Digital Interface Card for the OctoPre

This card provides digital outputs for all eight OctoPre channels, which operate over the full sample frequency range (44.1, 48, 88.2 and 96 kHz) and can be dithered to 16-, 20-, or 24-bit depths depending upon the destination. The card features two ADAT™-type lightpipe output connectors and AES and SPDIF format outputs via a 9-pin D-type connector on the rear panel.

As with the ADAT-type outputs, the full range of sample rates and bit depths are available, and the converter may be synchronised to an external word clock source if required. To access the digital signals from the 9-pin D-type AES/SPDIF output connector the A/D card must be purchased with either an AES or SPDIF D-Type conversion cable, available separately. Either 8 AES or 8 SPDIF outputs can be used simultaneously with 8 ADAT outputs and the OctoPre's analogue outputs.
