1 Fuse
The input fuse provides protection against an internal equip-
ment fault. The rating is 100 amperes. In addition, the ampli-
fier must be protected by a further line fuse located in the
vicinity of the battery (max. distance from battery: 30 cm).
2 Connecting the remote lead
The remote lead is connected to the automatic antenna (aeri-
al positive) output of the head unit (radio). This is only activa-
ted if the head unit is switched ON. Thus the amplifier is swit-
ched on and off with the head unit.
3 Connecting the battery cable
Connect the +12 V power cable to the positive terminal of the
battery. Recommended cross section: min. 25 mm
4 Connecting the ground cable
The ground cable should be connected to a central ground
reference point (this is located where the negative terminal of
the battery is grounded at the metal body of the vehicle), or
to a bright bare-metal location on the vehicle chassis, i.e. an
area which has been cleaned of all paint residues.
5/6 Speaker terminals
To connect the speaker cables. See figures on page 7.
Never connect the loudspeaker cables with the car chas-
sis gound. It damages your amplifier. Ensure that the loud-
speaker systems are correctly connected (phase), i.e. plus to
plus and minus to minus. Exchanging plus and minus causes
a total loss of bass reproduction.The plus pole is indicated on
most speakers.
The impedance per channel should not be lower than
2 ohm as overheating could cause a shut down of the amplifier.
7/24 Signal inputs
The DARK BLUE amplifiers have RCA connectors for RCA
cables that can be connected with the pre-amplifier output of
the line-outputs of the headunit or with a pre-amplifier. These
connectors are gold-plated to ensure a better signal trans-
mission.
8 Power LED
Shows the operation mode of the amplifier.
9 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.
10 High pass control for channel 1 and 2
To adjust the crossover frequency from 40 Hz to 4 kHz when
switch 12 is set to HPF.
11 Switch for 4-channel / 5-channel mode
4-channel mode: When head units without subwoofer output are
operated, channel 5 is supplied by the signals from all inputs (7),
2 this means, inputs 24 must not be connected.
.
5-channel mode: The subwoofer channel is supplied indepen-
dently from inputs 7, e.g. by a sub out of the head unit.
12 Switch for highpass / full range channel 1 and 2
13 Bass remote connector
To control the bass level from the driver position.
14/15/22 Level controls for input sensitivity
These controls can be used to match the input sensitivity of
the individual channels to the output voltage of the connec-
ted head unit. These controls are not volume controls and are
solely intended for the purpose of sensitivity trimming. The
control range extends from 0,2 V to 6 V.
16/18 Frequency range controls for channels 3 and 4
Control 16: To adjust the lowpass filter between 40 Hz and
4 kHz.
Control 18: To adjust the highpass filter between 10 Hz and
2,5 kHz.
When switch 20 is set on LP/BP, both controls (16 and 18)
can be used to adjust the bandpass.
Caution! To avoid a loss of sound pressure make sure
that the crossover frequencies are seperated by 2 octa-
ves when adjusting the bandpass.
That means for example: When the lowpass signal is adjusted
to 1 kHz, the highpass should be adjusted 2 octaves lower to
250 Hz.
(1 octave = double frequency or half frequency))
17 Bassboost control
To raise the bass signal from 0 to 18 dB at 45 Hz.
dB
variable
Hz
20 30 45 100 200 300 500
0 dB 18 dB
18/16 Frequency controls for channels 3 and 4
(see 16)
19 Phase control for channel 5
This control enables the phase of the bass signal to be shif-
ted by 180° in order to achieve optimum delay equalization
with the other channels.
20 Switch lowpass / bandpass, highpass and
full range channel 3 and 4
21 Frequency range control for subsonic filter
The use of the adjustable subsonic filter (10 - 50 Hz) relieves
the amplifiers as well as the subwoofer by eliminating unrepro-
ducable frequencies.
22 Level control for input sensitiivity
(see 14)
23 Frequency control channel 5
To adjust the frquency of subwoofer channel 5.

WARRANTY REGULATION

Due to the high quality standard Helix products achieved an excellent
international reputation. Therefore we grant a warranty period of
2 years.
The products checked and tested carefully during the entire produc-
tion process. In the case of service note the following:

cellation of sale, compensation for damages or subsequential
damages, are excluded. The warranty period is not altered by the
fact that we have carried out warranty work.
3) Unauthorized tampering with the product will invalidate this war-
