CAUTION!

Some of our amplifiers are capable of producing a sound pressure level that can cause permanent damage to your hearing system. High sound pressure levels combined with long time listening can give permanent damage to your hearing system. Choose a listening level that is comfortable for your ear. To establish a safe level: Start your volume control at a low setting. Slowly increase the volume until you can hear the music comfortly and clearly, without any distortion. Sudden sound shocks are dangerous.

The following noises can be dangerous with constant exposure:

GENERAL, POWER CABLING

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 recommendations 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 f or 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 aw a y 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 dr ill. 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! Bef ore 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. Sometimes it is necessary to mount an extra battery. All cable connections requires a 2 mm hexagon key to connect the terminals.

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 mm2 (5AWG). Mount a fuse holder (DLS FH 1 or similar) on the DC

-cable near the positive battery terminal. Use the same cable siz e from the negative amplifier terminal and connect to the nearest earth point. Make sure to ha ve 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 f orced to pass through the shield of the signal cable .

Recommended cable size for the DC-feed. Cab le length: < 1,5 m 1,5 - 5 m > 5 m

Amplifier:

DS 100 10 mm216 mm DQ 200 16 mm221 mm

Recommended main fuse for the amplifier s: Amplifier Fuse value Fuse holder

DS 100 AGU 40 A FH1/FH1B DQ 200 AGU 60 A FH1/FH1B

A cable of a certain size can´t have to large fuse, then the cable gets too warm before the fuse blow s.

Max fuse values for different cable sizes:

6 mm2 (9 AWG) 25 A 10 mm2 (7AWG) 40 A 16 mm2 (5AWG) 60 A 21 mm2 (4AWG) 100 A 33 mm2 (2AWG) 140 A 42 mm2 (1AWG) 200 A

If you have more than one amplifier in the system you must increase the cab le size and fuse compared to the table . When connecting tw o 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 bloc k to the amplifier can have a smaller size f or easier installation. Don´t connect to battery before you have double checked all connections.

In most cases a so called ”P ower Cap” can be useful. It is an energy storage capacitor designed to supplement 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.

CABLING, SIGNAL CABLES, SPEAKER CONNECTION

2.3 SIGNAL CABLES

DS 100 has one gold plated phono socket pair

provided to recieve the signal from the head unit. DQ 200 has two phono socket pairs. One for each amplifier part. When the amplifier is being operated in bridge mode both inputs must recieve an input for full power output.

Use high quality interconnects like the DLS SL5 PR O or similar with an effective shielding that prevents interference from the engine or alternator. When using this cable you m ust run a separate wire f or the remote.

When you run the signal cables remember to keep them well spaced from the wiring loom and the power feed to the amplifier to a v oid picking up interf erence. Lay the power cables and signal cables separated on each side of the car. Any extra cable must be laid in zig-zag style and definitely not coiled. Or cut it to correct lenght.

REMOTE WIRE

Some signal cables include a thin wire for remote amplifier start. High quality cables normally requires a separate wire for this. Connect between the head units remote cable (often the same cable that´s used for automatic power antennas) and the REM-terminal on the amplifier.

NOTE! If you want to star t more than one amplifier using the remote output, the current load might be too high for som head units. High currents may damage the head unit, check in the manual for the head unit. Sometimes you must add a relay to the remote circuit that takes care of the higher current. If you are uncertain of how to connect the relay, ask your local DLS dealer for advice.

2.4 SPEAKER CONNECTION

The gold plated terminals will directly recieve speaker cables up to 6 mm2 (9AWG). Always use high quality speaker cables such as DLS SC 2x1,5, SC 2x2,5 or SC 2x4. Subwoofer connection requires 2 x 4 mm2 cable. Connect the speaker + (marked with + or a red dot) to the amplifier + terminal, and the speaker

- to the amplifier -. When fitting the cables to the terminals, remo ve only 10 mm of the insulation. Twist the wire strand together and insert the wire after loosening the terminal screw . Do not over tighten as this can cut the cable strands. Use a 2 mm hexagon key to the ter minals.

PROTECT YOUR CABLES!

To prev ent the cable insulation from beeing damaged over sharp metal edges we recommend the use of cable protection tubes or similar. A damaged cable insulation could cause serious damage to the amplifier not covered by any guarantee.

