and color coding on strip displays to build a personal mixing setup. Three tier all metal chassis and extruded aluminum light bar keep the mixer protected in tough environments.

Advanced automatic mic mixers (AMMs) are fully integrated in the mixer with no added latency. These ensure the mixer meets the needs of mixing conferences, panel talks, and TV shows.
