inputs 3&4. The mic selection indicators change from green to orange to indicate that phantom
power is switched on. See
· Master indicator: this is lit when the device is sample clock master (from the FireWire bus point of
view). If a device is configured to be clock master, but is itself slaved to a wordclock or DI
reference which is absent or at a different frequency from the selected sample rate, the master
indicator flashes. For more information see the
· Meter input/output indicator: shows whether the ten bar-graph meters are assigned to the analogue
and S/PDIF inputs, or to the analogue and S/PDIF outputs. This is selected in the
Panel
applet. See the
· Overkiller indicators: indicate that the
Note that the indication is dynamic, and shows when the Overkiller is actually limiting, and not
simply that it is enabled. Note that the Overkiller indicators are only active when the meters are in
input mode.
· DI unlock indicator: indicates that the S/PDIF input is unlocked, i.e. no S/PDIF carrier is recognised.
Only active when the meters are in input mode.
· SRC indicator: shows that the SRC (sample-rate converter) is
when the meters are in input mode) or is
in output mode.

Rear panel
Orpheus' rear panel contains all Orpheus' connections, except for the instrument inputs and
headphone outputs, which are on the
From left to right (viewed from rear):
· 6A IEC inlet (regional power cord supplied): adjacent is the mains
· Two FireWire 400 (IEEE1394A) connectors (4-pin and 6-pin FireWire cables supplied). These
have identical function; either can be used to connect to the host computer, the other can be used
to daisy-chain additional Orpheus units if required. See
· MIDI in and out/thru DIN sockets.
· Wordclock input and output BNC sockets: the wordclock output can supply base-clock or 256x
clock if required. See the
· S/PDIF input and output RCA sockets: these can also be operated as AES3 interfaces (RCA-XLR
and XLR-RCA adapter cables supplied). See
· TOSLINK input and output: can be used for S/PDIF (up to 192kHz sample rate) or ADAT
(44.1kHz/48kHz or 88.2kHz/96kHz in SMUX mode). See
· Line output TRS jacks 1-8: switchable +4dBu/-10dBV level, can operate in balanced or unbalanced
mode. See
