Installation
Before you begin installation
This amplifier is using the very best components in
all sections of the amplifier, from the input circuitry,
through the whole amplifier to the final stage output.
- Two pieces of CV4010 pentodes is used in the signal path. These tubes are made by VALVE Electronics
in England during 1982 - 1984. The Valve Electronics
company produced best sounding tubes in the tube
industry before they closed. The tubes are spare parts
for military equipment so they fulfil military
specifications.
- We use silver wire Capacitors in signal path and
power supply for a focused sound image.
- Special designed DLS Audio capacitors in key points
and WIMA polypropylene capacitors.
- Four pieces of 4700 uF on each channel for deep
and wide sound stage.
- Dual mono power system design plus separate
power supply for tube and pre-amp stage for clear
sound reproduction.
Before you begin you need to read the manual, to have
some tools, cables and other material available. There
is one such list of material on the following page.

The DLS ULTIMATE TA2 amplifier have a great
flexibility in mounting but the best is to mount it
somewhere in the trunk.
When you select a location, do remember that the
amplifier generates a lot of heat.
Choose a location where air can circulate freely
around the amplifier. Do not cover the amplifier with
carpets or hide behind trim panels.
Do not mount the amplifier in an inverted or upside
down position.
Check all locations and placements carefully before
making any cuts, drilling any holes or making any
connections.

the car stereo is turned on.
We recommend to use a separate remote wire and
run the RCA lead separate from remote wire, power
cables and speaker cables.
You can insert the cable directly into the amplifier
terminal. If there is no remote voltage available from
the stereo, you must connect to the ignition key
through the radio or any accessories fuse.

Low level input
Use a pair of shielded stereo audio cables with RCA
type jack. Most trunk-mount amplifiers need a 20

The HP-filter can be used as a
high pass crossover blocking
very low frequencies from
reaching the speakers. It is
mostly used at say 60 - 80 Hz
to protect small speakers ( like
6 inch and smaller ) from deep
bass. On this amplifier you can
choose a setting between 20 200 Hz. The slope of the High
pass filter is 12 dB / octave.
The filter can be switched off if
you want to run the amplifier in
full range mode.

Input Level controls
The input level controls (one for left, and
one for right channel), 7V – 0,5 V, matches
the output of your radio to the input of the
amplifier. After installation is complete,
make sure the input of the amplifier is turned down all the way ( counter-clockwise
at 7V ). Play a tape or CD, make sure all
bass or treble settings or equalizer are flat,
and turn the volume of the radio up until
you just start to hear distortion. Turn the
volume control down just a bit. On the
amplifier increase the input level control (
clockwise or to the right ) until you just
start to hear distortion, then back the level
control just a bit. Now your radio and
amplifier levels are matched. Both level
controls must be set to the same level.

All tubes need time to pre heat the heater. On TA2
the time for the valve to warm up is 45 seconds
indicated by blue LED light in the tube window on
top. After 45 sec. the LED colour changes to red.
Now the amplifier is reday for use. To get the perfect
sound quality it needs 30 minutes running.
LED indicator in tube window:
BLUE: Amplifier is warming up for 45 seconds
RED: Amplifier is warm and working
GREEN: Amplifier protection circuit in function
because of thermal overload, short circuit or DC-offset. Turn off the amplifier to reset. If the problem still
exists, check your wiring. If nothing helps, contact
your local DLS dealer for advice.
Running in time
As all tube amplifiers TA2 need one month or more
running in time for all components to work correct
and producing the outstanding sound quality that TA2
is capable of. The sound quality is very good from
the start but it will be even better after 30 days of
playing.
The amplifier is NOT
BRIDGEABLE.
Do not try to connect
speakers in bridge
mode.

