Independent shopping perspective
The Korena take
Allen & Heath’s SQ-Rack puts a 48-channel digital mixer and 96kHz XCVI FPGA core into a 4U rack format. It mixes 48 input channels to main LR and 12 stereo mixes, with fully recallable digitally controlled mic preamps offering up to +60 dB gain, 48V phantom power, and switchable pads. Local SLink connectivity expands I/O over a single digital snake cable, while the option-card port broadens digital-routing choices. A 7 inch touchscreen, dedicated fader screen, and control apps support operation in venue, in-ear monitoring, and touring systems.
Strong match
Who this is for
- Rack-based venue systems needing 48 input channels, LR, and 12 stereo mix outputs.
- Building an in-ear monitoring system with connections to Allen & Heath personal mixing systems.
- Multitrack recording or playback through USB in a rack-mounted mixing setup.
