DITHER (non-latching switch)
This switch is used to select the digital output bit depth, which should be set to match
the receiving device. Pressing the switch steps through the three available bit depths:
24-, 20- and 16-bit. The green LEDs indicate the currently selected bit depth.
LOCK LED
This LED indicates that the internal A/D chips are correctly synchronised to the
external clock signal entering the rear panel Word clock BNC connector. This LED
will only operate when the EXT SYNC switch is engaged on the rear panel (see
below).
DIGITAL OUTPUT REAR PANEL CONNECTIONS
AND SWITCHES
EXT SYNC (Switch)
This switch allows the digital output to be synchronised to an external word clock
source. When the unit is successfully synchronised the front panel LOCK LED will be
lit (see above).
PLEASE NOTE: the expected sample frequency of the incoming wordclock must be
selected (using the CLOCK SELECT switch on the OctoPre front panel) to ensure
correct synchronisation. If for example the OctoPre is set to 48 kHz and the external
word clock is 44.1 kHz the unit will not lock, and the front panel LOCK LED will
not be lit.
OPTO (2 x ADAT™-type ‘lightpipe’ connector)
These connectors provide the ADAT™-type multi-channel digital outputs as
described above.
EXT SYNC (BNC-type connector)
This connector allows the digital converter to be synchronised to an external word
clock source, as described above.
SPDIF (Switch) [AES/SPDIF/ADAT™ interface card
only]
This switch, when engaged, sets the 9-pin D-type digital outputs to the appropriate
voltage level, balance and professional/consumer status bits for SPDIF operation.
When disengaged the digital outputs operate in AES format.
AES/SPDIF (9-pin D-type connector)
[AES/SPDIF/ADAT™ interface card only]
This connector provides the AES or SPDIF format digital outputs. It must be used in
conjunction with a separate conversion cable (not included with the A/D options) as
described above.
