Remote
12
This input is used to connect the included cable re-
mote control. The remote control allows you to con-
trol the volume of the connected subwoofer.
Speaker Output
13
Speaker outputs to connect a subwoofer. The
minimum load impedance must not be lower than
1 Ohm.
Power & Protect LED
14
The power and protect LED indicates the operating
mode of the amplifier.
Green: The amplifier is ready for operation.
Red: A malfunction has occurred. A malfunction
may have different causes as the HELIX
M ONE X is equipped with several pro-
tection circuits. These protections shut
off the amplifier 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 adjustments and over tempera-
ture.
If the amplifier does not turn on it is de-
fective and has to be sent to your local
authorized dealer for repair service. A de-
tailed description of the malfunction and
the purchase receipt has to be attached.
Fuse
15
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 M ONE X is equipped with 3 x 40 Am-
pere fuses.
+12 V
16
Connect the +12 V power cable to the positive ter-
minal of the battery. Recommended cross section:
min. 10 mm² / AWG 8.
REM
17
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 /
car radio. This input needn't to be assigned if the
Highlevel Input is used.
GND
18
The ground cable should be connected to a common
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 lo-
cation on the vehicle chassis i.e. an area which has
been cleaned of all paint residues. Recommended
cross section: min. 10 mm² / AWG 8.
