[. . . ] Determine and resolve the cause, then replace the fuse with and identical equivalent. Also, damage to this unit, smoke, and overheating could result from contact with liquids. The surfaces of the amplifier and any attached speakers may also heat up and cause minor burns. [. . . ] 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 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. Relationship between amplifier gain and head unit output power En 5 Section 03 Connecting the units Connection diagram 2 9 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. A Connecting wire with RCA pin plugs (sold separately) Please see the following section for RCA input connection instruction. B External output c Car stereo with RCA output jacks (sold separately) d Speaker output terminals Please see the following section for speaker connection instructions. 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. B c 1 Special red battery wire RD-223 (sold separately) After completing all other amplifier connections, finally connect the battery wire terminal of the amplifier to the positive (+) battery terminal. Never ground speaker wire directly or band together multiple speakers’ negative (*) lead wires. 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. Install and route the separately sold battery wire, ground wire, speaker wires and the amplifier as far away as possible from the antenna, antenna cable and tuner. Avoid routing wires through hot areas, such as near the heater outlet.
