The ADAT timecode is not in sync
The tape is formatted to 48 kHz, but played back at 44,1 kHz (Pitch). This 'Blackface'
problem cannot be solved in a satisfactory way.
ADAT timecode is running, but Cubase does not start 'Play' automatically
The input displayed in 'Sync Ref' is not in sync mode. Sync mode is essential, because
ADAT's so-called time code is really a sample position, and is therefore only valid for
synchronous audio data.
Sync is displayed (referring to the card's clock), but the incoming data is not in sync with the
sample position received at the ADAT Sync In. Then Cubase does not start. Remedy: Set
'Pref. Sync Ref' to the input corresponding to the received ADAT Sync signal.
Sync mode wasn't activated (button in the transport panel), or ASIO 2.0 has not been
chosen as the SMPTE sync source.
The input signal cannot be monitored in real-time
ASIO Direct Monitoring has not been enabled, and/or monitoring has been globally disabled.
The first 8 channels don't seem to work
S/PDIF output has been switched to ADAT1. This means that the first ADAT output device,
and therefore the first 8 channels in the ASIO application, are no longer available. All
channels and their assignments still exist, but the optical transmitter has been disconnected
from the ADAT and is now fed from the S/PDIF output (channels 25 and 26).
The performance with emagic's Logic is poor
Ensure that 'Alt.ASIO Mode' is checked (RME DIGI Settings, Options). This setting can be
changed on the fly.
16. Troubleshooting
The dialog 'New hardware component found' does not appear:
Remove the optical cables from the DIGI9652 and check whether the optical outputs
light up when the Mac is switched on. If not, the card is either defective or not correctly
inserted in the PCI slot.
The card and drivers have been installed correctly, but playback does not work:
Check whether the DIGI9652 has been selected as current ASIO device.
Playback works, but record doesn't:
Check that there is a valid signal at the input. If so, the current sample frequency is
displayed in the Settings dialog.
Check whether the DIGI9652 has been selected as recording device in the audio
application.
Check whether the sample frequency set in the audio application ('Recording properties' or
similar) matches the input signal.
Check that cables/devices have not been connected in a closed loop. If so, set the card's
clock mode to 'Master'.
