Allen & Heath QU-SB-RK19 19-Inch 4U Rack Mount Kit for Qu-SB Mixer

Allen & Heath QU-SB-RK19: A Proper Rack Home for the Qu-SB

The Allen & Heath QU-SB-RK19 is a rack mount kit that converts a freestanding Qu-SB digital mixer into a 19-inch, 4U rackmount unit. It is a small accessory with an outsized effect on how a Qu-SB rig survives the road, turning a standalone box into a bolted-down rack component. The kit ships as a matched pair of steel rack ears with the mixer fixing screws and rack screws included, so installation is a quick, tool-light job. For anyone building a touring or install output rack around a Qu-SB, it is the difference between a mixer that shifts loose in transit and one that is anchored for the life of the system. That tidy permanence is exactly what a rack is supposed to deliver.

Steel Ears Built for the Road

The ears are formed from steel so they hold the Qu-SB rigidly through the constant vibration and rough handling of touring, where a flimsy mount would let the mixer sag and stress its rear connections. That same rigidity serves permanent installs, where the mixer may be racked once and left untouched for years behind an amplifier system. Because the kit is a straightforward pair with all the required screws, there is nothing proprietary to fail and nothing else to buy. It suits a flightcased front-of-house rack just as well as a fixed equipment-room rack in a theater or house of worship. For a professional Qu-SB deployment, it is the simple, dependable way to make the mixer a permanent rack citizen.

What the Kit Includes and Fits

The QU-SB-RK19 is designed specifically for the Qu-SB and occupies 4U of standard 19-inch rack space when fitted. In the box you get two steel rack ears, the screws that fix them to the mixer chassis, and the rack mounting screws with washers that secure the assembly into the rack rails. Because everything needed is supplied, there is no trip back to the hardware store mid-build and no guessing at thread sizes. Rack the Qu-SB once and it becomes part of a clean, serviceable audio rack that an assistant can wire, coil and load in seconds. It is the correct, factory-matched way to integrate a surface-less Qu-SB into any professional rack system.
