This function enables to create a specific delay between the input and the output signal. This delay can be used for time
alignment between different loudspeakers in one configuration. It is configurable in meters within a range of 0 meter and
12 meter with a resolution of 0.1 meter / step. Adjustments can be done by selecting it and turning the rotary selection dial.
After the required delay is selected, it can be confirmed by pressing the rotary function dial.
This function will guarantee that the output level adjustable by the fader on the main screen (which is accessible through
user level access) will never exceed a certain value as configured. This gives protection for non-authorized persons when
increasing the volume. It can be adjusted within a range of 0 dB (no restrictions) and -70 dB.
The screen shows a fader with the configured maximum output level indicated above it. When selected, the fader including
the currently configured maximum output level will turn green and the level is adjustable by turning the rotary function dial.
The fader will slide up or down and after the desired value has been selected, it can be confirmed by pressing the rotary
function dial.
When no signal is detected for a corresponding channel, it will be switched automatically to standby mode. The delay time
between the absence of a signal and switching to standby mode can be selected in this screen. It can be disabled (never) or
adjusted within a range of 1 to 10 minutes. The power consumption will decrease when one or more channels are switched
to standby.
The output level for each channel can be limited to a certain power. This
is very useful when the output power of the amplifier is greater than the
maximum power handling of the connected loudspeaker. Independently
of a rising level of the applied input signal, the output power will be always
limited to the set value. This way, loudspeaker damage due to power
overload can be avoided when this setting is made correctly.
Dynamic bass will make a correction depending of the level (volume) in the low frequencies.
This correction will make that music will sound warm and detailed (with true reproduction of low frequencies) at low volumes,
but with increasing level (volume) the low frequencies will be weakened. This will result in less distortion due to reduced low
frequencies at high volumes, allowing the loudspeaker to handle higher sound pressure levels with less distortion.
It can be switched ON and OFF, whereby OFF means that dynamic bass is disabled and ON means that a level dependent
correction in the low frequencies is made.
The phase reverse button essentially flips the waveform on its head. The
positive oscillations are now negative and vice/versa. This is a quick and
easy way to check the phase of your mics and often a simple solution to
a phase problem.
