Mic Phantom+48V: switch for +48V phantom power for electrostatic microphones on input 1/2.

Make sure this is not turned on while any other source is connected to input 1/2.
|
||||
It might damage the source and/or the maya44 card.
|

Mic/Line input: if switch is on, input jack 1/2 is microphone input (mono), otherwise line input (stereo).

This is not supported by the ESI windows driver.

Digitial output selectors

These switches allow a direct digital routing from the ADCs to the DACs.
|
||||
Each switch determines where the digital input data to one of the DACs comes from.
|
||||
They are not supported by the ESI windows driver.
|
||||
For normal operation, they should all be set to "PCM out".

Possibly some of these control S/PDIF output(s).

If these turn out to be unused, they will go away in later driver versions.

Selectable values for each of the digital output selectors are:

"PCM out" -> DAC output of the corresponding channel (default setting)

"Input 1"...

"Input 4" -> direct routing from ADC output of the selected input channel
