User manual PIONEER GM-D8604

[. . . ] 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. Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. [. . . ] Gain control of this unit Preout level: 2 V (Standard: 500 mV) 02 English Preout level: 4 V Above illustration shows NORMAL gain setting. 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. 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. en 5 Section 03 Connecting the units Connection diagram 7 8 2 3 6 4 5 9 d 1 c a b h i g f e 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 (80 A) (sold separately) Each amplifier must be separately fused at 80 A. 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 If only one input plug is used, do not connect anything to RCA input jack B. 9 Connecting wire with RCA pin plugs (sold separately) a RCA input jack A b RCA input jack B c Amplifier with RCA input jacks (sold separately) d RCA output jack Outputs the signal input to CH A. E Speaker output terminals Please see the following section for speaker connection instructions. 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 Fuse (30 A) × 2 h Front side i Rear side Note INPUT SELECT (input select) switch must be set. To protect the wiring, wrap sections in contact with metal parts in adhesive tape. Never cut the insulation of the power supply to feed power to other equipment. 6 En Section Connecting the units In addition, refer to the speaker instruction manual for information on the correct connection procedure. For any further enquiries, contact your local authorized Pioneer dealer or customer service. If the system remote control wire of the amplifier is connected to the power terminal via the ignition switch (12 V DC), the amplifier will remain on with the ignition whether the car stereo is on or off, which may exhaust battery if the engine is at rest or idling. Install and route the separately sold battery wire as far as possible from the speaker wires. [. . . ] 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. 3 Install the amplifier with the use of supplied tapping screws (4 mm × 18 mm). To ensure proper heat dissipation of the amplifier, ensure the following during installation: — Allow adequate space above the amplifier for proper ventilation. [. . . ]
