Allen & Heath’s Qu-SB is an ultra-compact digital mixer designed for iPad control, freeing you to mix from anywhere in the venue and providing a smart, portable solution for bands, AV and installation. The companion Qu-Pad app is a beautifully elegant, intuitive mixing interface, giving easy access to the full wealth of Qu features and setup options. On top of its 18 onboard inputs and 14 outputs, Qu-SB can be expanded up to 32 mono inputs and 24 outputs by connecting to one of our family of remote AudioRacks over a single Cat5 cable. Couple this with the Qu-You personal monitoring app for Android and iOS, plus the ME-1 personal mixers, and Qu-SB is a fantastic choice for bands looking for the same great monitor sound wherever they play. 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 while tweaking the PA, and then mix the show from the heart of the audience. Qu-SB’s 16 AnalogiQ total recall preamps feature zero crossing detection and an advanced padless 1dB step gain stage, closely allied to the DSP for optimal gain accuracy and audio transparency. The analog signal is captured by high class, low latency 24bit analog to digital converters matched to high quality 24bit digital to analog converters to deliver the required outputs. The AnalogiQ design has been refined over many months to offer superb transparency, minimal distortion and an ultra-low noise floor, with a warm, musical sound that is missing from some digital consoles.
