Allen & Heath SQ6+ Digital Mixer
The Allen & Heath SQ6+ is a professional 48-channel, 44-bus digital mixer that balances extensive hands-on control with a compact and portable design. Equipped with 25 motorised faders, 16 assignable SoftKeys, and four SoftRotaries, it provides fast and intuitive control for larger productions, complex live shows, installations, broadcast applications, and multitrack recording.
At the heart of the SQ6+ is Allen & Heath’s 96 kHz XCVI processing core, delivering high-resolution audio and ultra-low-latency performance. Every input channel includes a high-pass filter, gate with sidechain and filtering, freely assignable insert point, four-band parametric EQ with RTA, and Peak/RMS compressor. Mix outputs feature parametric EQ, 28-band graphic EQ, and compression.
The responsive 9-inch touchscreen features a clear dark graphical interface designed for fast navigation in different mixing environments. Channels and mixes can be dragged and dropped onto any strip, while custom names, colour coding, and chromatic channel metering provide immediate visual feedback. Six configurable fader layers make it easy to organise channels, mixes, effects, and control functions according to the requirements of each production.
The SQ6+ includes eight RackExtra FX engines with dedicated stereo returns and four built-in RackUltra FX engines with dedicated stereo sends and returns. It also supports Allen & Heath’s DEEP processing add-ons, allowing models of classic analogue processors to be integrated directly into channel and mix strips without adding latency.
An integrated 32 × 32 USB audio interface supports multitrack recording, playback, livestreaming, virtual soundchecks, and DAW control at both 96 kHz and 48 kHz. The built-in SQ-Drive recorder enables direct recording and playback using a USB drive, supporting up to 16 channels at 96 kHz or 32 channels at 48 kHz without requiring a computer.
For system expansion, the SQ6+ features a 128 × 128 Intelligent SLink port, providing access to Allen & Heath’s Everything I/O ecosystem of digital stage boxes, expanders, and compatible consoles. A dedicated expansion slot supports optional Dante, MADI, Waves, and additional SLink cards.
Two independent 24-channel Automatic Mic Mixers can operate simultaneously for separate zones or be combined into a single 48-channel AMM. This makes the SQ6+ particularly suitable for conferences, panel discussions, houses of worship, corporate events, and broadcast applications.
Built around a durable all-metal chassis, the SQ6+ is designed to withstand the demands of touring and permanent installation while maintaining a streamlined and professional appearance.
