Input
Input parameters are available for every source. The exact parameters vary depending on whether the source is
mono, stereo or surround and its input type: mic, line-level or digital.
Mono Sources
For microphone sources, the available parameters are:
·
Mic
- analogue mic preamp gain from +0dB (or -20dB with PAD) to +70dB. See also
·
48V
- 48V phantom power.
·
Phase
- phase reverse.
·
Pad
- a 20dB PAD (gain reduction); the mic gain value updates accordingly.
·
Rumble
- a high pass ‘rumble’ filter to roll-off subsonic frequencies before the A-D converter (the rumble
filter can be set to 40Hz, 80Hz or 140Hz, using the rotary encoder).
·
Gain
- digital gain from -30dB to +18dB.
·
Pan
- left/centre/right panning applied to stereo or surround summing bus assignments.
For a line-level or digital source, there is no mic preamp and so the available parameters are:
·
Phase
- phase reverse.
·
Gain
- digital gain from -30dB to +18dB.
·
Pan
- left/centre/right panning applied to stereo or surround summing bus assignments.
You can use the fader strip rotary control to adjust other pan parameters such as front/rear pan, LFE level,
etc.
Stereo Sources
For stereo sources, the available parameters are:
·
Phase
- phase reverse for the left input.
·
Stereo
- turn the rotary control to select the input mode:
o
Stereo
= normal left/right operation
o
ms-> xy
= ms decoding for a middle & side signal.
·
l->b
- routes the left input to both sides of the stereo channel.
·
r->b
- routes the right input to both sides of the stereo channel.
·
mono
- sums the left and right inputs and applies a -3dB gain offset.
·
side
- reverses the left and right inputs.
·
Gain
- digital gain from -30dB to +18dB.
·
Basis
- left/right width.
·
Bal
- left/right input balance.
