Hardware Configuration - HELIX ULTIMATE P SIX DSP User Manual

Hardware configuration

Configure the HELIX P SIX DSP ULTIMATE as
follows
Caution: Carrying out the following steps will re-
quire special tools and technical knowledge. In or-
der to avoid connection mistakes and / or damage,
ask your dealer for assistance if you have any
questions and follow all instructions in this manual
(see page 17). It is recommended that this unit will
be installed by an authorized HELIX dealer.
1. Setting the input voltage range ("Voltage
Range") of the analog signal inputs
ATTENTION: When using the analog in-
puts (lowlevel & highlevel) as signal in-
put, it is mandatory to adjust the "Voltage
Range" to the output voltage of the signal
source before the first start up in order to
avoid damage to the amplifier.
At first, the "Voltage Range" of the analog in-
puts has to be set inside the device. Remove
the bottom plate by loosening the 10 Allen
screws. Now you have access to the jumpers
(see fig. 1). Each jumper sets the value range
for the corresponding input channels (J1 –
channel A - D and J2 – channel E - F).
If you want to connect a conventional OEM or
aftermarket radio as signal source, the jumper
must be set to "Low Voltage Range" (Line 1 -
4 V / Highlevel 4 - 16 V). This range is preset by
default, see fig. 2.
If you want to connect a factory-installed am-
plifier as signal source, we recommend to de-
termine its maximum output voltage previously
with a suitable measuring device or to contact
your authorized HELIX dealer. If you are not
sure, we recommend to set the jumper to "High
Voltage Range" (Line 2 - 8 V / Highlevel 8 -
32 V) to avoid possible damage to the device.
Therefore, both jumpers have to be reposi-
tioned to the factory unused multi-pin connec-
tor, see fig. 3.

Jumper 1 (J 1): Channel A - D
Jumper 2 (J 2): Channel E - F
For repositioning a jumper simply pull it up-
wards and plug it into the desired plug posi-
tion.
Make sure that the jumper is reinserted prop-
erly and all pins are fully inserted.
