Allen & Heath Qu-SB Portable 18-In/14-Out Digital Mixer

Allen & Heath Qu-SB Overview

Designed to accommodate a wide variety of live-sound reinforcement and recording scenarios, the Allen & Heath Qu-SB is an 18-in/14-out rack-mountable, console-less digital mixer that doubles as a 32x32 USB recording interface. Featuring 16 of the company s recallable AnalogiQ microphone preamps, and powered by a 5-core ARM processor, the Qu-SB provides a variety of integrated effects and processing, including channel-independent 4-band parametric EQs, compressors, delay, and reverb.

The mixer is compatible with both the ME Personal Mixing System and dSNAKE digital connectivity system from Allen & Heath, which allows for up to 38 inputs. The Qu-SB is designed to be used with the Qu-Pad app, allowing you to use your iPad to mix from anywhere in the venue when connected to a wireless network.

Qu-Pad Mixing App

• Qu-SB is designed to integrate seamlessly with the Qu-Pad iPad app, providing super-fast, easy access to all settings, including channel processing, meters and RTA views, FX racks, scene management, USB audio control, setup menus and much more
• Qu-Pad connects to the mixer over Wi-Fi and gives you the freedom to adjust the monitors on stage, roam around the venue whilst tweaking the PA, and then mix the show from the heart of the audience

AnalogiQ Preamps

• Qu-SB s sixteen AnalogiQ total recall preamps feature zero-crossing detection and an advanced pad-less 1 dB step gain stage, closely allied to the DSP for optimal gain accuracy and audio transparency. The analogue signal is captured by high-class, low-latency 24-bit analog-to-digital converters matched to high-quality 24-bit digital-to-analog converters to deliver the required outputs. The AnalogiQ design offers superb transparency, minimal distortion and an ultra-low noise floor, with a warm, musical sound

Qu-Drive

• Qu-SB has an integrated multitrack USB recorder, providing 18 channels of 48 kHz/24-bit recording and playback straight to/from your USB hard drive. Mixes and FX returns can be recorded alongside channels, and multitrack audio can be played back to the mixer for virtual soundchecks
• An independent set of controls is provided for quick stereo recording of the main LR or other mix outputs, and a 2-track USB return can be routed to ST3 for playback of stereo WAV files such as walk-in music

iLive FX

• Qu-SB s dynamics and FX algorithms are derived from the FX used in the iLive pro touring series. Qu-SB boasts 4 stereo iLive FX engines, featuring emulations of legendary classic reverbs, gated reverbs, delays, modulators, flangers and more

Automatic Mic Mixer (AMM)

• AMM 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 minimizing the risk of feedback. The Automatic Microphone Mixer feature helps the engineer 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
