[. . . ] 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. Determine and resolve the cause, then replace the fuse with and identical equivalent. Do not allow this unit to come into contact with liquids. [. . . ] 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 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. Above illustration shows NORMAL gain setting. 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. refer to Connecting the speakers and RCA input on page 8. 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. Secure the wiring with cable clamps or adhesive tape. 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. current capacity of the wire is limited. 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 shorten any wires, the protection circuit may malfunction. Never ground speaker wire directly or band together multiple speakers’ negative (*) lead wires. [. . . ] 1 Lug (sold separately) 2 Speaker wire 3 Connect the speaker wires to the speaker output terminals. Fix the speaker wires securely with the terminal screws. 10 En Section Installation Before installing the amplifier WARNING !To ensure proper installation, use the supplied parts in the manner specified.
