The Allen & Heath Qu-SB is equipped with 16 AnalogiQ digitally controlled microphone preamps designed to deliver warm, natural, and transparent audio performance. These preamps offer ultra-low distortion and an exceptionally low noise floor, ensuring pristine sound quality for vocals and instruments. Digital recall allows engineers to save and instantly recall gain settings, improving workflow efficiency. This feature is especially valuable for touring bands and venues with recurring setups. Consistent audio performance is guaranteed across multiple sessions and locations.

The Qu-Drive USB recording system enables direct multitrack recording and playback without requiring a computer or external interface. Users can capture up to 18 channels of high-resolution audio directly to a USB drive. This makes the Qu-SB ideal for live concert recording, rehearsal tracking, and virtual soundchecks. Playback functionality allows quick review and mixing of recorded sessions. The system ensures reliable, hassle-free recording in any live sound environment.

The mixer includes four dedicated stereo iLive FX engines derived from Allen & Heath’s flagship live consoles. These processors deliver high-quality reverbs, delays, choruses, flangers, and modulation effects. Each effect can be fully customized to suit vocals, instruments, or entire mixes. Dedicated FX engines ensure zero compromise on processing power. The result is studio-grade sound enhancement for live and recorded performances.

The Qu-Pad iPad app allows complete wireless control of the Qu-SB from anywhere in the venue. Engineers can adjust levels, EQ, dynamics, and effects in real time without being tied to a fixed location. The built-in Automatic Mic Mixer (AMM) intelligently manages multiple open microphones. This reduces feedback, ambient noise, and mic spill during conferences or panel discussions. The combination ensures clear, professional sound in complex live environments.
