Digital Inputs - RME Audio ADI-8 PRO User Manual

6.3 Digital Inputs

The ADI-8 PRO provides two digital inputs, both in ADAT optical and TDIF-1 format. In
normal operation only the MAIN inputs are used. When using more than the first 4 channels
PLUS activated COMBINE the AUX inputs also have to be used.
The key DIGITAL INPUT sets the desired input active.
The ADAT optical inputs of the ADI-8 PRO are fully compatible with all ADAT optical out-
puts. RME's unsurpassed Bitclock PLL prevents clicks and drop outs even in extreme vari pitch
operation, and guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK
cable is sufficient for connection.
ADAT Main
Interface for the first or only device sending an ADAT signal to the ADI-8 PRO. Carries the
channels 1 to 8. When receiving a Bit Split signal this port carries the channels 1 to 4 (split into
16 bit and 8 bit).
ADAT AUX
Only necessary in COMBINE mode. Interface for the second device sending a Bit Split signal
to 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 with all devices offering
such an interface, for example DA-38 and DA-88. A low jitter PLL ensures best playback sound
quality and reliable operation. RME's exclusive SyncCheck verifies synchronous operation
when using both TDIF ports. 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
receiving a Bit Split signal this port carries the channels 1 to 4 (split into 16 bit and 8 bit).
TDIF AUX
Only necessary in COMBINE mode. Interface for the second device sending a Bit Split signal
to 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.
