The above-described settings can be accepted or modi-
fied as required. The unique unit design with its PCB
gold-plated on both sides,the consistent employment of
carefully selected high-end components, mechanical
components of uncompromising quality and a switched
power pack for controlled power supply guarantee
maximum audible enjoyment of the highest standard -
without loss and without distortion.
In order to facilitate easy operation of the HXE 100 after
installation, the frequently employed controls and swit-
ches have been located on the front panel.To extend the
controls for easy operation,press them gently and allow
them to protrude. Once the adjustment has been made,
press them again and they will be returned to their flush
position so as to prevent any accidental maladjustment.
The other controls required for the basic settings are
concealed for the same reason. The controls for adju-
sting the cutoff frequencies can be adjusted with ease
from the front using the enclosed screwdriver.The indi-
vidual input gain controls are adjusted from above so
that,at full loudness volume of the HXE 100 (Note! 7 volt
output), the downstream components, and particularly
the speakers, still remain undamaged.
The ILL switch enables the color of the unit illumination
to be changed from green to amber.This allows the unit
to be adapted to virtually any vehicle interior.
Installation
In order to be able to operate the HXE 100 with ease,
install it at a location which ensures good visibility and
accessibility.Make sure that it is firmly fastened in posi-
tion (using the enclosed fixing materials) and that there
is sufficient space for connecting the cables to the rear
of the unit.In addition,the HXE 100 should not be instal-
led too close (leave at least 15 cm) to sources of inter-
ference such as the ignition coil. As the unit does not
require any special cooling, it can be located where
space is tight, subject to the above conditions being
met.
Before commencing the electrical connection work,dis-
connect the negative terminal of the vehicle battery and,
where appropriate,the negative terminals of the ignition
system condensers. Now connect the black wire of the
power supply plug to the common ground (chassis)
connection of the car radio. The red wire provided with
a fuse should be connected to a steady positive + 12
Volt pole. Connect the remote wire to the antenna plus
(aerial positive) output of the radio. Then connect the
plug to the appropriately marked power input socket.
The signal connections are standard commercial cinch
sockets (RCA). Connect the cinch cables coming from
the car radio to the input sockets marked MAIN. Ensure
that the right and left channels are correctly connected.
Additional devices such as CD changers,Walkman per-
sonal stereos etc., can be connected to the AUX input.
Now connect the outputs to your amplifiers (front panel
output to the front amplifier,rear panel output to the rear
amplifier). If you have a separate amplifier for your sub-
woofer,connect the subwoofer output (SUB Output) to it.
In order to avoid ground leakage, ensure that the exter-
nal contacts of the cinch connector do not touch the unit
chassis.
Settings
Determine the maximum signal output voltage from the
technical documentation relating to your car radio (CD
player etc). Set the individual input gain controllers in
the cover of the unit accordingly.If there are doubts,first
turn these controllers fully counter-clockwise and then
open each channel during system operation until, with
the volume control of the HXE 100 at maximum output,
all distortion is eliminated and all the downstream com-
ponents are properly protected.
The concealed controls for the cutoff frequencies should
first be adjusted using the screwdriver supplied so that
all the channels are identically set at the mid position
(i.e. approx. 45 Hz, 275 Hz, 2.8 kHz, 16 kHz).The asso-
ciated volume controls should also be set to their cen-
tral position,i.e. +/- 0 dB.Set your subwoofer crossover
to the filter frequency required for the subwoofer type
employed (in most cases this will be 60 - 100 Hz). The
volume control should first be turned fully counter-
clockwise (quiet).
