Output Setup tab

The Input Setup tab contains the controls and status indicators for all functions of the analogue outputs and S/PDIF outputs as described in the hardware section.



Line output level is switched between +4dBu and -10dBV nominal by the '+4/-10' radio buttons.


The stereo digital output has a versatile word-length control using TPDF dither or Prism Sound SNS (Super Noise Shaping), and the RCA connector can be switched to operate as either S/PDIF or AES3 as required.  If the sample rate converter (SRC) is configured in the digital output, a separate sync source and sample rate can be selected.


An assignable level control is available, for use as a stereo or surround monitor volume control, which can be assigned to any desired outputs using the row of 'VOL' buttons. The volume control can be adjusted using the mouse, as well as with the front-panel knob.  There is also a mute button and a numerical readout/setting box.  Note that changes to the assignment of the level control can be prevented by engaging the lock button (marked with a key symbol) just above the level control.  When engaged (red) the lock button prevents changes to the level control assignment in order to avoid accidental full-level output. 


Below each stereo output strip is a drop-list control allowing each output pair to be fed either directly from the workstation ('DAW') or from a dedicated low-latency foldback mixer ('Mixer').  Each stereo mixer can mix any of Orpheus' analogue or digital inputs to the output pair, along with the DAW feed, as described in the following section.  The headphone output pair has a third 'Bus' setting which allows it to monitor any of the other output pairs using the row of headphone bus radio buttons.


All outputs have high-resolution peak metering, with overload indication 0.05dB below clipping.
