How to install and operate the DLS UL TIMA TE A-series amplifiers A1, A2, A3, A4, A5, A6, A7 & A8 Welcome! This owners manual is written in easy english and uses a lot of drawings to simply the installation and use of the above amplifiers. Y our DLS amplifier must be installed correctly in order to work well.
Installation Before you begin to install 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. Amplifier location Important Allow air circulation around the amplifier .
T ools and material needed T ools: Flat and Phillips screwdrivers Wire cutter Wire stripper Electric drill with drills .
Connect the fuse holder as close to the vehicle battery + as possible, using A WG 5 = 16 mm 2 or heavier cable (see table on page 2). Use ring crimp terminal cable to connect to battery +. Apply silicon grease to the fuse to prevent corrosion. Connect the battery cable to the +12 V olt terminal on the amplifier .
Low level input Use a pair of shielded stereo audio cables with RCA type jack. Most trunk-mount amplifiers need a 20 feet RCA cable ( appr 5 – 6 meters). Most under the seat installations require 12 feet ( 2 – 3 meters) RCA cables. Avoid placing the RCA cable close to spea- ker cables, power cables and remote control cable.

Crossovers / filters (general) DLS A-series amplifiers include highpass filter ( HP ) and lowpass filters ( LP ). The HP-filters can be used in one of two ways. Either as a subsonic filter together with a subwoofer to remove the lowest frequencies which often causes a rumbling bass reproduction.
The LP-filter on the rear channels is used when you run a 2-way or 3-way speaker system with active crossover . It will allow low frequencies only and blocks higher frequencies. The filter can be switched in and out. The normal frequency range is from 0,3 to 4 kHz.
NOISE PROBLEMS WHINING NOISE V AR YING WITH ENGINE REVOLUTIONS: 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.
On the following pages you find some examples of how to connect the amplifier for different use. The drawings show normal level and filter settings. The main dif ference between DLS A1 and A2 is the lowpass filter and the power output. A1 has a 3-way filter selector under the bottom plate and A2 has a continously variable filter on the front.

Remote Pre out Subwoofer 4 ohm Y ou can use all DLS 4 ohm subwoofers in this example. For power cable, speaker cable and fuse size selection we refer to page 4.
WIRING EXAMPLES DLS A3 On the following pages you find some examples of how to connect the amplifier for different use. The drawings show normal level and filter settings. The two channels are divided into two separate mono amplifiers. There are separate DC inputs for each channel but they are internally connected with each other .
2. One or more subwoofers in mono bridge mode Y ou can use all DLS subwoofers in this example. Speaker impedance must be 4 ohm. For power cable, speaker cable and fuse size selection see page 4.

2. A front system connected in stereo bridge mode on all four channels. Y ou 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 see page 4.
3. Connecting a 3-way system using active crossover between woofer and midrange. Y ou can use all 3-way speaker systems in this example. Y ou can also use any 2-way system in combination with a separate mid bass speaker . Speaker impedance must be 4 ohm.
Y ou can use all DLS coaxial, 2-way , 3-way systems and subwoofers in this example. All speakers must be 2-4 ohm. If the head unit has only one pre out, a Y -cable must be used.
DLS A6 is 1 ohm stable. This means that you can connect four 4 ohm subwoofers in parallel without damaging the amplifier . If you have a 4 ohm sub with dual voice coils you can connect the coils in parallel, one coil to each amplifier output. NOTE! The speaker output terminals are internally connected in parallel.

25 T esting Before you finish the installation, you should do the following tests to make sure the wiring is correct and everything is operating properly . Reconnect Battery When wiring is complete, reconnect the battery negative terminal. If problems occour during the installation, or later , this guide might help you to find out whats´s wrong.
