EQUIPMENT FEATURES AND CONTROL ELEMENTS ESPRIT E10
6
1 Connecting the ground cable
The ground cable should be connected to a central ground refe-
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 E10 is 4 x 20 amperes.
5 Power LED
Shows the operation mode of the amplifier.
6 Signal inputs
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 Bass remote connector
To control the bass level from the driver position.
8 Bass remote control
To set Bass remote on/off.
9 Level controls for input sensitivity
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 300 mV to 6 V.
10 Bass equalizer
To raise the bass signal from 0 to 18 dB at 45 Hz.
11 Phase control
This control enables the phase of the bass signal to be shifted by
180° in order to achieve optimum delay equalization with the
other channels.
12 Lowpass control
To adjust the crossover frequency from 40 Hz to 150 Hz.
13 Speaker terminals
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
