Safety instructions
Attention !
Please read all warnings found in this manual. This information is highlighted and is
included to inform you of the potential danger of personal injury or damage to property.
Hearing Damage
Continuous, excessive exposure to sound pressure levels in excess of 85 dB can cause
a loss of hearing. ETON components are capable of producing sound pressure levels greater
than 85 dB.
Volume and Driver Awareness
Use of sound components can impair your ability to hear necessary traffic sounds and
may constitute a hazard while driving your automobile.
ETON accepts no liability for hearing loss, bodily injury or property damage as a result
of use or misuse of this product.

Before Putting into Operation
Hint
The installation and adjustment of the amplifier should only be entrusted to qualified personnel.
Please carefully read the operation instructions and follow the given directions regarding connection and
adjustment of the amplifier.
Warning
Before connecting external devices that do not belong to this amplifier, please refer to the
corresponding directions contained in the operation instructions for this device.
Warning
Under no circumstances should you open the amplifier or attempt any repairs. If required contact
your dealer to obtain technical assistance. Unauthorized changes will result in the cancellation of
warranty.
Warning
The amplifiers are exclusively designed for the interior of vehicles with a power supply of 12 volt
DC (Direct Current). The surrounding temperature may vary from 0° to 60° Centigrade.
Attention
Install the amplifier only in the interior of the vehicle or in the trunk. Never install the amplifier in
the motor space under the hood.
Warning
The amplifier must not be subjected to pressure and not be covered.
Warning
Be careful that no foreign object or fluid can enter the amplifier. Be sure the amplifier is provided
with sufficient air circulation to achieve proper cooling of the cabinet.
Warning
The amplifier should be mounted in a vertical position within an area of the vehicle that allows
good air circulation.
Attention
The heat sinking device can reach a temperature over 80° Centigrade. Be careful to avoid contact
with temperature sensitive surfaces or materials.
Attention
Be sure that no components are close to the mounting position of the amplifier that could be
damaged by the screws or during the mounting procedure.
Damage to the vehicle can severely endanger the automobile safety as well as the safety of
the passengers.
Attention
Mount the amplifier using the four fastening clips. Be careful that you choose a strong, stable
surface that can carry the weight of the device. Avoid mounting on plastic parts or cardboard lining.

Cabling
Power Supply
Connections and Adjustments
Attention
Use only a cable of sufficient diameter for the power supply connection. Refer to the technical data
in appendix. A cable of greater diameter is always recommendable.
Hint
The diameter of the grounding cable must be at least as large as the diameter of the plus cable.
Warning
Lay the cables single and one after the other. Pay attention to professional mounting. Cables
leading through metal components should always be protected by rubber sleeves. Use only
appropriate cable shoes and isolation covers.
Warning
Avoid bending the cable in a 45° angle. Avoid contact with sharp metal parts or surfaces that could
damage the isolation.
Warning
Always disconnect the battery clamps before performing any maintenance, mounting or
demounting. In any case disconnect at least the minus pole.
Attention
Always install a fuse to the plus cable of the power supply coming from the battery as close as
possible to the battery clamp. If possible use the enclosed fuse.
Attention
When connecting an external capacitor always refer to the instructions enclosed with the capacitor.
We do not grant warranty for any damage caused by improper usage of external power supply
systems.
Attention
Be careful that the ground connection is reliable. Connect the cable only to a metal part of the
vehicle where all paint and other residue have been thoroughly removed.
Warning
Use cables of proper length. Keep the cables as short as possible.
Warning
To ensure that the interference suppression system can function, the cinch entry connections may
not make contact to the metal cabinet of the amplifier.
Warning
Perform any adjustment to the amplifier selection switches only with the amplifier shutoff.

Connection and Operating

Connection Description
Entry
The amplifier is equipped with three cinch stereo entries (6;7 and 10;11, 15,16). Connect the pre-amplifier
signal of your car radio or DVD player etc. to these connectors.
The sensitivity controllers (8,12 and 17) are used to adjust the entry signal to the amplifier.
Filter
The amplifier is equipped with HP and LP filters. With these filters it is possible to correspondingly adjust the
signal processing in the amplifier (23, 28, 36, 38). When the filters are shut off, the entry signal is linear
amplified (21,27,35,37)
Remote Control
Volume control with the remote control device can only be achieved through the subwoofer channels. The
remote control device is activated by placing switch (30) in the ON position.
Loudspeakers
The loudspeakers of the system are attached to the clamps plus and minus of the performance exits
(39,40,41).
This amplifier is equipped with exceedingly high filter capacity enabling it to be employed in a large number
of applications. We are only able to provide a few sample configurations:
6 Channel Operation
The loudspeakers are connected according to diagrams 39a, 39b and 40a, 40b and 41a, 41b.
5 Channel Operation
The front and rear loudspeakers are connected in stereo operation as shown in diagrams 39a, 39b as well
as 40a, 40b. The subwoofer connection is shown in diagram 41c.
Tri Mode
The front loudspeakers are connected in bridged stereo operation as shown in diagrams 39c and 40c. The
subwoofer is connected in bridged operation as shown in diagram 41c.
Full Active Operation
The filter equipment of the amplifier allows you to actively operate a 2 way front system (without additional
crossovers). Simultaneously a subwoofer can be actively employed.
Attention:
Take the polarity of the loudspeakers into consideration. Refer to the polarity specifications on the
terminal.
Power Supply
The plus cable coming from the battery should be attached to socket 4. The mass cable should be attached
to socket 5 and the control cable to socket 1.
Always use the enclosed fuse in the plus cable.
Security System
The operating state of the amplifier is controlled by protecting circuitry that in the event of disturbance
(short-out, equal voltage at the loudspeaker exit, pump effect and overheating) switches on to protect the
amplifier and the connected audio system. In this case the PRT LED (3) lights up.
Disturbance Suppression
The amplifier is equipped with circuitry that softens electric and electro-magnetic disturbances created by the
vehicle.
Ventilation
The amplifier is cooled by the cabinet. Ensure that the cabinet receives sufficient air circulation.

First operation
Before reconnecting the vehicle battery, ensure that all connections correspond to the instructions contained
in this operations manual. Verify that all installation steps are in accordance with the safety regulations.
Reduce the volume of your control device to a minimum and switch the device on.
If the connections are correct the amplifier will also switch on and the green LED operational display (2) will
turn on.
Sensitivity Adjustment
(not for full active operation)
Using a flat screw driver turn the potentiometers (8,12,17) to the left as far as possible. Reduce the volume
of your control device to a minimum and switch the device on. Adjust the volume of the control device to
about 75% of the final value. Now turn the controllers (8,12,17) clockwise until the first distortions in the
loudspeaker can be heard. Turn the controller slightly in the reverse direction until the distortions disappear.
Maintenance
In case of damage contact your dealer.
Cleaning
Clean the amplifier with a soft brush and a slightly dampened cloth. Never use any cleaning solution.
Be careful not to change the position of the selection switches and the adjustments on the control panel.
Replacement of the Fuse
Replace the fuse only when you are sure that the control device is turned off. Remove the defective fuse
and replace it by an identical fuse having the same electrical value.
