ADJUSTMENT - Setting Idle Current The following is the instructions for setting Idle current: Setting the idle current to the following ranges will require you to measure the voltage across the indicated resistors and adjusting the indicated variable resistors to set the required voltage range. This adjustment is performed with no loads on the outputs with no signal input. Specification: 45 mA ± 5mA Voltage Range: 4.0 mV to 5.0 mV 1. Measure voltage across Resistor R433 and set VR501 to Voltage Range. 2. Measure voltage across Resistor R434 and set VR502 to Voltage Range. 3. Measure voltage across Resistor R435 and set VR503 to Voltage Range. 4. Measure voltage across Resistor R436 and set VR504 to Voltage Range. Notes: The Idle current should be set when the amplifier has not been run for awhile, and set at room temperature. 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-X340 7.

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. Power Indicator The power indicator lights when the power is switched on. RCA Input Select Switch For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right. Cut Off Frequency Control Combining LPF/HPF/BPF and LOW/HIGH select switch settings lets you select between cut off frequencies from 40 to 120 Hz and 3k to 9k Hz. (Example: LPF and HIGH) 0 -3 (dB) (Hz) (3 kHz) (9 kHz) LPF (Low-Pass Filter)/HPF (High-Pass Filter)/BPF (Band-Pass Filter) and LOW/HIGH Select Switch Set the LPF/HPF/BPF and LOW/HIGH 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/BPF Audio frequency range Speaker Remarks and LOW/HIGH to be output Type Select Switch LPF HIGH — 3k to 9k Hz Mid Connect a mid range speaker. LOW — 40 to 120 Hz Subwoofer Connect a subwoofer. HPF HIGH *2 3k to 9k Hz — Tweeter*3 Connect a tweeter. LOW 40 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. BPF (for CH A)*4 40 to 120 Hz — Mid Connect a mid range speaker. — 3k to 9k Hz OFF Full range Full range *2 With CH A, even if the setting is HPF-HIGH, you can only select the same cut off frequency as with HPF-LOW (40 to 120 Hz). *3 If you connect the tweeter directly, you must set the CH B to HPF-HIGH. *4 Be sure to set the LOW/HIGH select switch to HIGH.