SPEAKER POLARITY CHECK.

All speakers in a car audio system should be connected in phase (the same polarity). All speaker cones must mov e in the same direction. Out of phase speakers will cause a lack of bass, and a poor stereo soundstage.

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 remov ed. 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 crossov er, try to connect this with v arious polarity and judge what sounds best. The phase shift in passive crossovers sometimes makes it necessary to change polarity.

Battery 1,5 Volt

NOTE! Tweeters can not be tested this way, doubl e

check the connections instead.

SPEAKER LOADS

Most car audio speakers have a 4 ohm impedance. DLS amplifiers can be loaded down to 2 ohm on each stereo channel. In mono bridge mode operation the speaker load must never be less than 4 ohm. If you are using more than one driver they must be connected in a way so the impedance still is 4 ohm when connected to the amplifier . When you run the amplifier in mono bridge mode it sees a 4 ohm load as 2 ohm. On page 4 you find different speaker wiring e xamples.

Don´t forget that the output power from a multimode connected amplifier is more than double the normal power. The speakers m ust be able to handle this power.

If you want an extra high class speaker cable choose any of the DLS SCP, SCK, SC 4x1 or SC 4x1,5 cables.

MULTIMODE OPERATION

Multimode operation means that you connect one or two systems in normal stereo mode and then add one or more subwoof ers in mono bridge mode to the same speaker terminals. A center channel can be connected in the same way. To avoid amplifier overload you must ALWAYS use passive filters in multimode operation. The subw oofer needs a 12 dB lowpass crossover and the stereo system needs a 6 or 12 dB highpass crossover.

CAUTION! In mono bridge mode the speaker impedance must never be less than 4 ohms. The amplifiers sees a 4 ohm speaker as a 2 ohm load.

2.5 BRIDGE MODE OPERATION

Subwoofers are normally connected in mono bridge mode to the amplifier. This is done by connecting the speaker + to the amplifiers LEFT+ terminal, and the speaker - to the amplifiers RIGHT- terminal. Now the speaker will recie ve a signal that is the sum of the signals from each channel.

2.6 PASSIVE CROSSOVERS

12 dB highpass crossover:

For maximum use of the DLS amplifiers it´s useful to know a little about passive crosso ver design. Passive crossovers are often used for conncting subwoofers

in multimode operation or f or center channel speak ers. To remov e frequencies ov er a certain frequency (the crossover frequency) use a filter with a 6 or 12 dB slope. This type of crossover is often used in combination with a subwoofer.

95 Hz 10 mH 300 µF 140 Hz 6,3 mH 200 µF 190 Hz 4,7 mH 150 µF All valid for 4 ohm speakers.

6 dB lowpass crossover:

Consists of a coil connected in series with the driver.

NOTE! All DLS amplifier s are equipped with internal low- and highpass crossovers. External passive cr ossov ers are used only in multimode operation.

This table shows the crossover frequency of a 6 dB lowpass filter at different impedances and frequencies .

12 dB lowpass crossover:

Consists of a coil in series and a bipolar capacitor connected in parallel with the driver.

If you w ant to limit the lower frequency response, for example to a stereo system in multimode operation, a 6 dB slope crossover is perfect. Just connect a bipolar capacitor in series with the driver.

6 dB highpass filter:

2.7 LEVEL SETTING

To adapt the amplifier to all kind of signal sources with varying levels there are gain controls provided on the amplifier next to the phono sockets. They should not be used as volume controls. Start with a ”12 o clock” setting of the le vel controls. I f you set the head unit volume to 75% of maximum you should achieve a good sound without distortion. Find a point of the lev el setting where the distortion is just discernible. At this point slightly reduce the control to eliminate the distorsion. On a multi channel amplifier like the DQ 200 it´s necessary to adjust the levels indiviually to achie v e a good sound balance between the different speak ers, different speakers have different sensitivity. When using two of the channels for subwoofer operation, start the level adjustment on these channels. After having adjusted the bass le v el for good performance, adjust the level to the front system for a good sound balance. In multimode operation you can´t adjust the subwoofer level separately.

