Focusrite OctoPre 24-96 AD ADAT Card24-bit/96 kHz ADAT interface card
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.
The ADAT output connectors operate as follows:
44.1/48Khz sample rates:
- Connector 1 = channels 1 to 8 in parallel.
- Connector 2 = channels 1 to 8 in parallel (identical to connector 1)
- 88.2/96Khz sample rates:
- Connector 1 = channels 1 to 4.
- Connector 2 = channels 5 to 8.
