Smart highlevel input
The latest generation of OE car radios incorpo-
rates sophisticated possibilities of diagnosing the
connected speakers. If a common amplifier will be
hooked up failure messages and loss of specific
features (e.g. fader function) quite often appears -
but not with the G ONE.
The new ADEP circuit (Advanced Diagnostics Error
Protection) avoids all these problems without load-
ing the speaker outputs of the OE radio during high
volumes unnecessarily.
Start-Stop capability
The switched power supply of the HELIX G ONE
assures operation even if the battery’s voltage
drops down to 6 Volts during engine crank.
Unique Features of the HELIX G ONE
Installation with “Easy Plug Cable”
To simplify installation to an OEM or aftermarket
radio the HELIX G ONE can also be connected us-
ing the optional Easy Plug Cable (EPC 5) which will
supply the amplifier with the loudspeaker signals of
the radio. No factory wires or plugs need to be cut
by using this connection method.
The Easy Plug Cable uses the highlevel inputs
A and B.
Note: Never use the power supply cables of the
Easy Plug Cable. Always directly connect the
screw terminals of this amplifier to your car’s
battery using appropriate wires.
Connection to an OEM radio is detailed below:
1.
Once the radio has been removed by using the
right tools disconnect the OEM harness from
the radio. Connect the vehicle cable jack con-
nectors of the Easy Plug Cable. You may need
a special ISO-adaptor depending on vehicle
type. In order to verify please check the adaptor
database on the Audiotec Fischer homepage
www.audiotec-fischer.com
.
2.
Connect the cable plugs to the car radio.
3.
Connect the highlevel plug (8-pole connector)
to the appropriate HELIX G ONE input. The
power supply plug (4-pole connector) remains
unused.
Note - Cars equipped with MOST bus:
In cars equipped with MOST bus structure it is man-
datory to unplug the fiber-optic cable from the origi
-
nal radio connector and insert it into the ISO-adap-
tor which has a dedicated recess for this.
