Setting a mic amplifier’s input gain
The XL8 Control Centre has two input gains per channel, one is the remote gain for the
DL431 mic box (stage box gain) and the other is the digital trim (console gain); see
“Mic amp - preliminary input processing” on page 38. All of the input gain sections
(control surface and input GUI screen) are interchangeable so that you can swap
control from stage box gain to console gain, and vice versa. This is useful if you want
to change the gain of more than one channel in a bank. By pressing the
gain swap
button, you can select the type of gain you want to the input fast strips and adjust them
there via their gain control knobs.
To set stage box gain/console gain
1
1
Select stage box-type input gain control to the
input fast strips by pressing gain swap .
2
Adjust the gain trim control knob (in 2.5dB steps
from -2.5dB to +45dB) to required level to suit
Midas pre-amp characteristic; see “Operating the
control knobs” on page 18. A suitable level could
be one that only just illuminates the yellow LEDs.
3
Drive the mic amps for that ‘Midas colouration’;
feel free to overdrive if you want.
4
After you have achieved the required gain state,
swap back to the console gain display by pressing
gain swap again.
5
Adjust console digital trim (gives ±20dB
continuous trim) for preferred gain structure.
Please note that the control knob in the input
channel strip (as indicated) always controls the
alternative ‘swap’ to the ones in the input fast
strips.
6
Set analogue remotes for initial set-up, then
adjust digital trim for showtime.
