Initial start-up and functions
10
Bass Boost
This control is used to increase the bass response
at a center frequency of 45 Hz from 0 to 12 dB.
11
GND
The ground cable should be connected to a com-
mon ground reference point (this is located where
the negative terminal of the battery is grounded
to the metal body of the vehicle) or to a prepared
metal location on the vehicle chassis i.e. an area
which has been cleaned of all paint residues. Rec-
ommended cross section: min. 16 mm² / AWG 6.
12
REM
The remote lead should be connected to the remote
output / automatic antenna (aerial positive) output
of the head unit / car radio. This is only activated
if the head unit is switched on. Thus the amplifier
is switched on and off together with the head unit.
This input needn’t to be assigned if the
Highlevel
Input
is used.
13
+12 V
Connect the +12 V power cable to the positive ter-
minal of the battery. Recommended cross section:
min. 16 mm² / AWG 6.
14
Fuse
The input fuses are connected in parallel and pro-
vide protection against an internal fault of the de-
vice, therefore the system must be additionally pro-
tected by a further main fuse located close to the
battery (max. distance from battery: 30 cm / 12”).
The HELIX G FIVE is equipped with 3 x 40 Ampere
fuses.
15
Power & Protect LED
The power and protect LED indicates the operating
mode of the amplifier. The LED lights up green
when the amplifier is ready for operation. If the LED
lights up red a malfunction has occurred.
A malfunction may have different causes as the
HELIX G FIVE is equipped with different protec-
tion circuits. These protections shut off the amplifi
-
er in case of overheating, over- and undervoltage,
short-circuit on loudspeakers and false connection.
Please check for connecting failures such as
short-circuits, wrong connections, wrong adjust-
ments and over temperature.
If the amplifier does not turn on it is defective and
has to be send to your local authorized dealer for
repair service. A detailed description of the malfunc-
tion and the purchase receipt has to be attached.
16
Output Channels
Speaker outputs of the channels A - D and SUB to
connect speaker systems and a subwoofer. The
impedance per channel must not be lower than
2 Ohms (4 Ohms channels A to D in bridged mode).
