When using more than one HDSP system, all units have to be in sync, see chapter 15. Else a
periodicly repeated noise will be heared.
13.3 Synchronization
To achieve sample-accuracy between the
ADAT recorder and Hammerfall DSP
while running Cubase, connect the ADAT
sync output with the 9-pin D-type sync
input of the HDSP. The 'Time Code' field
in the Settings dialogue should now show
the same position as the ADAT recorder.
Double-clicking on the Sync button in
Cubase's transport panel will open the
'Synchronization' dialog. Select ASIO 2.0
as the timecode base (under Sync
Source), confirm the dialog with 'OK',
then activate Sync mode by (single) click-
ing on the Sync button.
If synchronization is not working i.e. Cubase does not respond when the ADAT is set to 'Play',
please try the following:
Check the cables
Switch Sync off and on again (in Cubase's transport panel)
Select 'Reset Devices' from the Options menu.
Switch on the ADAT recorder(s) before starting Cubase
Use the BRC as Master and send its word clock to all other devices
Use the Clock Mode ADAT Sync
