Input & Pan Parameters
Input and pan parameters are available for all sources. The exact parameters depend on the format of the
source (mono or stereo), and how it is connected (via a mic preamp or line/digital).
Ø
To access input and pan parameters, press an
ACCESS
key followed by
INP
on the Central Module.
When adjusting input gain, use the input meter (on VisTool) to help set a good input level. If the meter (or
signal present indicator on the fader strip) turns red repeatedly, then the input level is overloading and you
should reduce the Mic gain (or channel Gain) value.
MIC Sources
Surface Controls
VisTool
For a mono MIC source, you can adjust input parameters in the analog domain (before the A-D converter) AND
in the digital domain (after the converter).
The analog (mic preamp) section includes:
·
MIC
- mic preamp gain from +18dB (or -2dB with PAD) to +73dB. See also
·
48V
- 48V phantom power.
·
PAD
- 20dB PAD (reduces the mic gain by 20dB). When the PAD is active, the
MIC
gain value
updates accordingly.
·
RUMBLE
- a high pass ‘rumble’ filter to roll-off subsonic frequencies. The rumble filter operates at
80Hz.
In the digital domain, you can also adjust:
·
PHASE
- phase reverse.
·
GAIN
- channel gain from -30dB to +18dB.
·
PAN
- left/right panning onto the stereo buses. (This parameter is not shown on VisTool).
MIC
gain, channel
GAIN
and
PAN
can also be adjusted from the fader strip rotary control (as described
).
