SAFETY INSTRUCTIONS A The product's warranty is rendered void in cases of damage resulting from failure to comply with safety and operating instructions. We do not accept any liability for consequential damages. We do not accept any liability for personal iniury or damage to property caused by incorrect handling of the device or failure to observe the safety and operating instructions. In such cases the warranty is rendered void.
SETUP AND INSTALLATION A To ensure proper operation, please read these instructions carefully before installing and using this amplifier. Modifications to the vehicle requried by installation of the amplifier or other components should always be done in a way that does not affect the road safety or the designed stability of the car. If you are in doubt when selecting a place for installation, consult your local car dealership.
, -I • Mark the holes for the screws at the place of installation. The simplest way to do this is place the amp where you want it and use it as a pattern. • Drill the holes for the fastening screws . • Secure the amplifier with sheet metal screws. A To avoid short circuits and resulting damages to the device the negative terminal (ground) of the car battery must be disconnected first. Before reconnecting the negative terminal to the battery, make sure that the amplifier has been completely connected.
POWER CONNECTIONS Connect the "B+" connector of the power supply's terminal directly to the car battery's positive terminal Connect the "REMOTE" or "REM" connector to the terminal on the power supply, to the remote control connector, or to the antenna control output of the car's radio. The amplifier will be switched on via this input when +12V current is applied. Almost all car radios have an output which provides a +12V current when the radio is turned on.
4-CHANNEl MODELS Connect the RCA outputs of your car radio to the RCA connections IN (1) of the amplifier. rear car stereo outputs > connect to amplifier REAR IN front car stereo outputs > connect to amplifier FRONT IN Pay attention to the marking on the RCA connections: L > left R > right If your car radio does not have 4 preamplifier outputs use an optional Y-adapter. You will not be able to fade signal front to back when connected in this way.
Keep the length of the connection cables as short as possible. Do not install the RCA cables close to other cables to avoid interface at the amplifier input. Only sources with a RCA plug should be connected to the RCA inputs and A only speaker outputs should be connected to the speaker inputs to avoid distortion or mismatches that could damage the power amplifier. Please note the connection loads ln the Technical Data.

CONNECTING THE RCA OUTPUTS In addition to the speaker outputs, all models except the M4100 have RCA outputs so the input signal can be fed to other components of the car's audio system. A To use the preamp output, connect the connection OUT (8) with the input of the subsequent component, connecting the L channel to the left input of the device, and the R channel to the R input of the device. When connecting the RCA outputs, use only shielded RCA cables suitable for this purpose.
FUll: Crossover switched off, the amplifier branch plays back the complete frequency range HPF: High-pass crossover switched on, the amplifier branch only plays back the frequency range above the frequency set via the HPF (6) control unit. lPF: Low-pass crossover switched on, the amplifier branch only plays back the frequency range below the frequency set via the LPF control unit (8). low frequencies below the level the switch is set to.
immediately. Check all connections and loudspeakers. If you cannot detect an error, please call us at 1-800-955-9094 for help. Take care that the maximum volume is within the power capacities of the speakers and amplifier. Exces sive volume can damage the speakers and amplifier. If you use a subwoofer, changing polarity may improve the sound quality. Often reversing the terminal connections result in better bass (depending on the location of the subwoofer) .
A Circuitry that carries electric current may be exposed if the amp's cover is opened or components are removed. The amplifier must be disconnected from all voltage sources before carrying out servicing or repair works. Remember that capacitors in the amplifier may retain an electric charge even after disconnecting them from all power sources. Repair work should always be carried out by us. If you have to replace fuses, make sure you only use fuses of the same type and rated current (see "Technical Data").
The indicator LED POWER (11) lights, but there's no sound: • The volume control unit of the car radio is set to minimum. • The GAIN control unit (3) of the amplifier is set to minimum. • The speakers are not properly connected. The indicator LED PROTECTION (12) lights, and there's no sound: • The short-circuit protection of the amplifier has been triggered due to a short circuit at the speaker output. • The temperature protection of the amplifier has been triggered due to overheating.
• Bad ground contact of the ground connection cable, the ground point of the cable or of the battery terminal is corroded. The device turns on and off during operation: • Voltage too low at the B+ connection of the power supply's connection terminal, theground point of the cable or of the corroded battery terminal, battery too weak. • Intermittent contact at the REMOTE cable, REMOTE or REM connection of the power supply's connection terminal shows is loose or corroded.
