If the front Led is set to OFF, the limiter active condition turns on the logo
backlight.
4.5.4. Loudness (ALC)
Select ON to put
ALC
in automatic mode, or OFF to disable it. When
ALC
is active,
it will be displayed in the main screen.
ALC
is a DSP algorithm developed by the Research and Development team at
Amate Audio
to improve the listening experience when the cabinet is being used at
low reproduction levels.
Under this listening condition, the behaviour of human ear is to naturally enhance the
level of middle frequencies. The lower the level, the higher is the middle frequency
enhancement. To compensate for that effect,
ALC
applies a correction to the
frequency response of the system.
In order to do that,
ALC
automatically senses the average signal level at the input:
when this level is low, the DSP will apply loudness compensation curves (based on
Fletcher-Munson’s equal loudness contours), that will dynamically adapt the
frequency response of the cabinet to the listening conditions.
This feature will only influence the frequency response when the input signal
average is below 6dB of the nominal input, that is, when the cabinet is performing at
levels below half of its rated program power. In the range between -6dB and 0dB in
respect to the nominal input, the
ALC
will not modify the response.
4.5.5. Mute
Select ON to Mute the amplifier. The MUTE condition will be shown in the main
screen.
4.5.6. LCD Backlight
Select how the backlight of the LCD in the back panel will behave. When set to ON,
the backlight is always active. When set to OFF, works in automatic mode: the
backlight lights up after a key press, and light off after 30 seconds of the last key
press.
4.5.7. Keypad Lock
When set to ON, the Keypad automatically locks after 60 seconds of inactivity. When
set to OFF, Keypad remains always active.
Remember that to unlock the Keypad, the keys MENU and OK must be pressed
simultaneously.
4.6.
