About This Product This product is a mono amplifier for subwoofer. If both L (left) and R (right) channels are connected to the RCA input of this product, output is mixed because this product is a mono amplifier. Before connecting/ installing the amplifier WARNING ! The use of a special red battery and ground wire RD-223, available separately, is recom- mended. Connect the battery wire directly to the car battery positive terminal + and the ground wire to the car body. ! This unit is for vehicles with a 12 V battery and negative grounding. Before installing in re- creational vehicles, trucks or buses, check the battery voltage. ! The black cable is ground. When installing this unit, make sure to connect the ground wire first. Ensure that the ground wire is prop- erly 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. ! Use a fuse of the rating prescribed. ! Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. Deter- mine and resolve the cause, then replace the fuse with identical equivalent. ! Always install the amplifier on a flat surface. Do not install the amplifier on a surface that is not flat or on a surface with a protrusion. Doing so could result in malfunction. ! When installing the amplifier, do not allow parts such as extra screws to get caught be- tween the amplifier and the automobile. Doing so could cause malfunction. ! Do not allow this unit to come into contact with liquids. Electrical shock could result. Also, damage to this unit, smoke, and over- heating could result from contact with liquids. The surfaces of the amplifier and any attached speakers may also heat up and cause minor burns. Before you start

English Section 01! In the event of any abnormality, the power supply to the amplifier is cut off to prevent equipment malfunction. If this occurs, switch the system power OFF and check the power supply and speaker connections. If you are un- able to determine the cause, please contact your dealer. ! Disconnect the negative terminal of the bat- tery before installation. CAUTION ! Always keep the volume low enough to hear outside sounds. ! Extended use of the car stereo while the en- gine is at rest or idling may exhaust the bat- tery. ! Connect either of two subwoofers to the am- plifier; 1: a subwoofer with a 350 W or larger nominal input and an impedance 4 W,or2:a subwoofer with a 600 W or larger nominal input and an impedance 2 W. If the nominal input and impedance are out of the above ranges, the subwoofer may catch fire, emit smoke or become damaged. Before you start

Section 01What’s what Front side Rear side To adjust the switch, use a flathead screwdri- ver if needed. 1 Power 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. If distortion occurs when the car stereo volume is turned up, turn these con- trols to higher level. ! For use with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. For use with an RCA equipped Pioneer car stereo, with max. output of 4 V or more, adjust level to match that of the car stereo output. ! If you hear too much noise when using the speaker input terminals, turn the gain control to higher level. 3 REMOTE (bass boost level remote con- trol) jack By connecting the Bass boost level remote control to the jack on the main unit, you will be able to select a bass boost level from 0 dB, 6 dB and 12 dB. For instruction of connecting the bass boost remote control to the amplifier, see the Con- nection diagram on page 7 . 4 LPF (low-pass filter) cut off frequency control You can select a cut off frequency from 40 Hz to 240 Hz. 5 INPUT (input) switch Input from either a car stereo external out- put (subwoofer output) or speaker output is possible. When using an external output (subwoofer output), select RCA. For connection instructions, refer to Connec- tion diagram on page 7. When using a speaker output, select SP and use the supplied speaker input wire with RCA pin cord. For details, refer to Connec- tions when using the speaker input wire on page 8. Setting gain properly ! Protective function included to prevent malfunction of the unit and/or speakers due to excessive output, improper use or improper connection. ! When outputting high volume sound etc., 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 impro- per 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. Setting the Unit

English Section 02! Despite correct volume and gain settings, the unit sound still cuts out periodically. In such cases, please contact the nearest authorized Pioneer Ser vice Station. Gain control of this unit Above illustration shows NORMAL gain set- ting. 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.
