Using a felt tip pen or pencil mark the four holes to be drilled for mounting. NEVER use the amplifier as a template for drilling. It is very easy to damage the amplifier surface in manner. • Remove amplifier with a getting back the plastic panels. Drill four 3.5 mm. Diameter holes into mounting surface on steel panel. If you want mounting the MDF or wood panel, drill four 3.0m/m diameter holes into mounting surface. • If possible, test the system operating before final mounting of the amplifier. • Mount the amplifier using the supplied 4 self-threading screws. INSTALLATION DIAGRAM ? SOUNDMAX 5 SM-SA6042 Connections POWER SUPPLY AND REMOTE TURN-ON OF THE AMPLIFIER NOTE: Do not connect the plus terminals to the car battery before other connections, or it may occur short circuit. The gauges of power cables should be enough for the power amplifier demands at least 5.27mm2. The + 12V DC and ground cables should be at least 6 mm2. Firstly connect the GROUND terminal to the battery negative pole. It is very important that the connection is fastened. Loose connection may cause malfunctions or interference noise or distortion. Dirt residues must be carefully removed from the battery connection point. Then connect the +12V DC power terminal via an integrated fuse to the battery plus pole. The fuse must be located close to the battery, the length of cable from the battery positive pole to the fuse must be 50cm for safety. Install the fuse after other connections including the connection of the stereo and the loudspeakers. Finally connect the terminal of the remote turn-on to the amplifier REM control jack. The cable gauge of 0.75mm2 is sufficient for the amplifier REMOTE connection. AUDIO CABLES When installing the stereo input connection and the speaker connection, make sure the audio and the power supply cables do not run the same side of the vehicle. This reduces crosstalk interference to the audio cables. LOUDSPEAKER CONNECTIONS • In normal operation mode (I. e. one loudspeaker on each Individual amplifier channel), the lowest terminal Resistance is 2 Ohms per channel. • In bridge mode (two amplifier outputs combined), the lowest terminal resistance is 4 Ohms. • In tri-mode the lowest terminal resistance is 2 Ohms. • Never connect the loudspeaker negative terminals to the vehicle chassis. • Do not connect the +12V power supply to a loudspeaker output otherwise this will destroy the amplifier terminals. NOTE: If the amplifier is operated with lower terminal resistance or incorrectly application as described above, both the amplifier and the loudspeakers may be damaged. The warranty becomes void in such cases. SOUNDMAX 6 SM-SA6042 Operation elements SETTING THE INPUT AND SENSITIVITY The regulator for input sensitivity is used to adapt amplifier for each car radio or tape deck. Turn the volume control of your radio to central position and adjust the input-level control (2) Fig. 6, to produce medium volume. This setting can provide sufficient power and optimum Signal to Noise (S/N) ratio. CAUTION: Do not run the amplifier in high volume for long time, otherwise the loudspeakers will be damaged. LOW-PASS FILTER WITH ADJUSTABLE CROSSOVER FREQUENCY If the unit is used as a subwoofer amplifier, turn the switch (5) to" LPF". And set proper cross-over frequency with adjusting the control (3) to make the filter match the timbre requirement of the installed woofer. The crossover slope of the filter can accurately reduce the medium and high frequency ranges. HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY If the amplifier is used for satellite loudspeakers (mid-range/tweeter loudspeakers), turn switch (4) to "HPF". Set proper crossover frequency with adjusting the control (3). The frequencies only above the setting will be amplified. This can effectively minimizes distortions caused by excessive membrane movement at the low frequencies. And the result does not reduce the bass level when it is used for small power-supply loudspeakers. BASS-BOOST Use the bass-boost switch (6) to eliminate harmonic distortion of the lower bass frequencies and weaken the bass faction. OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS The input signal of the LOW INPUT connections L and R is directly output to the LINE OUT L and R jacks (1). Additional amplifiers can be connected to the LINE OUT jacks without additional T-plugs and cables. SOUNDMAX 7 SM-SA6042 Power supply/remote turn-on connection (1) Terminal for +12V battery voltage (2) REM terminal for remote turn-on (3) GND terminal for the ground, to the battery negative pole (4) Battery (5) Automatic antenna connection If your car is not equipped with an automatic antenna connection, connect this cable plus pole (+) to the ignition lock. An on/off switch should be inserted in this case. Make sure that this switch is turned off if the amplifier is not used.
