1 Connecting the remote lead
The remote lead is connected to the automatic antenna
(aerial positive) output of the head unit (radio). This is only
activated if the head unit is switched ON. Thus the ampli-
fier is switched on and off with the head unit.
2 Connecting the ground cable
The ground cable should be connected to a central ground
reference point (this is located where the negative terminal
of the battery is grounded at the metal body of the vehicle),
or to a bright bare-metal location on the vehicle chassis, i.e.
an area which has been cleaned of all paint residues.
3 Connecting the battery cable
Connect the +12 V cable to the positive terminal of the bat-
tery. Recommended cross section: min. 10mm

.
4 Fuses
The input fuses are connected in parallel and provide pro-
tection against an internal equipment fault, i.e. the system
must be additionally protected by a further line fuse loca-
ted in the vicinity of the battery (max. distance from bat-
tery: 30 cm). The fuse ratings are 2 x 25 amperes, and both
must be installed as the amplifier protection rating is 100
amperes (2 x 25 A).
5 - 7 CPS (Color Protection System)
The LEDs show the operation status of the amplifier.
Blue (No. 5) = on, Yellow (No. 6) = malfunction of ampli-
fier. E.g., battery voltage lower than 8,5 V or over 16 or,
speaker wires are shorted to the ground)
Red (No. 7) = the amplifier has shut off due to overheating.
In this case it will take some time (depending on outside
temperature) until it switches on again.
8 - 9 Signal inputs
The H 1000 ESPRIT has RCA connections for cinch cables
leading from the pre-amplifier outputs, the line outputs of
the head unit or the outputs of a pre-amplifier/equalizer,
e.g. HXE 100. These connections are gold-plated in order
to ensure better signal transmission.
10 Mono/stereo input signal selector
For stereo operation (two cinch leads) the switch has to be
in position B (stereo), both inputs (8 and 9) are occupied.
For mono operation only input 8 is occupied and the switch
is in position A (mono).
11 Add-on subsonic filter
If reqiured an additional subsonic filter (26Hz/30dB/oct
can be switched on.
Position A: subsonic filter off
Positiong B: subsonic filter on
12 Speaker connection terminals
The impedance minimum of all connected speakers must
not be lower than 2 ohms.
Attention!
When tuning bass reflex systems, this value will soon be
fallen below. Please check with the maker of your subwo-
ofer. When using bass reflex systems we suggest to have
the subsonic filter (switch 11, position B) switched on.
Important notice!
Never connect the speaker cables to the vehicle ground
(chassis). This can destroy your amplifier.
13 Level controls for input sensitivity
These controls can be used to match the input sensitivity to
the output voltage of the connected head unit. These con-
trols are not volume controls and are solely intended for the
purpose of sensitivity trimming. The control range extends
from 600 mV to 8,0 V.
14 Damping factor control
For individual sound tuning the damping factor can either
be raised (more bass) or lowered (balanced and warm).
15 Operation mode selector switch
Position A: The amplifier works linear, the integrated
active
frequency cross over and the parametric equalizer are
switched off
.
Position B: The input signal is sent to parametric equalizer
and can be adjusted with the controls 16 - 19.
Position C: The input signal is sent to the parametric equa-
lizer and to the active frequency crossover and can be adju-
sted with the controls 16 - 19, the switch 20 and the con-
trols 21 and 22.
Parametric equalizer
With its integrated highly innovative parametric equalizer
