24-bit/192kHz ADAT™ interface operation
The card provides digital outputs for all eight ISA428 MkII channels, which operate over the sample frequency ranges 44.1-192kHz.
The card features two ADAT™-type 'lightpipe' output connectors. For speeds up to 48kHz, both connectors transmit all 8 channels
simultaneously. However, ADAT™-type connectors are bandwidth-limited at sample rates 88.2kHz and 96kHz - each audio channel
uses two ADAT™ digital channels to accommodate the increased quantity of data (SMUXII). At sample rates 176.4kHz and 192kHz,
each audio channel uses four ADAT™ digital channels to accommodate the increased quantity of data (SMUXIV).
The ADAT™ output connectors operate as follows:
44.1/48kHz sample rates:
Connector 1 = channels 1 to 8
Connector 2 = channels 1 to 8 (identical to connector 1)
88.2/96kHz sample rates:
Connector 1 = channels 1 to 4
Connector 2 = channels 5 to 8
176.4/192kHz sample rates:
Connector 1 = channels 1 and 2
Connector 2 = channels 3 and 4
