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.

Set A-Selto Off to disable automatic input selection.

RS232

Displays - and allows access to – the unit’s RS-232 identity code (an address 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 “RS-232 Remote Control Interface” 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.

Ref In

Displays and sets the mode of the AES Reference In/Out connectors. The options are:

Route	Reference Out (connected in parallel with
	Reference In – beware!) is internally driven with
	the selected AES input signal.
	If the input is Dual or Quad AES, the data on the
	lowest of AES1 or AES3 appears on Reference
	Out.
	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 1kΩ,
	so several units can be daisy chained).
Loop.t	As above, but terminates the input to achieve
	110Ω. Use at the end of a daisy chain.
ddC	Converts the data on the selected input to single
	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.
	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.
	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.
