Channel Status; Jumper Options - Prism Sound ADA-8XR Module Reference

Prism Sound ADA-8XR Multi-channel A/D D/A Converter Module Reference - Revision 1.01
The only way to achieve full eight-channel I/O in Split96 mode is to enable Cascade Split96
mode.
When Split96 mode is active for a module, the 'Split96' LED for its DIO slot in either the
'Source' or 'Dest' box of the Mimic Panel will illuminate. If the LED flashes, this indicates that
Split96 mode has been selected, but is not active, usually because the Path is not operating
at an extended sample rate.

5.10 Channel Status

The AES3 I/O Module is tolerant of the Channel Status information embedded within each
incoming AES3 or S/PDIF carrier - in most cases the audio path will not be disrupted even if
the Channel Status information is incorrect or inconsistent.
The only field in the input Channel Status respected by the ADA-8XR is the indication of pre-
emphasis. If an input channel has pre-emphasis indicated, that indication will be passed
through to the corresponding output channels for that path, although how that indication is
acted upon depends on the type of output module. In general, digital output modules re-
transmit the appropriate pre-emphasis information whereas analogue output modules perform
appropriate de-emphasis if possible.
Channel Status for the AES3 outputs is generated locally (with the exception of pre-emphasis
indication) according to the Encode settings for the Path to which the outputs are assigned.
Thus the Channel Status accurately reflects the attributes of the output audio data (sample
rate, wordlength etc.) regardless of the accuracy of any relevant input Channel Status to the
Path. Pre-emphasis is indicated on an output stream only if the corresponding input has such
an indication.
The AES3 I/O Module can generate either Professional or Consumer (AES3 or S/PDIF)
standard Channel Status, as set by the relevant Digital Output Channel Status menu in the
DEST Access group. The table in section 5.12 shows the settings of the Channel Status fields
in each case.

5.11 Jumper Options

There are a number of jumpers on the AES3 I/O Module that are used to set the
characteristics of the inputs (impedance) and outputs (impedance, voltage, grounding). The
user may configure each input and output carrier independently to handle either AES3 or
S/PDIF carriers. The position of the relevant jumpers is shown in the diagram below.
