Controlling Microphone Pre-amplifier Settings
Each microphone pre-amplifier may be remotely controlled in
order to set input gain, phantom power, etc. prior to analogue-
to-digital conversion. These settings may be controlled either
from the fader strip or the Central Control Section. Let’s use the
dedicated controls on the channel fader strip:
1. Use the GAIN control to remotely set the microphone
preamplifier gain.
The gain range is normally adjusted from 0dB to 70dB, although
this may vary depending on your hardware configuration.
Please refer to the DALLIS I/O technical data for details.
2. Press the 48V button to select 48V phantom power.
3. Press the high pass filter button to insert an analogue
subsonic filter prior to the A-D conversion.
4. Toggle this button to cycle through the filter roll-off
frequency options: Off, 40Hz, 80Hz and 140Hz.
The button changes colour to indicate the selected frequency -
green (40Hz); yellow (80Hz); red (140Hz).
5. Press PAD to insert the 20dB PAD.
