Caution! To avoid a lost of sound pressure make sure that
the crossover frequencies of high- and lowpass are sepa-
rated of 2 octaves when building a bandpass.
That means: If the lowpass signal is adjusted to 320 Hz the hig-
hpass should be adjusted 2 octaves lower on approx. 80 Hz. (1
octave = double frequency or half frequency)
If a subwoofer is connected we recommend to use high-
pass control 10 as variable subsonic filter or turn it
counter-clockwise to 15 Hz to get a subsonic filter.
12 Lowpass control
To adjust the crossover frequency from 40 Hz to 4000 Hz
Lowpass: 40 - 4 kHz
13 Power LED
Shows the operation mode of the amplifier.
14 Protection LED
The red LED indicates malfunctions of the amplifier.
The DARK BLUE amplifiers have several electronic protection cir-
cuits that shut off the amplifier at overheating, overloading, short-
circuit on loudspeaker, low-ohmic mode or defective power supply.
Please check for connecting failures such as short-circuits, wrong
connections and over-temperature.
If the amplifier does not turn on it is defect and has to be send to
your local authorized dealer for repair service. A detailed descrip-
tion of the malfunction and the purchase receipt has to be atta-
ched.
15 Signal outputs
Full range RCA outputs to connect other amplifiers.
