Hardware conguration
Congure the HELIX AMPLIFY 204 DIRECT as
follows
Caution: Carrying out the following steps will
require special tools and technical knowledge. In
order to avoid connection mistakes and / or dam-
age, ask your dealer for assistance if you have any
questions and follow all instructions in this manual
(see page 11). It is recommended that this unit will
be installed by an authorized HELIX dealer.
For better access to the connectors and control
units, we recommend to remove the amplier’s
cover panels, as shown on page 13, g. 2.
1. Adjusting the operating mode
The AMPLIFY 204 DIRECT can be operated
as a 4-, 3- or 2-channel amplier. The two
mode switches (page 12, point 4) are used to
select the desired mode.
The available operating modes are as follows:
Stereo: In this mode, the stereo amplier out-
put (A & B or C & D) is controlled via the corre-
sponding stereo signal input (A & B or C & D).
Mono bridged: In this mode, the stereo ampli-
er output (A & B or C & D) is controlled via
one signal input (A or C).
4-channel operation: Both switches must
be set to “Stereo” to operate the amplier in
4-channel mode.
3-channel operation: To operate the amplier
in 3-channel mode (front system + subwoof-
er), the switch of channel pair A/B (front sys-
tem) must be set to “Stereo” and the switch
of channel pair C/D to “Mono Bridged”. The
bridged channel is controlled solely by signal
input C. In this switch position, signal input D
is disabled.
2-channel operation: Both switches must be
set to “Mono Bridged” to operate the amplier
in 2-channel mode. In this mode, only signal
inputs A and C are used, while signal inputs B
and D are deactivated.
2. Connecting the pre-amplier inputs
These four lowlevel line inputs can be con-
nected to signal sources such as DSPs or
DSP ampliers using appropriate cables. It is
possible to optimally adapt the input sensitivity
of each channel pair (A/B and C/D) to the sig-
nal source using the respective Gain control
(page 14, point 4).
3. Connection to power supply & remote
Make sure to disconnect the battery before
installing the AMPLIFY 204 DIRECT.
Ensure correct polarity.
+12 V: Connector for the positive cable.
Connect the +12 V power cable to the posi-
tive terminal of the battery. The positive wire
from the battery to the ampliers power termi-
nal needs to have an inline fuse at a distance
of no more than 12 inches (30 cm) from the
battery. The value of the fuse is calculated
from the maximum total current input of the
whole car audio system (204 DIRECT = max.
70 A RMS at 12 V RMS power supply). If your
power wires are short (less than 1 m / 40”)
then a wire gauge of 10 mm² / AWG 8 will be
sucient. In all other cases we strongly rec-
ommend gauges of 16 - 25 mm² / AWG 6 – 4!
GND: Connector for the ground cable. The
ground wire 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 cleaned of all paint resi-
dues. The cable should have the same gauge
as the +12 V wire. Inadequate grounding
causes audible interference and malfunctions.
REM:
The remote input is used to switch on and
o the amplier. It is mandatory to connect this
input to the remote output of the preconnected
device (DSP or DSP amplier) that provides
the input signal to the AMPLIFY 204 DIRECT.
We do not recommend controlling the remote
input via the ignition switch to avoid pop noise
during turn on / o.
4. Adjustment of the input sensitivity
ATTENTION: It is mandatory to properly
adapt the input sensitivity of the AMPLIFY
2014 DIRECT to the signal source to
achieve the best possible signal quality
and avoid damage to the amplier.
The input sensitivity of each channel pair (A/B
and C/D) can be optimally adapted to the sig-
nal source using the respective gain control
(page 12, point 3).
