Output mixers

Orpheus' output mixers are high-quality, versatile stereo digital mixers available at all of Orpheus' outputs (excluding ADAT outputs). The signal processing in Orpheus' mixers is as precise and sophisticated as in a professional digital console.  All coefficients are filtered at sample-rate to minimise unwanted quantization effects such as zipper noise.

In normal operation, Orpheus' output pairs are set in 'DAW' mode, i.e. they output their respective feeds from the DAW software directly - in this case, Orpheus' output mixers are disabled.  By selecting 'MIX' mode for an output pair, the mixer is enabled: its inputs comprise all eight of Orpheus' analogue inputs, the two-channel digital input, plus the respective stereo feed from the DAW software.  Each input has a dedicated fader and pan pot, plus mute and solo buttons and high-resolution level meter.  Input pairs can be designated as 'stereo', wherein a single ganged fader and balance pot are provided, plus a single mute and solo button.  The stereo output also has fader, mute button and high-resolution level meters. 

The output mixers are primarily intended to provide low-latency foldback or monitor mixes incorporating Orpheus' audio inputs in conjunction with feeds from the DAW software - since the mix is performed locally, the delay involved in passing live audio up to the host computer and back is removed.  However, it is also possible to configure the output mixers for general purpose use, where inputs can be mixed to outputs without involving the Host's audio at all.  Having set up such mixes using the Orpheus Control Panel applet, it is possible to use stand-alone mode to retain the mix features with no computer connected.
