SQ-5 has all the onboard I/O you need for standalone operation. Thanks to its SLink intelligent port, SQ can also be expanded up to a total of 48 mic inputs via a family of 96kHz and 48kHz rack and stage box expanders making it a flexible, mix ‘n’ match solution for owners of other Allen & Heath digital systems. You can also link your SQ directly to another SQ, an Avantis or even a dLive system.