Testing
Troubleshooting
Before you finish the installation, you should do the
following tests to make sure the wiring is correct and
everything is operating properly.
If problems occour during the installation, or later, this
guide might help you to find out whats´s wrong.
THE AMPLIFIER DOESN’T START:
1. Check power lead, ground and remote
connections at the amplifier using a multi meter.
2. Check the battery terminal connections.
3. Check the power lead fuse or circuit breaker. If
fuse damage continues, inspect the power lead
for short circuits.
4. Check the amplifier protection fuses. Are these
broken change to new ones with the same value.
If short circuiting continues, contact your local
DLS dealer. A fault may exist in the amplifier.
5. To start the amplifier requires a remote voltage of
9-15 volt. Check the voltage with a multi meter.
Reconnect Battery
When wiring is complete,
reconnect the battery
negative terminal.
Test power wiring
1.
2.
Turn on the head unit but do not turn up the
volume. The amplifier power light should
come on. If not, check the remote and +12
volt wires. Also check the ground
connection.
Turn up the head units volume slightly. All
speakers should operate. if not, check wiring
connections at amplifier and speakers.
Test speaker connections

AMPLIFIER PROTECTION FUSE BLOWS AT LOW
VOLUME :
1. One or more speaker cables are shorted. Make an
insulation test with a multi meter. The cables must not
have a connection to earth.
THE AMPLIFIER TURNS OFF AFTER 10 - 30 MINUTES.
The amplifier is overheating due to inadequate ventilation. Check mounting position is free from obstruction.
Do this:
1.
Move the amplifier to a place with better ventilation.
2.
Install one or two fans to cool down the heatsink.
3.
Overheating can also be caused by an
impedance load below the level permitted.
NO OUTPUT FROM ONE OR MORE SPEAKERS:
Check the following:
1.
Balance control position.
2.
Fader control position.
3.
Gain controls, left & right.
4.
Speaker cable connections to both amplifier and
drivers.
5.
Signal lead plugs and cables.
6.
Change left and right signal lead plugs in the
amplifier to see if the problem moves to a different speaker, the lead has a fault.
If the problem remains, the speaker or amplifier
are at fault.
7.
Make sure that DC cables are connected to both
the inputs.

Professional Tip:
NOISE PROBLEMS
SPEAKER POLARITY CHECK.
WHINING NOISE VARYING WITH ENGINE
REVOLUTIONS:
All speakers in a car audio system should be
connected in phase (the same polarity). All speaker cones must move in the same direction. Out of
phase speakers will cause a lack of bass, and a
poor stereo soundstage.
Do this:
1.
Check gain controls, They should NOT be
set to MAX sensitivity.
2.
Rewire the power supply (12 V) to source
unit direct from battery.
3.
Rewire ground wire from source unit to
clean position on chassis.
4.
Check all power connections to ensure that
they are clean and tight.
5.
Check quality of system ground connection.
6.
Install a Power Cap capacitor. This can be
helpful against most noise problems.
CONSTANT WHINING NOISE:
Do this:
1.
Check gain controls, They should NOT be
set to MAX sensitivity.
2.
Ensure that all equipment has a common
ground point.
3.
Check quality of earth strap connection from
battery negative terminal to chassis.
4.
Disconnect signal cables from amplifier to
see if noise disappears. If so the leads are
picking up noise. Test this by laying a new
cable over the seats and reconnecting to the
amplifier. If the noise does not return, reroute original cable away from source of
interference.
If noise remains regardless of cable position,
try to use so called Quasi-balanced signal
cables. DLS PRO-cables are
Quasibalanced.
Checking polarity:
Hold the - connection of the speaker wire to the terminal of a 1,5 Volt flashlight battery. Tap the +
wire on to the + terminal of the battery, and observe
the movement of the cone. The cone should move
outwards when the wire touches the battery, and
inwards when the battery is removed. If it is the
other way around, the speaker has been connected
backwards and it must be removed and connected
correctly.
If your system also has a subwoofer connected
through a passive 6 or 12 dB crossover, try to
connect this with various polarity and judge what
sounds best. The phase shift in passive crossovers
sometimes makes it necessary to change polarity.

NOTE! Tweeters can not be tested this way,
double check the connections instead.
Professional Tip:
Installing in trunk
When installing the amplifier in the trunk, run the
power wires along the same path as the other
vehicle wiring. Many cars have insulated channels
for wiring. you will have to remove the door sill trim
and the carpet.
Securing wires
Use wire ties to bundle together when possible.
(But never bundle speaker wires or signal cables
together with power wires.
Professional Tip:
Crimp connections
Purchase crimp connectors and crimping tool.
Connectors are color coded.
1. Strip 1/4 inch (6 mm) of insulation from the wire.
2. Insert into connector
3. Crimp tightly
Professional Tip:
Speaker and power wires
Do not run speaker and power wires next to each
other. Power wires can generate a ”siren” sound in
the speakers. Runs speaker and power wires on
opposite sides of the car.
