The Allen & Heath SQ-5 is a compact, 48-channel digital mixer designed for live sound, studio recording, and broadcast applications. Built around Allen & Heath's 96kHz XCVI FPGA engine, it delivers exceptional audio quality with ultra-low latency. The mixer features a 7-inch capacitive touchscreen for intuitive control, 17 motorized faders in three layers, and an integrated 32x32 USB audio interface for seamless recording and playback. With DEEP processing, the SQ-5 offers studio-grade emulations of classic hardware compressors and EQs directly on board. It also supports expansion via SLink for up to 128 inputs and outputs, making it a versatile choice for a wide range of professional audio environments.
