Front control > Settings > Amplifier > Output > Limiter:
The output level can be limited to a certain power. This is very useful when the output power of the amplifier is
exceeding the maximum power handling capability of the connected loudspeakers. In case of an increasing level
of the applied input signal, the output power will always be limited to the configured value. This way, loudspeaker
damage due to power overload can be avoided. The maximum output power is selectable within a range of 10 Watt
and the maximum output power of the amplifier, and can be adjusted in steps of 5 Watt.
The currently configured limiter setting is depending on the impedance of the connected loads. Therefore, make
sure that the load impedance settings for low impedance outputs are configured correctly between 4 Ohm, 8 Ohm
or 16 Ohm. This configuration is made in the ‘Output type’ setting (the next setting).
Front control > Settings > Amplifier > Output > Output type:
The output type can be selected between 100V and 70V for constant voltage audio systems and 4 Ohm, 8 Ohm or
16 Ohm for low impedance audio systems. Since the output and limiter settings are configured according to this
selected value, it is always very important to make sure that this is correctly configured. Incorrect configuration of
this setting can lead to damage of the amplifier or the connected loudspeakers.
Front control > Settings > Amplifier > Output > Phase reverse:
The phase reverse setting shifts the output signal over a 180 degrees, for applications where reversed phase
between input and outputs is desirable.
Front control > Settings > Amplifier > Output > Clear preset:
Loudspeaker presets can be uploaded to the amplifier. Customized presets can be made, or typical loudspeaker
presets can be downloaded and loaded into the amplifier. Every preset is made and optimized for one specific type
of loudspeaker. This window indicates if any preset is currently loaded. Presets meant for other than the connected
loudspeakers may affect the performance and sound quality in a negative way, while not providing optimal protection.
Clearing the currently loaded preset is done by selecting this option, dialing to clear and pressing it. Note that other
configurations for the corresponding channel (Eg. filters, equalizing, … ) which are separately made from the preset
will remain unchanged.
Front control > Settings > Amplifier > Output > Linking:
Various linking settings (Link input, Link volume and Volume offset) are shown here. These settings allow permanent
linking of both amplifier and line output of the MFA. The linking settings have to be made in the output settings
menu of the line output, and therefore are not accessible in this menu.
Front control > Settings > Amplifier > Priority:
The priority menu allows to enable priority functionality on the amplifier output. The priority setting has various
configurable settings, such as:
Enable:
Selectable between On / Off
Input:
Selectable between Microphone, Module/Line & Dante inputs (if installed)
Threshold: Selectable within a range of -40 dB ~ -70 dB (Default= -60 dB)
Level:
Selectable within a range of 0 dB ~ -70 dB (Default= -6 dB)
Attack: Selectable within a range of 0 and 9999 ms (Default= 100 ms)
Hold:
Selectable within a range of 0 and 9999 ms (Default= 500 ms)
Decay:
Selectable within a range of 0 and 9999 ms (Default= 100 ms)
In case priority is enabled, all playing audio sources will be interrupted upon signal detection on the selected priority
input and only the priority input will be heard. The priority settings should be configured depending on the available
audio signal.
