Powerful Mixing and Recording Capabilities

From live music performances to conference audio and panel discussions, the Allen & Heath Qu-SB is a powerful, portable digital mixer. It offers 16 mic/line inputs, and can be expanded to 32 channels via Allen & Heath AudioRacks (not included). Use the Qu-Pad iPad app to access all mixer functions, from channel faders and metering, to effects racks, scene management, and USB audio control. Performers onstage can use the Qu-You app for iOS and Android to control their own monitor mixes. And with effects derived from the iLive console series, mic presets for leading microphone models, built-in multi-track USB recording and much more, the Allen & Heath Qu-SB is an amazingly versatile rackmount mixer.

Freedom to mix anywhere with the Qu-Pad app

Add Allen & Heath's Qu-Pad iPad app to your rig and you'll have the freedom to adjust your monitors from onstage, tweak the PA while roaming about the venue, then mix the show from FoH. You can personalize the GUI to create your own control panel, perfect for offering customized control for any application. Whether you're mixing your band live, recording in the studio, or you're in charge of setting up a permanent sound installation for your school, church, or company conference hall - Sweetwater has found the Allen & Heath Qu-SB to be an outstanding solution that's at once flexible, scalable, and rock-solid reliable.

AnalogiQ preamps and 24-bit conversion, for warm, musical sound

Allen & Heath fortified the Qu-SB with 16 of their superb AnalogiQ total-recall preamps. Featuring phantom power, zero crossing detection, and a unique padless 1dB-step gain stage, the preamps are married to the DSP for optimum transparency and gain accuracy. The analog signal is captured by high-quality, low-latency 24-bit A-D converters matched to high-grade 24-bit D-A converters. A&H has spent considerable time refining the AnalogiQ design so it gives you stellar transparency, with minimum distortion and a vanishingly low noise floor.

Power-packed with smart features

If anyone knows live mixing, Allen & Heath is at the forefront. That's why they're able to load the Qu-SB with smart features you'll come to rely on, night after night. Like a built-in interface that streams multitrack audio to your Mac or PC via a flexible patching system. Or the integrated multitrack USB recorder that gives you 18 channels of 48kHz, 24-bit recording and playback straight to and from your USB hard drive. Impressive? How about every channel being outfitted with Channel Ducker, which provides auto signal attenuation for an endless number of applications? Or compatibility with A&H's ME Personal Mixing System? This allows any number of optional ME-1 personal mixers be chained from Qu-SB's dSnake port (or from an AR2412 / AB168 AudioRack, if you've got one connected), giving each performer control over his or her own mix and leaving the engineer free to concentrate on the audience experience.

Powerful functionality added in v1.9 software

The Qu series ecosystem is constantly being refined, and v1.9 of the Qu software adds even more functionality. More mic presets for Shure, Sennheiser and Audio-Technica mics are now available, making it easier than ever to dial in great sound fast with any mic in any application. You'll find a ton of advanced iPad control options too, like the ability to patch channels between dSnake, USB, Qu Drive and ME personal monitoring systems. You can set up various User profiles with different levels of permissions, manage your Scene memory, Copy/Paste channel settings, and manage USB devices. And v1.9 adds Windows DAW control support, for all popular Windows platforms.

Reviews

Small but mighty
I am so happy with this purchase. Allen & Heath has great products and this one fits the needs I have right now. Portable and powerful.
Music background: Worship leader, drummer, singer, acoustic guitar
Fantastic
I owned the Allen & Heath Qu-Pac and after 5 good years I decided to buy the Qu-SB. The Qu-SB is SO portable and I love the iPad interface over the on-screen interface of the Qu-Pac. Bottom line for me is this is a great mixer - so good that after buying one for my band, I decided to help install a second one at my church

Great job, hats off to Allen & Heath
Works like a charm
I bought the QU-SB for a 6 piece jazz group. I have a router that I use when we travel so we have WiFi that is secure and reliable. I am still learning how to use this, but so far it works really well. It is easy to setup and it is great having so many output mixes for the monitors. It is a very versatile system and the iPad controller works well, so long as the wifi connects properly.

Perfect solution for mobile setup
This Wifi Mixer meets ALL our needs to run a church band. Other reviews pretty much revealed all the benefits and cons (not too many cons for this great model), but one more thing we took advantage on top of this unit is I installed 5 IN EAR MONITORS in addition to the 2 stage monitors WITH THIS… high-quality, portable mixer!!!

This IEM setting supports bass, drums, keyboard1, keyboard2 and a guitar player, all without buying additional Personal Mixer modules! I am appreciated of how A&H done such a great job designing this mixer. I bought another mixer before this one (SC Ui16) and it didn't work out well due to the pre-amp noise issues (Qu-SB has better quality preamps).

Well, here is the trick of how I took advantage of the Outputs and the Qu-You App to support 2 stage monitors and 5 In-Ear Monitors:
1. Mix 1 and 2 goes to Stage Monitor L and R.
2. Mix 3 I assign to MTX 1 for drums' IEM
3. Mix 4 I assign to MTX 2 for bass' IEM
4. Mix 5&6 for guitar player, 7&8 for KB2, 9&10 for KB2, all WITH LyxPro Y-Cable 3.5mm TRS Male to 2 XLR Female Stereo Audio Y-Splitter Adapter Cable plus a 3.5mm female to female adapter so the headphone can connect to it.

Each of the 5 musicians can control their own IEM volume with Qu-You app, and since Qu-SB can only handle up to 8 connections, the remaining 2 spot I let one soundman (with Qu-Pad App) to control the PA balance, and one soundman assistant (also with Qu-Pad App) to help out the stage monitors. Of course if you have only one iPad or iPad mini, you can let one of the vocalist control the stage monitors from iPhone by Qu-You App (it is easy to select between which mix volume you want to control).

In this setup, all the musicians can hear sound from both of their in-ears.

This unit eliminates the bulky, heavy and space demanding traditional soundboard, and allows easy scene recall to the last-know-good-saved setting (which is a benefit with all digital mixers).

This portable mixer made our setup easy and light-weight, when mounted to a mobile rack along with all the wireless stations connected (our rack cover is deep enough to leave all the connections on without having to unplug them each time we setup/tear-down), and by adding a Furman power conditioner with 8 outlets built-in, also a drawer to the bottom of the rack to store all the cables, it greatly reduced our setup/tear-down time.

I greatly recommend this amazing Wifi-Mixer to anyone who is looking for a economy while high-quality solution!

So glad I got this mixer!
Got this for my own use in the home studio as an interface with my MacBook Pro (using Logic) and as a live console for local gigs. The features and flexibility for a $1000 board was way beyond my expectation. Recording our practices is a snap by either plugging in my laptop (which instantly recognizes it) or recording straight to a thumb drive plugged in directly to the unit. Our band gets the sound dialed in, everyone's ear monitor mixes and/or wedge mix, save it then set up at the gig and give them a L/R and our sound blows people away! The preamps blow anything else away in this price range. Love the multiple ways we can send to our DAW via the routing matrix. you do have to get a wireless router to use it but it is super easy set up and only need to do it once. The iPad app works great and interacts with no lag. I can give other band members individual control over their monitor mixes. The effects are wonderful. Gain structure, EQ, compression, gate on each channel and they sound great. I've been using digital board since the Yamaha 02R. It amazing to think that you used to have to spend $25,000 to get what this $1000 board does now and sound ao much better than those old 02R's! The only feedback is that as an audio interface for the DAW - playing back tracks requires going into the settings on the iPad and specifying USB as the source. If input monitoring was quicker and easier, I'd ditch my MOTU.
