Digital Outputs - RME Audio ADI-8 PRO User Manual

6.4 Digital Outputs

The ADI-8 PRO provides two digital outputs, both in ADAT optical and TDIF-1 format. In
normal operation only the MAIN outputs are used. When using more than the first 4 channels
PLUS activated COMBINE the AUX outputs also have to be used.
TDIF and ADAT optical outputs always operate simultaneously and carry the same audio data.
As long as BIT SPLIT isn't activated MAIN and AUX also operate simultaneously and carry the
same audio data. With this it is possible to distribute the output signal to two devices of the
same format. When using all connectors the ADI-8 PRO is able to feed up to 4 devices (2
x ADAT, 2 x TDIF).
The ADAT optical outputs of the ADI-8 PRO are fully compatible to all ADAT optical in-
puts. A usual TOSLINK cable is sufficient for connection.
ADAT Main
Interface for the first or only device receiving an ADAT signal from the ADI-8 PRO. Carries
the channels 1 to 8. When sending a Bit Split signal this port carries the channels 1 to 4 (split
into 16 bit and 8 bit).
ADAT AUX
Copy of the data at the MAIN output. In BIT SPLIT mode: Interface for the second device re-
ceiving a Bit Split signal from the ADI-8 PRO. Carries the channels 5 to 8 (split into 16 bit
and 8 bit).
The TDIF-1 connectors of the ADI-8 PRO are fully compatible to all devices with such an
interface, for example DA-38 and DA-88. The connection is done through a special TDIF cable,
available at your local dealer (Tascam part number PW-88D).
TDIF Main
Interface for the first or only device with a TDIF-1 interface. Carries the channels 1 to 8. When
sending a Bit Split signal this port carries the channels 1 to 4 (split into 16 bit and 8 bit).
TDIF AUX
Copy of the data at the MAIN interface. In BIT SPLIT mode: Interface for the second device
receiving a Bit Split signal from the ADI-8 PRO. Carries the channels 5 to 8 (split into 16
bit and 8 bit).
General hints on TDIF operation
TDIF and word clock
When the ADI-8 PRO is slave no additional word clock connection is necessary. In case
DA88 and/or DA38 are slave the word clock output of the ADI-8 PRO has to be connected
to the word clock input of the first (master) recorder. When using more than one recorder a
special sync cable (Tascam part number PW-88S) is needed.
Emphasis
The TDIF interface and the DA-converters of the ADI-8 PRO support Emphasis. Please
note that an Emphasis indication will not be stored or processed on the sound when doing digi-
tal transfers between TDIF and ADAT, because the ADAT standard does not include Emphasis.
