The Gold Channel is capable of upsampling the signal to 88.2 / 96 kHz and applying its processing there, and then downsampling again to 44.1 / 48 kHz, - but - the converters and the digital I/O are incapable of accepting or slaving to 88.2 / 96 kHz - only 44.1 / 48 kHz are supported for the digital I/O and wordclock.
When running the Gold Channel at 88.2 / 96 kHz, you can run either:
4 insert effects (processing positions) per channel (4 x 2 = 8 insert effects) at 44.1 / 48 kHz,
1 insert effect (processing position) per channel (1 x 1 = 2 insert effects) at 88.2 / 96 kHz,
3 insert effects (processing position) on channel one at 88.2 / 96 kHz.
It is not possible to upgrade the hardware / software of a Gold Channel to support 88.2 / 96 kHz on its input and outputs.
