DTRS Multichannel Tape Machines
Although the DA-88/38/98 and 78HR differ in some ways, any one of
them can be connected to the PCI-822 via a single TDIF cable.
If you want the tape machine to be the clock master (set to Internal),
set the PCI-822 clock source to ‘TDIF’ (in the Clock/Device Status tab
of the PCI-822 control panel).
If you want the PCI-822 to be the clock master, set its clock source to
‘Internal,’ and connect a 75-ohm word clock cable from the PCI-822
word clock output to the word clock input on the DTRS tape machine.
Then press the CLOCK button on the tape machine (or WORD SYNC on
the DA-38) to set the clock source to WORD.
If either of the two sample rate indicators on the tape machine blinks,
then your tape is formatted at a different sample rate than the
incoming clock source. Either change the sample rate on the
computer, or use another tape.
To record digital input on the DTRS machine, press the DIGITAL IN
switch. Other features of the DA-98 and DA-78HR, such as input
routing and SPDIF I/O, are covered in their owner’s manuals.
Any of these multitrack tape machines can also be used as either an
8-channel A/D or an 8-channel D/A converter by setting it to monitor
its analog (for A/D) or digital (for D/A) inputs. Unfortunately, you
cannot use both the A/D and D/A converters simultaneously.
