User manual PIONEER GM-7200M

[. . . ] Otherwise you may get an electric shock. Also, do not touch the amplifier when it is wet. For traffic safety and to maintain safe driving conditions, keep the volume low enough so that you can still hear normal traffic sound. Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. [. . . ] Use if you want to cut the very low frequency range* because it is not necessary for the speakers you are using. If the LPF/HPF select switch is set to LPF or HPF, you can select a cut off frequency from 40 to 120 Hz. To protect the wiring, wrap adhesive tape around it where they lie against metal parts. Do not route wires where they will get hot, for example where the heater will blow over them. If the insulation heats up, it may become damaged, resulting in a short-circuit through the vehicle body. Make sure that wires will not interfere with moving parts of the vehicle, such as the gearshift, handbrake or seat sliding mechanism. Otherwise the protection circuit may fail to work when it should. Never feed power to other equipment by cutting the insulation of the power supply wire to tap from the wire. After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. Always use the special red battery and ground wire [RD-223], which is sold separately. Fix the wires securely with the terminal screws. Connect the speaker leads to suit the mode according to the figures shown below. Do not connect both the RCA input and the speaker input at the same time. Example of installation on the floor mat or on the chassis Insert the supplied tapping screws (4 × 18 mm) into the screw holes. Push on the screws with a screwdriver so they make marks where the installation holes are to be located. 1 kg (Leads for wiring not included) Maximum power output . Cut off frequency: 40 -- 120 Hz Cut off slope: ­12 dB/oct High pass filter . Cut off frequency: 40 -- 120 Hz Cut off slope: ­12 dB/oct Maximum input level/impedance . Do not install in: --Places where it could injure the driver or passengers if the vehicle stops suddenly. --Places where it may interfere with the driver, such as on the floor in front of the driver's seat. Make sure that wires are not caught in the sliding mechanism of the seats, resulting in a short-circuit. Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. [. . . ] If any parts other than the supplied ones are used, they may damage internal parts of the amplifier, or they may become loose causing the amplifier to shut down. (Left) Speaker out B (Right) Input Select Switch For two-channel input, slide this switch to the left. Specifications and the design are subject to possible modification without notice due to improvements. To ensure proper heat dissipation of the amplifier, be sure of the following during installation. [. . . ]
