Allen & Heath - 'QU-SB'

including remote wireless controlThe ‘Qu-SB’ from Allen & Heath is a wonderfully compact digital mixer which hands you the freedom to mix from any position in the venue and delivers a sleek, portable solution for performng musicians and artists.
Qu-SB is light enough to be carried under one arm and is packed with Allen & Heath’s highly praised suite of FX emulations and dynamics, making the Qu-SB the perfect replacement for your old analogue mixer and a bulky rack of outboard FX units.
The accompanying ‘Qu-Pad’ app is a brilliantly intuitive interface for setting up the show how you like things to be, and also mixing in real-time from your iPad. There’s also a fully customisable Qu-Control app that allows you to use just a few essential controls that you require in front of you for quick and easy access throughout the show.
Once paired with the ‘Qu-You’ personal monitoring app for Android/iOS and Qu-SB soon becomes a superb choice for mixing your own monitors and allows you to quickly attain the same sound night after night, no matter the venue.
Alongside the 18 on board inputs and 14 outputs, Qu-SB ensures you are future-proofed with plug & play expansion up to 38 inputs / 24 outputs via a collection of remote AudioRacks.
Qu-SB Mixing Apps

Unparalleled controlAll of this gargantuan processing power and complex functionality is fantastic; however, it counts for little if one can’t access the controls you need in an instant. Qu-SB was designed to flow seamlessly with the fully-featured Qu-Pad iPad app, delivering rapid, simple access to all settings, inclusive of channel processing, meter and RTA views, FX racks, scene management, USB audio control ,setup menus and so much more.

The freedom to mix anywhereQu-Pad hands you instant access to all live mixing controls and allows you to EQ and mix monitors on stage, walk freely through the venue whilst you make tweaks to the PA, and mix the gig from on-stage, or in the heart of the crowd by connecting to the mixer via Wi-Fi.
Qu-You lets up to seven artists have full control over their own monitor mixes via any iOS or Android device, and frees up the engineer to spend more time focusing on mixing for that evening’s audience.
Qu-Control is a hugely customisable iOS app providing an easy to use interface for non-technical users to control the key parameters of Qu mixers when technical operators may not be available.
'AnalogiQ' Preamps

16 world-class preampsQu-SB’s 16 AnalogiQTM total recall preamps boast zero crossing detection and an advanced padless 1dB step gain stage, faithfully allied to the DSP for prime gain accuracy and audio transparency. The analogue signal is captured by world-class, low latency 24bit analogue to digital converters matched to high quality 24bit digital to analogue converters to deliver the desired outputs.
The AnalogiQTM design has been optimised over the course of many months to deliver unparalleled transparency, minimal distortion and super-low noise floor, with a rich, musical sound that is lacking from some digital consoles.
ProFactory Mic Presets

in conjunction with leading manufacturers
Allen & Heath has teamed up with leading microphone manufacturers and top engineers at Audio-Technica, Sennheiser, and Shure to provide EQ Library presets for a large number of popular and industry standard microphones.
Presets for vocals, electric guitar, acoustic guitar, drums, brass and woodwind have been painstakingly crafted to offer you the best possible starting point for the source and your microphone of choice. Whether you’re a keen amateur or a seasoned professional, you can get to work quickly and easily, saving valuable time so you can concentrate on EQ’ing the source and room acoustics.




Rack FX

4 stereo RackFX enginesQu-SB’s dynamics and FX algorithms are derived from those used in Allen & Heath’s pro touring consoles. Some of the world’s most respected audio engineers have chosen to use RackFX on tour in preference to top-end plug-ins and external FX units. Qu-SB boasts 4 stereo RackFX engines, featuring lovingly crafted emulations of legendary classic reverbs, gated reverbs, delays, modulators, flangers and more.
FX are returned to the mix on dedicated return channels, so you’re not tying up your mono and stereo input channels. Each Stereo FX Return has a dedicated 4 band PEQ.
Huge Scope for Expandability

expand by up to 32 mono inputsQu-SB can be expanded to up to 32 mono inputs via dSNAKE, allowing a convenient Cat5 connection to a combination of remote AB168, AR2412 or AR84 AudioRacks. dSNAKE is our proprietary networking solution, boasting a transport latency of only 105us over cable runs of up to 120m / 390’.
The AudioRacks unleash all the power of Qu-SB, giving you access to extra outputs for Stereo Matrix, Groups, and extra monitor Mixes.
Automatic Mic Mixer (AMM)

Mix Up to 16 microphone sourcesAMM is vital in applications such as conferences, meetings and panel discussions where a number of microphones are open at the same time, reducing background noise and minimising the risk of feedback.
The Automatic Microphone Mixer feature helps the engineer to manage the levels of multiple mic inputs, ensuring that each speaker’s contribution is heard. The D-Classic dynamic gain sharing algorithm is inspired by industry standard automixers. Up to 16 microphone sources can be mixed at once, with each channel having a priority setting which determines its ‘weight’ in the total system gain.
