Smart highlevel input
The latest generation of OE car radios incorpo-
rates sophisticated possibilities of diagnosing the
connected speakers. If a common amplier will be
hooked up failure messages and loss of specic
features (e.g. fader function) quite often appears -
but not with the G FOUR.
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 FOUR
assures operation even if the battery’s voltage
drops down to 6 Volts during engine crank.
Unique Features of the HELIX G FOUR
Installation with “Easy Plug Cable”
To simplify installation to an OEM or aftermarket ra-
dio the HELIX G FOUR can also be connected us-
ing the optional Easy Plug Cable (EPC 5) which will
supply the amplier 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 - D.
Note: Never use the power supply cables of the
Easy Plug Cable. Always directly connect the
screw terminals of this amplier 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-scher.com.
2. Connect the cable plugs to the car radio.
3. Connect the highlevel plug (8-pole connector)
to the appropriate HELIX G FOUR 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 ber-optic cable from the origi-
nal radio connector and insert it into the ISO-adap-
tor which has a dedicated recess for this.
