Allen Heath SQ 796kHz, 48 Channel,36

Allen & Heath SQ-7 is a compact 96 kHz digital mixer built around a 48×36 XCVI FPGA processing matrix. The surface provides 32+1 motorised faders across 6 layers, a 7" colour touchscreen, 16 SoftKeys and 8 Soft Rotaries, with 32 local mic/line XLR inputs and deep onboard processing including DEEP and automatic mic mixing.

Key Features

• 48 input channels / 36 total busses; 12 stereo mixes (Aux or Group) + Main; 96 kHz sample rate, up to 96-bit accumulator
• 32 local mic/line XLR inputs (fully recallable preamps); 2× ¼" stereo TRS + 1× 3.5 mm stereo input; dedicated Talkback XLR
• 18 assignable local outputs (16 XLR + 2× ¼" TRS) plus AES digital output
• SLink EtherCON remote audio (dSnake/ME, DX or GigaACE/GX, up to 128×128); I/O Port for optional Dante / Waves / extra SLink
• 33 motorised faders (6 layers); 7" capacitive touchscreen; 16 SoftKeys; 8 Soft Rotaries; channel LCD displays
• 8 stereo FX engines; DEEP processing ready; DEEP Automatic Mic Mixing (2×24 or 1×48); 32×32 USB audio streaming; SQ-Drive USB-A record/playback
• Latency <0.7 ms local mic input to Main L/R; mains 100-240 V AC, 50/60 Hz, 110 W max

Overview

SQ-7 is the largest surface in the SQ series (not SQ-5 / SQ-6). All SQ mixers share the same 48×36 / 96 kHz core; SQ-7 adds more local I/O, SoftKeys and Soft Rotaries on a wider 33-fader surface.
