Protection Led; Signal Outputs; Warranty Regulation - HELIX Dark Blue Instruction Manual

Caution! To avoid a lost of sound pressure make sure
that the crossover frequencies of high- and lowpass are
separated of 2 octaves when building a bandpass.
That means: If the lowpass signal is adjusted to 320 Hz the
highpass 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

14 Protection LED

The red LED indicates malfunctions of the amplifier.
The DARK BLUE amplifiers have several electronic protection
circuits 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
description of the malfunction and the purchase receipt has
to be attached.