2.8 FINAL SYSTEM SETUP

Before connecting the amplifier to the batte y , rechec k all connections. When you connect the main fuse you will see a little spark, this is normal. But if the fuse blows at this moment, something is wrong. Recheck the cabling. Turn on your head unit, the amplifier starts and the red LED is lit. Increase the volume and make sure all speaker works. Readjust levels and crossover settings if necessary. The level settings might need to be readjusted after 25 - 30 hours of use.

2.9 PROTECTION CIRCUITS

This table shows the crossover frequency of a 6 dB highpass filter at different impedances and frequencies .

The amplifiers hav e an internal high current protection circuit shutting down the amplifier if the current draw is too high. It is indicated with a yello w LED . The protection circuits will reset by turning the head unit off and on again. There are two 25 Amp fuses on the front. Disconnect the main fuse bef ore replacing any of these. Always replace with the same type and v alue. The amplifiers also have a thermal protection that turns off the amplifier at 95 C. It will resume operation after cooling down. If necessary install an external cooling fan.

INTERNAL FILTERS, FAULT FINDING GUIDE

3. INTERNAL FILTERS

3.1 DS 100

DS 100 has an internal variable lowpass filter that can be switched in/out. It can be set from 50 up to 200 Hz. It also has an internal higpass filter that can be set from 15 up to 200 Hz.

LOWPASS FILTER:

The lowpass filter is normally used together with a subwoofer to remove higher frequencies over the crossover setting. A normal filter setting is 80 - 100 Hz.

HIGHPASS FILTER:

The highpass filter can be used in one of two ways. Either as a subsonic filter together with a subwoofer to remove the lo west frequencies which often causes a rumbling bass reproduction. A normal setting is 20

- 30 Hz. The highpass filter can also be used together with a front or rear stereo system to remove frequencies below the crossover setting. In a system with a separate subwoofer it´s common to limit the bass reproduction to the front system. A normal setting is between 80 - 120 Hz, b ut feel free to try other settings.

THE AMPLIFIER TURNS OFF AFTER 10 - 30 MINUTES.

The amplifier is ov erheating due to inadequate v entilation. Check mounting position is free from obstruction.

Do this:

1. Move the amplifier to a place with better ventil-

ation.

2. Install one or two fans to cool down the heatsink.

3.Ov erheating can also be caused by an impedance

load below the le vel permitted. Refer to the section about speaker loads.

NO OUTPUT FROM ONE OR MORE SPEAKERS: Check the following:

1. Balance control position.

2. Fader control position.

3. Speaker cable connections to both amplifier and

drivers.

4. Signal lead plugs and cables.

5. Change left and right signal lead plugs in the

amplifier to see if the problem mov es to a diff erent speaker, the the lead has a fault. If the problem remains, the speaker or amplifier are at fault.

3.2 DQ 200

DQ 200 has the same filter configuration as the DS 100, but it´s doub led as this is a four channel amplifier . Suitable filter settings at diff erent connections is found in the section with connection examples.

4. FAULT FINDING GUIDE

If problems occour during the installation, or later, this guide might help you to find out whats´s wrong.

THE AMPLIFIER IS DED:

1. Chec k power lead, g round 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 pow er lead for short circuits.

4. Check the amplifier protection fuses. Are these broken change to new ones with the sama value. If short circuiting continues, contact y our 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.

AMPLIFIER PRO TECTION FUSE BLOWS AT LO W VOLUME :

1. One or more speaker cab les are shorted. Make an

insulation test with a multi meter. The cables must not have a connection to earth.

4.1 NOISE PROBLEMS

WHINING NOISE VAR YING WITH ENGINE REV OLUTIONS:

Do this:

1. Rewire the power supply (12 V) to source unit

direct from battery.

2. Rewire ground wire from source unit to clean position on chassis.

3. Check all power connections to ensure that they are clean and tight.

4. Check quality of system ground connection.

CONSTANT WHINING NOISE:

Do this:

1. Ensure that all equipment is grounded at the same

place.

2. Check quality of earth strap connection from battery negative terminal to chassis.

3. 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, re-route 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-cab les are Quasi-balanced.

CONNECTION DIAGRAMS DS 100

5. CONNECTION DIAGRAMS DS 100

On the following pages you find some examples of how to connect the amplifier for different use. Th e pictures show normal level and filter settings.

