Basic Operation
5.1 The EDIT Encoder
This is a rotary push-button encoder which is used to navigate and control system parameters. In the
main Preamplifier Control mode and Mixer Control mode it selects preamplifier channels and adjusts pa-
rameters. This encoder is also used for controlling the mixer functions and navigating the setup menu.
5.2 The VOL / MUTE (mix)
This push-button encoder is used to control the level of the headphone and control room outputs (if CR
option card is installed). Turing the knob clockwise increases the level in 1dB steps. A single press will
mute the outputs. Pressing it again will un-mute the outputs.
When the headphone level change is enacted, a temporary pop-out window appears on the left side of
the display (if the current display mode is set to display headphone status, this window will already be
displayed). This window shows the headphone source and level. When level adjustment is complete, the
fly-out window automatically disappears. Pressing and holding this knob will enter the m108 mixer.
5.3 The Front Panel Hardware Switches
The labeling convention for these switches is as follows:
UPPERCASE - Preamplifier mode function
lowercase - Mixer mode function
(parenthesis) - Push-Hold function
The four hardware switches between the VOL / MUTE knob and the OLED display enact the following
functions:
•
48V/mute: pressing this switch will turn on the phantom power supply for a selected mic preamp
channel. In mixer mode this switch is used to mute the selected mixer channel.
•
Ø (ribbon mode) / solo: pressing this switch will reverse the signal polarity of a selected mic preamp
channel. Pressing and holding this switch will activate ribbon mic mode. In mixer mode this switch
is used to solo the selected mixer channel.
•
PEAK CLR / (setup): pressing this switch will clear all the peak status indicators across all 8 mic
preamp channels, or pressing and holding this switch will enter the m108 into Setup Menu mode.
•
GROUP / pan: pressing this switch will activate group mode. Pressing and holding this switch while
turning the EDIT knob adds (or subtracts) sequential channels to a group. In mixer mode this switch
is used to enter and exit pan control on the selected mixer channel.
