1 Connecting the ground cable
The ground cable should be connected to a central
rence point (this is located where the negative terminal of the bat-
tery 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.
2 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 amplifier is switched on
and off with the head unit.
3 Connecting the battery cable
Connect the +12 V power cable to the positive terminal of the
battery. Recommended cross section: min. 25mm

4 Fuses
The input fuses are connected in parallel and provide protection
against an internal equipment fault, i.e. the system must be addi-
tionally protected by a further line fuse located in the vicinity of
the battery (max. distance from battery: 30 cm). The fuse rating
for ESPRIT E40 is 4 x 15 amperes.
5 Power LED
Shows the operation mode of the amplifier.
6 Signal inputs CH 1 + CH 2
The ESPRIT amplifiers have RCA connectors for RCA cables that
can be connected with the pre-amplifier output of the line-outputs
of the headunit or with a pre-amplifier. This connectors are gold-
plated to ensure a better signal transmission.
7 High- and low level signal switch CH 1 + CH 2
To change the input signals from low level (head unit or pre-
amplifier) to high level (speaker outputs of head unit). In both
cases RCA cables function as line-inputs.
8 Highpass on/off control CH1 + CH 2
If this switch is set on the crossover frequency for the highpass
can be adjusted with control 9.
9 Level controls for input sensitivity CH 1 + CH 2
These controls can be used to match the input sensitivity of the
individual channels to the output voltage of the connected head
unit. These controls are not volume controls and are solely inten-
ded for the purpose of sensitivity trimming. The control range
extends from 200 mV to 4 V.

11 Signal inputs CH 3 + CH 4
The ESPRIT amplifiers have RCA connectors for RCA cables that
.
can be connected with the pre-amplifier output of the line-outputs
of the headunit or with a pre-amplifier. This connectors are gold-
plated to ensure a better signal transmission.
12 High- and low level signal switch CH 3 + CH 4
To change the input signals from low level (head unit or pre-
amplifier) to high level (speaker outputs of head unit). In both
cases RCA cables function as line-inputs.
13 Highpass on/off control CH 3 + CH 4
If this switch is set on the crossover frequency for the highpass
can be adjusted with control 9.
14 Level controls for input sensitivity CH 3 + CH 4
These controls can be used to match the input sensitivity of the
individual channels to the output voltage of the connected head
unit. These controls are not volume controls and are solely inten-
ded for the purpose of sensitivity trimming. The control range
extends from 200 mV to 4 V.
10 Speaker terminals CH 3 + CH 4
To connect the speaker cables.
Never connect the loudspeaker cables with the car chas-
sis ground. It damages your amplifier. Ensure that the loud-
speaker systems are correctly connected (phase), i.e. plus to plus
and minus to minus. Exchanging plus and minus causes a total
loss of bass reproduction.The plus pole is indicated on most spea-
kers.
The impedance per channel should not be lower than
2 ohms as overheating could cause a shut down of the amplifier.
