Allen & HeathQu-SB Rackmountable Digital Mixing System
1/7
Independent shopping perspective
The Korena take
Qu-SB puts an 18-input, 14-output digital mixer into a compact rackmountable format that can be carried under one arm. Set up and mix from the Qu-Pad iPad app, then give performers access to personal monitor control through Qu-You. Saved settings, multitrack recording, playback for virtual soundchecks, onboard dynamics and four stereo FX engines make it a practical center for a band that handles its own live mix. Add remote AudioRacks when the system needs more I/O.
Strong match
Who this is for
- Bands mixing their own monitors while keeping show control available around the venue
- Live setups that benefit from saved settings and playback-based virtual soundchecks
- Recording input channels and Main LR to a Mac or PC during live work
Consider the trade-offs
When to look elsewhere
- Systems requiring more than 18 onboard inputs or 14 onboard outputs without adding remote AudioRacks
