Prism Sound Orpheus
using the Orpheus Control Panel applet, it is possible to use
features with no computer connected.
For more information, see the
Stability and latency
section.
5.1.6
Assignable level control
Orpheus' front panel has a large assignable level control. This control can be assigned individually to
any of Orpheus' analogue of digital outputs (excluding the ADAT outputs, and the headphone outputs
which have their own dedicated level controls). Operation of the front panel control fades all assigned
outputs. The setting of the control is indicated by a halo of LEDs around the knob. The assignable
level control is primarily intended to implement stereo or surround control-room monitoring systems.
Assignment is via the
Output Setup tab
an indication of the position of the control, which can also be operated on the screen using the
mouse.
5.1.7
Headphone outputs
The headphone outputs signal path differs from Orpheus' other output signal paths in a couple of
respects.
Firstly, the 'DAW'/'MIX' switch has a third 'BUS' position in the case of the headphones. This means
that as well as outputting the DAW headphone feeds directly ('DAW'), or outputting a mix of inputs
plus the DAW headphone feeds ('MIX'), the headphone outputs can be switched across any of the
other output pairs (except for the ADAT outputs). In the
Panel
applet, just above the 'DAW'/'MIX/'BUS' selectors is a row of radio buttons for selecting which
output pair is monitored by the headphone outputs in 'BUS' mode. Note that the headphone
monitoring point of the outputs is before the application of the assignable gain control (if assigned).
Second, the headphone outputs cannot be assigned to the assignable gain control. This is because
they already have dedicated volume controls on the front panel.
5.1.8
Metering system
Orpheus' front panel meters can meter the level of either inputs or outputs as selected in the
Settings tab
of the
Orpheus Control Panel
allows the input/output mode of all front panel meters in a multi-unit system to be switched
simultaneously. The left-most eight meters show the levels of the eight analogue inputs (or outputs);
the right-most two meters show the level of the S/PDIF inputs (or outputs). The bar-graphs change
colour progressively from blue, through green to orange as signal level increases. A red 'overload'
LED is lit if the signal reaches -0.05dBFS. Each of the eight analogue meters has an indicator
beneath which shows when the
input.
Within the Orpheus Control Panel applet, the
and two S/PDIF inputs (as per the front panel, including Overkiller indicators), and the
tab
shows the levels of the eight analogue and two S/PDIF outputs (as per the front panel) plus the
headphones level. The
ADAT tab
shows the levels of all eight ADAT send and return channels.
