D&B D80, Manual

Page: 48 / 80

GR/OVL Indicates whether gain reduction (GR) of the
respective channel is active or the respective
channel is overloaded (OVL).
Mains/SMPS Displays the current mains voltage and
frequency, the current mains power
consumption in combination with a power
limiter LED and the current temperature of the
switched mode power supply (SMPS).
9.5.4. Mains current limiter (MCL)
Selecting «Mains current limiter» opens the corresponding
subscreen.
The D80 features a power limiter which serves to limit the mains
current draw whenever the mains current draw threatens to trigger
the circuit breaker.
Limiting is done by reducing the sound levels evenly on all
channels. This ensures that the tonal balance is kept.
The Mains Current Limiter function allows to set the maximum
mains current draw of the device within the range of 95 to 50 % of
the nominal limit.
The Nominal current limit depends on the mains voltage range:
16 A in high range, 30 A in low range
This may be useful when the onsite conditions require two devices
to be operated per phase conductor or if the onsite circuit breaker
is not sufficiently dimensioned.
On/Off
Activates the additional limiter.
Mains
current limit
The maximum mains current draw is defined as
a percentage value of the nominal current
limit, as indicated above and can be set in the
range from 95 % down to 50 % in steps of
5 %.
When the MCL is activated, the defined value is permanently
displayed on the «Power» button on the Home screen.