DS 100 can be connected in many different ways:

1. As a stereo amplifier connected with a speaker system of coaxial, 2-wa y or 3-way type.

Two speaker systems can be connected in parallel, one front and one rear system.

2. As a subwoofer amplifier with max two 4 ohms subwoof ers per channel in stereo, or max one 4 ohm subwoofer in mono bridge mode. The built-in lowpass crossover is used.

3. In multimode with one system in stereo and one 4 ohm subwoofer connected in mono bridge mode using a passive crossover filter for both the front system and the subwoofer. Connect as in the example

5.4 or use DLS premade multimode filter.

4. Using two DS 100 you can run the front system on one of them (example 5.1) and the subwoofer on the other (example 5.3). The highpass filter to the front system amplifier should be set at 80 - 100 Hz, or maybee higher. Make your own tests for best result.

5.1 One speaker pair connected in stereo.

You can use all DLS coaxial, 2-way or 3-way systems in this example. The speaker impedance must be 4 ohm.

MULTIMODE OPERATION:

In multimode operation y ou can connect a speaker system in normal stereo mode and a subwoofer in mono bridge mode on the same output terminals. To split the signals between the speakers passive crossovers must be used. Connect a 200 µF capacitor in series with the plus leads to the stereo system (works as a 6 dB highpass crossover). To a two- or three way system it´s enough to connect the capacitor in series with the woofer driver. Connect a 12 dB lowpass crossover to the subwoofer consisting of a 10 mH coil in series and a 300 µF capacitor in parallel with the subwoofer. The components used are shown in the drawing. The coil must have a low inner resistance to avoid losses. Use the DLS 10 mH, 0,47 ohm coil with art. no 10-

42310.

WARNING! Never run a multimode connected system with the subw oofer disconnected and still having the

µµ

300

µF capacitor connected. The output circuits in the amplifier can be damaged. Solder the

µµ

capacitor directly on the subwoofer terminals so it will be disconnected at the same time as when you disconnect the subwoofer.

The four channels are divided in tw o amplifier b loc ks with the signal input to the right, then the le vel control, the filter and to the left the speaker terminals.

DQ 200 can be connected in many different ways:

1. As a stereo amplifier with one front and one rear system.

These can be of coaxial, 2-way or 3-way type. Two speaker systems can also be connected in parallel. For e xample one pair in the back doors and one pair in the hat rack connected to the rear output on the amplifier.

2. One front (and if you want also a rear system) in the doors or dashboard, and one subwoofer in mono bridge mode to the amplifier rear output.

3. In multimode with a front stereo system connected to front output, and a rear stereo system to rear output together with a subwoofer in mono bridge mode using passive crossov ers.

4. A stereo system connected in mono bridge mode on both front and rear output. This gives a higher output to the speakers.

5. A 3-way system can be connected with active crossover between woofers and mid/tweeters.

6.1 In stereo with one front and one rear speaker system.

You can use all DLS coaxial, 2-way or 3-way speaker systems in this example. Speaker impedance must be 4 ohm. If the head unit has only one pre out a Y-cable must be used. For power cable, speaker cable and fuse size selection we refer to section 2.2 - 2.4

MULTIMODE OPERATION:

In multimode operation you can connect a speaker system in normal stereo mode and a subwoofer in mono bridge mode on the same output terminals. To split the signals between the speakers passive crossovers must be used. Connect a 200 µF capacitor in series with the plus leads to the stereo system (works as a 6 dB highpass crossover). To a two- or three way system it´s enough to connect the capacitor in series with the woofer driver. Connect a 12 dB lowpass crossover to the subwoofer consisting of a 10 mH coil in series and a 300 µF capacitor in parallel with the subwoofer. The components used are shown in the drawing. The coil must have a low inner resistance to avoid losses. Use the DLS 10 mH, 0,47 ohm coil with art. no 10-42310.

6.5 Connection of a 3-way system using active crossover between woofer and midrange.

You can use all DLS 3-way systems in this example. For example DLS R 36, R 38, U35 & U36. Speaker impedance must be 4 ohm. If the head unit has only one pre out a Y-cable must be used. For power cable, speaker cable and fuse size selection we refer to section 2.2 - 2.4
