Input Setup tab

Parent chapter  Previous page  Next page

 

The Input Setup tab contains the controls and status indicators for all functions of the analogue inputs and S/PDIF inputs as described in the hardware section.  Inputs 5-8 handle line-level inputs, whereas inputs 3&4 can operate as mic or line inputs, and inputs 1&2 as instrument, mic or line.  Mode selection is handled automatically depending on which connectors are used.

 

 

Instrument input mode is indicated by the blue 'INST' legend at the top of the strip, microphone mode by the pink 'MIC' legend and line mode by the green 'LINE' legend.  Line input sensitivity is switched between +4dBu and -10dBV nominal by the '+4/-10' radio buttons, whereas mic and instrument input gains are adjusted in 1dB steps by the slider controls, and indicated by the number beneath, which can also be directly entered if required.

 

Overkiller progressive limiters are selectable for each analogue input, with phase-reverse and high-pass filters being available for mic and instrument inputs. Mic inputs have +48V phantom power switchable per-channel. Inputs 1&2 have an RIAA de-emphasis filter selectable as an alternative to the high-pass filter, allowing them to be used with vinyl decks. MS matrixing is available for mic or line inputs 1-4, allowing use of mid-side microphone configurations.

 

The DI strip can be switched between RCA and TOSLINK S/PDIF inputs, and UNLock and ASNC indicators are provided.  UNLock is lit when no S/PDIF carrier is detected at the selected input; ASNC (asynchronous) is lit when the incoming carrier is not locked to Orpheus' selected sync source.

 

All inputs have high-resolution peak metering, with overload indication 0.05dB below clipping; the analogue input meters also have Overkiller-active indicators which light dynamically when the Overkillers are limiting.
