If the input format is set to Single, Dual or Quad AES format, the unit will ignore
the message flags and group the AES inputs accordingly.

RS232
-
Displays - and allows access to – the unit’s RS-232 identity code (an address
between
between
0
and
99
). This is used by the remote control software to send specific
messages to specific units. Use
Up
and
Down
to change this address if you are
operating several units in a multichannel set up. The RS-232 control formats
and procedures are covered in more detail in section
and procedures are covered in more detail in section
starting on page 56
IMPORTANT!
When using the Remote Control, each unit in the daisy chain MUST be set to
a different RS-232 address.

connectors. The

If
BNC
is selected, there is no output.
Loop
The unit attempts to lock to
Reference In,
which is
looped through to the
Reference Out
, with no
termination resistor (termination is then about 1k
Ω,
so several units can be daisy chained).

Converts the data on the selected input to single
AES and sends it to
AES and sends it to
Reference Out
.
The data on a Single AES input is copied with no
conversion.
The data on a Dual or Quad AES input is converted
to Double speed Single AES. 176.4kS/s is
converted to 88.2kS/s and 192kS/s is converted to
96kS/s.

The data on a Dual or Quad AES input is converted
to Double speed Single AES. 176.4kS/s is
converted to 88.2kS/s and 192kS/s is converted to
96kS/s.
If
BNC
in
SDIF
mode is selected, the output is AES
clock with no data at the Word Clock rate.
If the input is 4-wire DSD, the data is converted to
SDIF format DSD and sent to the SDIF inputs.
If the input is 4-wire DSD, the data is converted to
SDIF format DSD and sent to the SDIF inputs.
SDIF Ch1
is checked first before the SDIF inputs
are changed to DSD outputs.
IMPORTANT!
In DDC mode, the analogue outputs are generally muted because the units
resources are used to perform a digital to digital conversion. They are not
muted if the input is 4-wire DSD.
