How to install and

operate the

DLS CAD11

digital mono

amplifier

Welcome!

This owners manual is written in easy english and

uses a lot of drawings to simply the installation and

use of the above amplifier.

Your DLS amplifier must be installed correctly in or-

der to work well. This manual will show you how to

install the amplifier like a pro. Please read the entire

manual before beginning the installation.

Install the amplifier yourself if you feel confident with

our instructions and if you have the proper tools.

However if you feel unsure, turn over the installation

job to someone better suited to it.

Use ring crimp terminal cable to connect to battery +. Apply silicon grease to the fuse to prevent corrosion. Use a fuse holder for ANL fuses +12V REM GND +12V REM GND like the DLS FH2B. Fuse value 100 A if you use a AWG4 cable. DLS DLS FH 2B fuse holder Connect the battery cable to the +12 Volt on the amplifier.

Input and controls 12 12 12 12 12 12 12 12 12 Input Level control Input Wiring Inputs may be low level from the RCA output of the car stereo or high level from the car stereo speaker output.Low level = RCA is to prefer for the best sound quality. Important Use either the low level or the high level input, do not use both at same time. 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).

CAD11 Bass boost control on CAD11 Bass boost control is used to set the bass volume. You can select the amplification between 0 dB and +18 dB at a 45 Hz center frequency. This function is used to compensate for the bass box function and to adjust for your own taste of bass. Set level control at 0 dB if you want it to be inoperative. Remote Bass level control Bass Boost 0 dB You can fine tune your bass level from the front of your car.

CAD11 Bridging two amplifiers Connecting two CAD11 in bridge mode will double the output power. Minimum speaker load is then 2 ohms. The output power with a 4 ohm load is 1500 Watts, and with 2 ohm load 2000 Watts. The RCA signal must be connected only to the amplifer set to run as ”Master”. The filters as well as the level control is only working on the ”Master” amplifier.

CAD11 Professional Tip: 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. 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.
