All SQ models offer the same 32x32 channels @24/96 via USB
Same numbers across all models for Slink, depending on protocol 32/64/128 channels with a max of 128 @24/96 via gigaACE.
However, the Digital IO/ Port of SQ-5/6 is spec´d as 64x64, while SQ-7 is positioned as 128x128:
“A digital I/O Port shall be provided to accept optional cards, supporting a maximum 128x128 channels and the ability to interface with 3rd party AoIP protocols such as Dante and Waves.”
Is that a typo? Or is DANTE output really different on the SQ-7? Maybe a different DANTE I/O card for SQ-7 only (which would surprise me)?
Asking because the PCIe I/O on the DAW will have 128x128 and I´m torn between 2x SQ-5 or 1x SQ-7.
All three models (5, 6 & 7) have an IO port capable of up to 128 x 128 channels (using the Slink option card), whilst also being compatible with other SQ option cards for Waves and Dante which are 64 x 64 channels. The core and processing power of the SQ is the same across the series, so if there is a difference in any of our documentation, please forward the information to support@allen-heath.com and we can take a look.
