24-bit/96 kHz ADAT 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.

External word clock synchronisation is possible using the rear panel BNC connector. 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 above 48 kHz - each audio channel uses two ADAT digital channels to accommodate the increased quantity of data, hence the need for two ADAT connectors to allow 8 channels of conversion at high speed.

• Dynamic Range = 110dB
  
• Clock Jitter = less than 250 picoseconds
  
• Clock Jitter when sync'd to an external clock = 1 nanosecond
  
• THD+N AMPL = -109dBFS 'A' weighted
