PDI•8 Card
The PDI•8 card options include sample rate conversion for each stereo AES/EBU
input, and status bit control (pro/consumer mode) for each output. When a PDI•8
card is first installed, its default settings are for sample rate conversion Off, and
channel status bits set to indicate the Pro (AES/EBU) format. In most
circumstances you won’t need to change these settings. However, if the device(s)
connected to the PDI•8 inputs cannot be made a clock master or slave (such as a
CD player with a digital out), enabling sample rate conversion on each affected
input will effectively re-clock the incoming data.

Occasionally you’ll run across a device that will not recognize the digital audio
output from the PDI•8 card. Changing the status bits on the affected output(s)
from Pro to Consumer (S/PDIF) may solve the problem.

Remember that with the AES/EBU format, channels come in pairs, so rather than
eight settings, you have four, one for each pair of channels.
