The Allen & Heath 19-inch Rack Ear Kit is used to mount the Qu-16 Digital Mixer in a standard 19-inch rack or flight case. These fit over the plastic trims. Allen & Heath is known for building high quality mixers for the last 40-plus years. At any time of day or night, across the globe, there is an Allen & Heath mixer out there working hard, sounding great and making life a little easier for the person at the controls. Back in the early 1970s, Allen & Heath hand-built consoles in a tiny factory in London for elite bands like Pink Floyd and The Who. These days Allen & Heath customers are spread across almost every environment imaginable, including touring, theatres, churches, nightclubs, TV and radio stations, recording studios and countless other places where great sound matters.
