Additional functions
1. Lowpass filter control (LPF)
This control allows you to adjust the lowpass fil-
ter of the bandpass between 50 Hz and 250 Hz.
The control is activated when the X-Over switch
is set to "Bandpass" (see page 14, point 4).
2. Remote control input
This input is used for connecting an optional-
ly available remote control. The remote control
can be used to adjust the volume of the sub-
woofer.
3. Clipping LED
Normally, the Clipping LED is off and only lights
up if the lowlevel Line Input or one of the High-
level Inputs is overdriven.
On (red): One of the analog signal inputs is over-
driven. Reduce the input sensitivity using the
Gain Control until the LED goes out. Instructions
on how to reduce the input sensitivity are de-
scribed on page 15, point 6.
4. Fuse LED
The LED indicates the status of the internal fus-
es.
Off: Fuses are intact.
On (red): The internal fuses are blown. They
may only be replaced by identically rated fus-
es (2 x 30 A) to avoid damage of the amplifier.
Using higher-rated fuses can lead to dangerous
consequential damage!

5. Status LED
The Status LED indicates the operating mode
of the amplifier.
Green:
The amplifier is ready for operation.
Orange:
There is a short circuit at the speak-
er output or a faulty connection. In this case,
check all connections for errors.
Red:
Protection Mode active. A malfunction has
occurred that may have different root causes.
The amplifier is equipped with protection cir-
cuits against over- and undervoltage as well
as overheating. Please check for connecting
failures such as short-circuits or other incorrect
connections. If the amplifier is overheated, the
internal temperature protection will turn off the
signal output until it reaches a safe temperature
level again. If the amplifier does not turn on, it
is defective and needs to be sent to your local
authorized dealer for repair service.
