1. remove the two screws highlighted in FIGURE 11 with a
Philips screwdriver. The panel will easily separate from the
amplier exposing the sponge-like air lters.

1. before replacing the front panel, reposition the air lter on
the chassis by placing it on its designated area
2. reposition and tighten the two frontal screws.
5.3 Front Panel Adjustments
The front panel of all M Series ampliers has one stepped attenuation
knob for each channel. Turning the knob counterclockwise, the
user can select the amplier’s gain value in steps corresponding
to the following values: -∞, 4, 14, 18, 20, 22, 24, 26, 28, 30, 32 dB.
5.4 Front Panel Monitoring
The M Series front panel provides important information on the
state of the amplier. It is important to know and understand the
meaning of every front panel indicator LED in order to have crucial
information on what’s going on and what could be going badly
with the amplier.
There are two sets of LEDs on the M Series front panel. There are
Channel indicators and Status Indicator LEDs. Channel indicators:
each channel has its own column set of 4 LEDs. The top LED
is red, and the following three are green. Status indicators: each
channel pair has one set of two green status indicator LEDs.
The function of both families of LEDs is summarized in the
following chart:

Should the temperature increase beyond 85° C, the LED will stay on and the channel
will be muted. The amplier will resume normal functioning and the LED will turn off
automatically when the temperature falls below 75° C.

5.5 Rear Panel
The rear panel of the M Series with optional DSP has a 4-green-
LED column per channel pair. The LED lights to indicate which
preset is active for that specic channel pair. Preset parameters
are dened, set and modied by connecting the M Series amplier
with optional DSP to a computer running the Armonía Pro Audio
Suite. In case of a 4-channel amplier (MxxQ models), the rst
LED column indicates the selected preset active on channels 1
and 2, while the second column refers to the preset selected
for channels 3 and 4. A signal can be sent remotely to the amp
to force all preset LEDs to blink for 30 s; this can be useful in a
situation where many ampliers are networked together and it is
necessary to identify which amplier responds to which particular
network address.
5.6 Connecting Audio Inputs
5.6.1 MxxD Models
Audio input connections are made via two XLR connectors found
on the rear of the amplier. Signal looping (i.e. link thru) is possible
using the two XLR male connectors which are also found on
the back panel. The Link on/off button allows to connect input
channels 1 and 2 in parallel.
