The desired digital input format is selected in the 'D-D Mode Setup' menu. See
sections 4.6 and 4.7.
Note on Split96 operation: 'Split96' is a format for passing hi-sampled (88.2kHz or 96kHz) signals on AES3 or
AES-3id carriers at conventional bit-rates. This is achieved by using a single AES3 carrier per hi-rate channel
(it would normally carry a stereo channel). This format has the advantage that conventional, low-rate,
multichannel storage media can often be used to record 88.2kHz or 96kHz data. The format is described in
[Ref.8].
6.3. Digital output connectors
The AD-2 Dual-rate A/D converter can generate digital audio outputs in a variety of
formats. These are:
AES3 professional AES/EBU on an XLR connector;
AES3 'Split96' professional AES/EBU on two XLR connectors, one per
channel at 88.2kHz or 96kHz sample rates;
AES-3id professional AES/EBU on a BNC connector;
AES-3id 'Split96' professional AES/EBU on two BNC connectors, one per
channel at 88.2kHz or 96kHz sample rates;
IEC958 consumer on an RCA/phono connector;
Optical consumer on a TOSLINK connector;
SDIF-2 professional on two BNC connectors plus wordclock;
DSD* one-bit data stream on two BNC connectors plus clock,
subject to an upgrade option
Two female XLR digital output connectors are fitted, which are used for either AES3 or
Split96 operation.
Three BNC digital output connectors are fitted, two of which are used for either
AES-3id, Split96, SDIF-2 or (with upgrade option) DSD operation. The third BNC is a
wordclock output for use with the SDIF-2 output, or simply as a reference sync to other
equipment. The wordclock connector doubles as a DSD clock output in that mode.
IEC958 (phono) and optical output connectors are dedicated, single function.
The format and path assignment (Main or Aux) for each digital output connector is
selected in the 'Digital Output Assign' menu, as described in section 4.6 and 4.7.
