Before Using This Product
BRIDGEABLE POWER AMPLIFIER AMPLIFICADOR DE POTENCIA EN PUENTE
Thank you for purchasing this PIONEER product. Before attempting operation, be sure to read this manual. If you have any questions or concerns, please contact your local authorized Pioneer dealer or call Pioneer customer service.

Setting the Unit
Gain Control
If the sound level is too low, even when the volume of the car stereo used along with this power amplifier is turned up, turn gain control on the front of the power amplifier clockwise. If the sound distorts when the volume is turned up, turn the gain control counter-clockwise.
� When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level. � If you hear too much noise when using the speaker input terminals, turn the gain control counter-clockwise.

Power Indicator
The power indicator lights when the power is switched on.

In case of trouble
When the unit does not operate properly, contact your dealer or the nearest authorized PIONEER Service Station.

WARNING
� Always use the special red battery and ground wire [RD-223], which is sold separately. Connect the battery wire directly to the car battery positive terminal (+) and the ground wire to the car body. � Do not touch the amplifier with wet hands. Otherwise you may get an electric shock. Also, do not touch the amplifier when it is wet. � For traffic safety and to maintain safe driving conditions, keep the volume low enough so that you can still hear normal traffic sound. � Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. Detect the cause and solve the problem, then replace the fuse with another one of the same size and rating. � To prevent malfunction of the amplifier and speakers, the protective circuit will cut the power supply to the amplifier (sound will stop) when an abnormal condition occurs. In such a case, switch the power to the system OFF and check the connection of the power supply and speakers. Detect the cause and solve the problem. � Contact the dealer if you cannot detect the cause. � To prevent an electric shock or short-circuit during connection and installation, be sure to disconnect the negative (�) terminal of the battery beforehand. � Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. Be sure to protect all cables and important equipment such as fuel lines, brake lines and the electrical wiring from damage.

CAUTION

BFC (Beat Frequency Control) Switch
If you hear a beat while listening to an AM broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver.

Owner�s Manual

Never replace the fuse with one of greater value or rating than the original fuse. Use of an improper fuse could result in overheating and smoke and could cause damage to the product and injury including burns.

Do NOT install or use your Pioneer amplifier by wiring speakers rated at 4 Ohm (or lower) in parallel to achieve a 2 Ohm (or lower) bridged mode (Diagram B). Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier surface could also become hot to the touch and minor burns could result. To properly install or use a bridged mode for a two-channel amplifier and achieve a 4 � load, wire two 8 � speakers in parallel with Left + and Right - (Diagram A) or use a single 4 � speaker. For a four-channel amplifier, follow the speaker output connection diagram for bridging as shown on the back of your amplifier, and wire two 8 � speakers in parallel to achieve a 4 � load or use a single 4 � speaker per channel.
