MW1000A - Subwoofer Musway - Free user manual and instructions

USER MANUAL MW1000A Musway

• This device is only suited for a 12 volt system with negative ground.

• Ensure that the input and output cables are sufciently separated from the power supply cables. Otherwise interferences may occur.

• Ensure the accessibility of the fuse and the operating elements after installation.

• The reliability and performance of the amplier depends on the quality of installation. Preferably consult an expert to install the system.

• Avoid any damage or removing of the components of the vehicle like wires, cables, board computer, seat belts, gas tank or the like.7 INTERCONNECTION ATTENTION: Before you start with the installation, disconnect the ground connection from the ve- hicle’s battery in order to prevent short circuits. Use the enclosed cable plug to connect each terminal. First connect the GND terminal of the amplier to an appropriate ground connection at the chassis. To ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause malfunctions or interferences noise and distortion. Then connect the +12 V terminal of the amplier with the battery by using an appropriate cable including an in-line fuse. This fuse should be located very close to the battery; for safety reasons not more than 30 cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been ac- complished. CAUTION: Never use the high level inputs and the RCA inputs at the same time. This may damage the device seriously. Use the enclosed cable plug to connect each terminal.

Then turn the volume controller of the head unit to 80 - 90% of its full setting. Now turn INPUT LEVEL clockwise until you hear some distortion. Then turn back INPUT LEVEL slightly until you hear a cleaner sound.

By using the BASS BOOST controller you are able to increase the bass enhancement from 0 to 12 dB. ATTENTION: Use the BASS BOOST wisely!

VARIABLE LOW PASS FILTER

Set the desired crossover frequency by using the controller LOW PASS. Thus to that only the frequencies below the chosen crossover frequency will be amplied and the subwoofer plays more precisely and efcient. PHASE SWITCH The PHASE switch allows to switch the phase from 0° to 180° to match the output signal with the vehicle’s interior acoustic. INPUT LEVEL

MW1000A BASS BOOST LOW PASS PHASE PROTECTION CIRCUIT The PWR LED lights up green, if the amplier is in operation. The PRO LED lights up red, when the amplier is overheated, or a short circuit occurs respective a too low impedance load is connected to the speaker outputs. If this events, the internal built-in protection circuit shuts down the amplier automatically. The amplier should work again properly after you have solved the problems. Troubleshooting

• Check all connections for defects or short circuits and correct them.
