Front control > Settings
The settings menu is accessed through pressing the settings (lower) button on the main screen. This menu includes
all the settings regarding the inputs, amplifier output, line output and general system settings. Specific settings
regarding the installed modules are found in the module control menu.
Front control > Settings > Inputs
The input settings menu includes a 7-band parametric equalizer for both microphone and line (Line / module)
inputs. It allows to cut or boost specific frequency ranges.
A standard configuration with center frequencies for 60 Hz, 150 Hz, 400 Hz, 1 kHz, 2.6 kHz, 6.8 kHz and 15 kHz
with Q factor of 0.7 is pre-loaded. The center frequency of each band can be continuously adjusted within a range
of 10 Hz and 22 kHz, while the Q-factor can be adjusted within a range of 0.1 and 9.9 and the level of each band
within a range of +15 dB and -15 dB.
A fader overview for the 7 bands equalizer will be shown when selecting the corresponding input. On top of the
screen, the center frequencies for each band are shown on top of the currently set levels. The selection of the
corresponding band is done by turning the rotary selection dial until the corresponding band is highlighted and
pressing it. Level adjustment can be done by turning the selection dial and confirmed by pressing it again. After
this confirmation, another band can be selected and adjusted the same way.
Adjustment of the center frequencies and Q-factors is done through pressing the ‘Freq’ and ‘Q’ buttons on the
side. When selected, a pop-up window will appears where the corresponding adjustments for each band can be
made. Adjustment of center frequencies is done by selecting the adjusting digit (highlighted) and confirming. The
value will increase or decrease through rotating the rotary selection dial. Consecutive digits will increase when the
maximum value is reached. After the desired frequency has been selected it can be confirmed by pressing and
turning the function dial clockwise until ‘OK’ is highlighted.
Q-factors are changed by selecting and turning clockwise (up) or counter-clockwise (down). This confirmation
can be done by pressing again.
Front control > Settings > Amplifier
The amplifier settings menu leads you to a separate menu where the settings for the amplified output can be made.
Front control > Settings > Amplifier > Mute:
Muting will completely suppress the output signal. The mute indicator will indicate in green when the channel is
playing and turns red when muted. Toggling between both states can be done by pressing the rotary function dial
once.
Front control > Settings > Amplifier > Filter:
Filters are frequently used in audio systems for different purposes. Some typical application examples are filtering
noise or other unwanted signals from an audio signal and separating audio signals between different frequency
ranges (crossover) when a 2-way (or more) system is used.
Because the characteristics of the required filter are strongly dependent of the application, the filter settings are
made flexible and user configurable. Characteristics which can be configured for the filters are:
