DEAR CUSTOMER,
We congratulate you on acquiring this MAC AUDIO Car HiFi Product.
Please read these instructions carefully so as to ensure optimum and disturbance-free functioning
of the appliance. Technical modifications reserved.
IMPORTANT INFORMATION TO BE HEEDED BEFORE INSTALLATION
· This device is only suitable for connection to a 12-volt system with negative earth.
· Ensure that the input cables are far enough away from the power supply cables, as this can otherwise
lead to interference. This also applies to the connecting cable for the remote control for regulating the
volume. This cable should not be laid on the side of the power supply leads but together with the audio
cable.
· Make sure that the fuse and controls are accessible after installation.
· The performance and reliability of the system depends on the quality of the installation. The system
should therefore be installed by a professional where several speakers or a complex multi-channel
system are involved.
POSITIONING AND SECURING THE SUBWOOFER
Place the subwoofer in a position where adequate ventilation of the amplifier module is guaranteed. Make
sure it rests on an even surface. The cone should not be placed directly against the car’s interior walls.
Make sure that the subwoofer is secured in such a way that it cannot slip or slide.
When securing the active subwoofer in place please make sure you do not damage any vehicle
cables, fuel lines, vacuum hoses or other such components.
Damage resulting from sudden changes in speed (e.g. hard braking) is not covered under the
terms of our guarantee. Use the securing device supplied for this purpose.
CONNECTING TO THE POWER SUPPLY (FIGURE 1, (1E))
Before installation: Remove the positive terminal from the car battery first in order to avoid short
circuiting.
Standard car wiring is normally not sufficient for the power requirement of the integrated amplifier.
Make sure that the wiring to the earth and +12V is of the correct gauge.
6 mm² cable
is the
minimum
requirement for the connection from the battery to the amplifier terminals (for long cable runs over 4
meters, 10 mm² gauge cable should be used).
First make the connection between the amplifier’s earth terminal (3) and the negative terminal on the
battery. To ensure a good connection, any residual dirt should first be carefully removed from the battery
terminals. A loose connection can result in malfunction or interference noise and distortions.
A power cable with an integrated fuse is then connected between the +12V (1) terminal on the amplifier
and the battery’s positive terminal. An additional fuse should be positioned at a maximum distance of 60
cm from the car battery. This is only to be inserted once all the installation work, including the connecting
of the speakers, has been completed.
Now connect the car radio’s +12v remote control cable (P-con, Power Antenna, or similar) to the REM
(2) control socket on the amplifier. A 0.75 mm² gauge cable is sufficient for this REMOTE connection.
The REMOTE input is not connected if the active subwoofer is activated by the speaker output of a car
radio or an amplifier, i.e. with high-level operation of the active subwoofer.
SELECTING LOW LEVEL/HIGH LEVEL CONNECTION WITH THE INPUT SWITCH (1C)
If the active subwoofer is connected to a control unit (car radio) with an RCA output jack (Line Out), the
input RCA jacks of the INPUT R/L are used.
