6.4 Digital Outputs
The ADI-8 DS 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 at
activated PROCESS BS or DS, 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 PROCESS BS or DS 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 DS can feed up to 4 devices (2 x
ADAT, 2 x TDIF).
The ADAT optical outputs of the ADI-8 DS are fully compatible to all ADAT optical inputs.
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 DS. Carries
the channels 1 to 8. When sending a Bit Split or Double Speed signal, this port carries the
channels 1 to 4.
ADAT AUX
Copy of the data at the MAIN output. When sending a Bit Split or Double Speed signal, this
port carries the channels 5 to 8.
The TDIF-1 connectors of the ADI-8 DS 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
transmitting a Bit Split or Double Speed signal, this port carries the channels 1 to 4.
TDIF AUX
Copy of the data at the MAIN interface. Carries the channels 5 to 8 in Bit Split or Double Speed
mode.
General hints on TDIF operation
TDIF and word clock
When the ADI-8 DS 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 DS has to be connected to
the word clock input of the first (master) recorder. When using more than one recorder a spe-
cial sync cable (Tascam part number PW-88S) is needed.
Emphasis
The TDIF interface and the DA-converters of the ADI-8 DS support Emphasis. Please note
that an Emphasis indication will not be stored or processed on the sound when doing digital
transfers between TDIF and ADAT, because the ADAT standard does not include Emphasis.
