User manual PIONEER GM-D9601

[. . . ] Ensure that the ground wire is properly connected to metal parts of the car’s body. The ground wire of the one of this unit must be connected to the car separately with different screws. If the screw for the ground wire loosens or falls out, it could result in fire, generation of smoke or malfunction. The use of an improper fuse could result in overheating and smoke, damage to the product and injury, including burns. [. . . ] 1 POWER/PROTECT indicator The power indicator lights up to indicate power ON. 2 GAIN (gain) control If output remains low, even when the car stereo volume is turned up, turn controls to lower level. Protective function included to prevent malfunction of the unit and/or speakers due to excessive output, improper use or improper connection. , this function cuts off the output for a few seconds as a normal function, but output is restored when the volume of the head unit is turned down. A cut in sound output may indicate improper setting of the gain control. To ensure continuous sound output with the head unit at a high volume, set amplifier gain control to a level appropriate for the preout maximum output level of the head unit, so that volume can remain unchanged and to control excess output. Despite correct volume and gain settings, the unit sound still cuts out periodically. in such cases , please contact the nearest authorized Pioneer Service Station. Gain control of this unit Preout level: 2 V (Standard: 500 mV) 02 English Signal waveform when outputting at high volume using amplifier gain control Signal waveform distorted with high output, if you raise the gain of the amplifier the power changes only slightly. Relationship between amplifier gain and head unit output power If amplifier gain is raised improperly, this will simply increase distortion, with little increase in power. en 5 Section 03 Connecting the units Connection diagram 7 2 3 6 4 5 9 8 b c a 1 e h d i j f g 1 Battery wire (sold separately) !The maximum length of the wire between the fuse and the positive + terminal of the battery is 30 cm. The battery wire, the ground wire and the optional direct ground wire must be same size. After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive + terminal of the battery. 2 Fuse 100 A (GM-D8601) / 150 A (GM-D9601) (sold separately) Each amplifier must be separately fused at 100 A (GM-D8601) / 150 A (GM-D9601). 3 Positive (+) terminal 4 Negative (*) terminal 5 Battery (sold separately) 6 Ground wire, Terminal (sold separately) The ground wires must be same size as the battery wire. 7 Car stereo with RCA output jacks (sold separately) 8 External output 9 Connecting wire with RCA pin plugs (sold separately) a Amplifier with RCA input jacks (sold separately) b Bass boost level remote control c Bass boost level remote control wire (5 m) d RCA input jack e RCA output jack f System remote control wire (sold separately) Connect male terminal of this wire to the system remote control terminal of the car stereo. The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo lacks a system remote control terminal, connect the male terminal to the power terminal via the ignition switch. G Speaker output terminals Please see the following section for speaker connection instructions. h Fuse 40 A × 2 (GM-D8601) / 40 A × 3 (GMD9601) i Front side j Rear side Before connecting the amplifier WARNING !To protect the wiring, wrap sections in contact with metal parts in adhesive tape. [. . . ] Insert the supplied tapping screws (4 mm × 18 mm) into the screw holes and push on the screws with a screwdriver so they make an imprint where the installation holes are to be located. 5 mm diameter holes at the imprints either on the carpet or directly on the chassis. To ensure proper heat dissipation of the amplifier, ensure the following during installation: — Allow adequate space above the amplifier for proper ventilation. Place all cables away from hot places, such as near the heater outlet. [. . . ]
