Specifications

1. GENERAL PRODUCT
INFORMATION
Thank you for buying a DLS amplifier. The design is
a result of many years of experience and listening
tests.
Only the best components are used in this product.
To ensure maximum performance and reliability,
please follow the instructions and recommend-
ations in the installation section.
2. INSTALLATION PREPARATION
Sections 2 - 4 in this manual are common for both
amplifiers. In section 5 & 6 you will find connection
diagrams for each amplifier model.
2.1 LOCATION
Careful planning before attempting installation will
repay the small amount of extra time taken. Choose
a location for the amplifier which will allow plenty of
air to circulate around the fins on the top of the case.
Vertical mounting is to prefer. Do not mount the
amplifier upside down under the hat rack.
Mount the amplifier as far away as possible from the
aerial if AM reception is important.
In the amplifier case there are double mounting holes
to make the installation job easier. The screws
supplied in the mounting kit are self drilling when used
in a powerdriver. Should you wish to pre drill the
mounting holes, use a 3,5 mm drill. If the hole locations
do not line up with your mounting surface mount a
separate fibre board or similar where you attach the
amplifier. This will also isolate the amplifier chassie
from ground.
NOTE! Before you start drilling, make certain that
there are no fuel or brake lines or wiring looms
behind where you intend to drill.
2.2 POWER CABLES
The DC power wiring is extremely important. It is
essential that the amplifier at all occassions gets all
the power it needs without voltage drop, otherwise
both the dynamics and the good sound will be lost.
A poor battery can also cause a bad sound
reproduction, escpecially in the bass range. Some-
times it is necessary to mount an extra battery.
All cable connections requires a 2 mm hexagon key
to connect the terminals.
In most cases a so called ”Power Cap” can be useful.
It is an energy storage capacitor designed to supple-
ment audio amplifiers during high current demand.
The overall bass response of your audio system will
be enhanced with the use of this due to it´s ability to
store a large amount of current and discharge it in a
short period of time.
If you have more than one amplifier in the system
you must increase the cable size and fuse compared
to the table. When connecting two or more amplifiers
use some of the DLS Fuse blocks with built in fuses
to split the power to each amplifier. The short cable
from the Fuse block to the amplifier can have a smal-
ler size for easier installation.
Don´t connect to battery before you have double
checked all connections.

In the table below you will find suitable cable areas
and fuse sizes for different cable lenghts.
The gold plated terminals will directly recieve
power cables up to 16 mm

(5AWG).
Mount a fuse holder (DLS FH 1 or similar) on the DC
-cable near the positive battery terminal. Use the
same cable size from the negative amplifier terminal
and connect to the nearest earth point.
Make sure to have a good earth contact, if necessary
clean the metal from paint etc. A poor earth contact
can cause damage to other parts in the system, for
example the head unit if the earth current is forced to
pass through the shield of the signal cable.

then the cable gets too warm before the fuse blows.
