Allen&Heath QU-SB - portable digital mixer with 18 inputs and 14 outputs, rack-mountable, which can be used as a 32x32 USB recording audio interface. It features 16 AnalogiQ microphone preamps, a 5-core ARM processor, and a wide variety of integrated effects and processing, including a 4-band parametric EQ, compressors, delay, and reverb. The mixer is compatible with the ME Personal Mixing System and the dSNAKE digital connection system, offering up to 38 inputs. It is designed to operate with the Qu-Pad app, allowing you to mix from any point in the room when connected to a wireless network using an iPad.
