OPERATIONS AND SPECIFICATIONS 8.1 OPERATIONS 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 back 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 ouput level. Power Indicator The power indicator lights when the power is switched on. Bass Boost Level Control Bass boost level control can boost the level around the frequency selected by the bass boost frequency control from 0 to 18 dB. Cut Off Frequency Control If the LPF/HPF select switch is set to LPF (or HPF), you can select a cut off frequency from 50 to 120 Hz. LPF (Low-Pass Filter)/HPF (High-Pass Filter) Select Switch Set the LPF/HPF select switch as follows according to the type of speak- er that is connected to the speaker output connector and the car stereo system: LPF/HPF Select Audio frequency range Speaker Remarks Switch to be output Type LPF (left) * — 50 to 120 Hz Sub-woofer Connect a sub-woofer. OFF (center) Full range Full range HPF (right) * 50 to 120 Hz — Full range 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. Bass Boost Frequency Control (PRS-X720 and PRS-X320) You can select a bass boost frequency from 40 to 120 Hz with the bass boost control. • Bass Boost Level Control and Bass Boost Frequency Control can be adjusted only when the LPF/HPF select switch is set to a position other than HPF. Subsonic Select Switch (PRS-X720 and PRS-X320) The subsonic filter cuts inaudible fre- quencies below 15 Hz to eliminate unwanted vibrations and minimize power loss. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 52 PRS-X720,X320,X220 Connection Diagram Connecting the Unit Fuse (30 A) × 3 Grommet RCA input Special red battery wire After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery.

Amplifier with RCA input jacks PRS-X720: Fuse (30 A) × 3 PRS-X320: Fuse (30 A) × 2 PRS-X220: Fuse (30 A) × 1 Car stereo with RCA output jacks External Output Connecting wires with RCA pin plugs (sold separately). RCA input jack RCA output jack Speaker output terminal See the “Connecting the Speaker wires” section for speaker connection instructions. System remote control wire (sold separately). Connect the male terminal of this wire to the system remote con- trol terminal of the car stereo (SYSTEM REMOTE CONTROL). The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch. Reverse side [RD-223] (sold separately) Cannot be used with the PRS-X220. [RD-222] (sold separately) Cannot be used with the PRS-X320. To prevent damage • Do not ground the speaker wire directly or con- nect a negative (–) lead wire for several speakers. • This unit is for vehicles with a 12-volt battery and negative grounding. Before installing it in a recre- ational vehicle, truck, or bus, check the battery voltage. • If the car stereo is kept on for a long time while the engine is at rest or idling, the battery may go dead. Turn the car stereo off when the engine is at rest or idling. • If the system remote control wire of the amplifier is connected to the power terminal through the ignition switch (12 V DC), the amplifier will always be on when the ignition is on— regardless of whether the car stereo is on or off. Because of this, the battery could go dead if the engine is at rest or idle. • Install and route the separately sold battery wire as far away as possible from the speaker wires. Install and route the separately sold battery wire and ground wire, speaker wires, and the amplifier as far away as possible from the antenna, antenna cable and tuner. • Cords for this product and those for other prod- ucts may be different colors even if they have the same function. When connecting this product to another product, refer to the supplied Installation manuals of both products and connect cords that have the same function. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com PRS-X720,X320,X220 53 8.2 SPECIFICATIONS Power source.............................................................................................................. 14.4 V DC (10.8 — 15.1 V allowable) Grounding system ............................................................................................................................................
