MAN-PRS-D400-GB.fm Page 3 Tuesday, February 21, 2006 3:43 PM Before Using This Product ! CAUTION Diagram A - Proper 8 Ohm Speaker WARNING Diagram B - Improper 4 Ohm Speaker · 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. 8 Ohm Speaker 4 Ohm Speaker L+ R- L+ R- Pioneer Amplifier 4 Ohm Bridged Mode Pioneer Amplifier 2 Ohm Bridged Mode · 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. · DO NOT allow amplifier to come into contact with liquids due to, for example, the location where the amplifier is installed. Electrical shock could result. Also, amplifier and speaker damage, smoke, and overheating could result from contact with liquids. In addition, the amplifier surface and the surface of any attached speakers could become hot to the touch and minor burns could result. 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. If you have any questions or concerns, please contact your local authorized Pioneer dealer or call Pioneer customer service. 3 ENGLISH MAN-PRS-D400-GB.fm Page 4 Tuesday, February 21, 2006 3:43 PM Setting the Unit Terminal Cover Before setting up the unit, unfasten the screws with a 4 mm hexagonal wrench and remove the terminal cover. 4 LPF (Low-Pass Filter)/HPF (High-Pass Filter) Select Switch ENGLISH Set the LPF/HPF select switch as follows according to the type of speaker that is connected to the speaker output connector and the car stereo system: LPF/HPF Select Switch LPF (Left) OFF (Center) HPF (Right) Audio frequency range to be output * ­ 40 Hz to 120 Hz Full range * 40 Hz to 120 Hz ­ Speaker Type Subwoofer Full range Full range Remarks Connect a subwoofer. Use if you want to cut the very low frequency range* because it is not necessary for the speakers you are using. * See the "Cut Off Frequency Control" section. Input Select Switch For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right. Power Indicator Cut Off Frequency Control If the LPF/HPF select switch is set to LPF or HPF, you can select a cut off frequency from 40 Hz to 120 Hz. The power indicator lights when the power is switched on. Gain Control Input Switch It is possible to input from a car stereo external output (subwoofer output) or a car stereo speaker output. When using an external output (subwoofer output), slide the switch to the left. For connection instructions, see the "Connection Diagram" section. When using a speaker output, slide the switch to the right. In this case, it is necessary to use the supplied speaker input wire with RCA pin cord. For details, see the "Using the Speaker Input" section. Adjusting the gain controls A and B will help match the output of the car stereo to the Pioneer amplifier. Normally, set the gain controls to the NORMAL position. If the output is low, even when the volume of the car stereo is turned up, turn these controls clockwise. If there is distortion when the volume of the car stereo is turned up, turn these controls counter-clockwise. · If you only use one input plug, set the gain controls for speaker outputs A and B to the same position. · 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. BFC (Beat Frequency Control) Switch BFC switch is on the bottom of the unit. If you hear a beat while listening to an MW/LW broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver. MAN-PRS-D400-GB.fm Page 5 Tuesday, February 21, 2006 3:43 PM Connecting the Unit ! CAUTION · Disconnect the negative (­) terminal of the battery to avoid the risk of short-circuit and damage to the unit. · Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap adhesive tape around it where they lie against metal parts. · Do not route wires where they will get hot, for example where the heater will blow over them. If the insulation heats up, it may become damaged, resulting in a short-circuit through the vehicle body. · Make sure that wires will not interfere with moving parts of the vehicle, such as the gearshift, handbrake or seat sliding mechanism. · Do not shorten any wires. Otherwise the protection circuit may fail to work when it should. · Never feed power to other equipment by cutting the insulation of the power supply wire to tap from the wire. The current capacity of the wire will be exceeded, causing overheating. · 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. Connection Diagram · This diagram shows connections using external output (subwoofer output). Slide the input switch to the left. · When you connect with speaker output, connections defers from the diagram. For details, see the "Using the Speaker Input" section. In either case, you need to set the input switch. For details, see the "Setting the Unit" section.
