GENERAL INFORMATION AF ASSY A SIDE B INPUT SIGNAL 10mV OUTPUT SIGNAL R85 – 1kΩ CONTROLL 0V, 5V or 12V CONNECT A POINT (GND) (FOUR PLACES) Single operation method and inputlevel. The procedure and the input level of a single operation are shown below. 1. R85 are shorted by 1kΩ. 2. A point of the figure below in four places is connected. GND is not common because it is independent with chassis GND (GND of the amplifier), B1GND, B2GND, and B3GND. The potential of B1GND, B2GND, and B3GND is done by connecting A point in four places as well as chassis GND. 2. The power supply of the product is turned on. 3. the terminal CONT (2 pin of CN3332) are controlled respectively by the following voltages. CONT 12V 5V 0V RY ON ON OFF MUTE OFF ON ON 4. The signal of 10mV is input from input terminal (JA3333), and the output is confirmed with speaker terminal (CN3331). Note : If the music signal is input directly to input terminal (JA3333) with CD PLAYER etc. , the output becomes a large volume because there are 40dB GAIN of the amplifier. Caution when disassemble. Even if the power supply code is pulled out from the outlet, neither C11 nor C12 of AF ASSY are discharged. Please discharge C11 and C12 of AF ASSY by the resistor of 100 Ω or more before removing AF ASSY or POWER SUPPLY ASSY. There is a possibility to destroy the transistor, and Please discharge by the resistor of 100 Ω or more. 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 M-IS21 18 ¶ SPECIFICATIONS 7 Amplifier Section Continuous average power output of 55 watts* per channel, min., at 6 ohms, from 60 Hz to 15,000 Hz with no more than 1.0 %** total harmonic dis- tortion. * Measured pursuant to the Federal Trade Commission’s Trade Regulation rule on Power Output Claims for Amplifiers. ** Measured by Audio Spectrum Analyzer. 7 Micellaneous Power Requirements ..........................................

GENERAL INFORMATION AF ASSY A SIDE B INPUT SIGNAL 10mV OUTPUT SIGNAL R85 – 1kΩ CONTROLL 0V, 5V or 12V CONNECT A POINT (GND) (FOUR PLACES) Single operation method and inputlevel. The procedure and the input level of a single operation are shown below. 1. R85 are shorted by 1kΩ. 2. A point of the figure below in four places is connected. GND is not common because it is independent with chassis GND (GND of the amplifier), B1GND, B2GND, and B3GND. The potential of B1GND, B2GND, and B3GND is done by connecting A point in four places as well as chassis GND. 2. The power supply of the product is turned on. 3. the terminal CONT (2 pin of CN3332) are controlled respectively by the following voltages. CONT 12V 5V 0V RY ON ON OFF MUTE OFF ON ON 4. The signal of 10mV is input from input terminal (JA3333), and the output is confirmed with speaker terminal (CN3331). Note : If the music signal is input directly to input terminal (JA3333) with CD PLAYER etc. , the output becomes a large volume because there are 40dB GAIN of the amplifier. Caution when disassemble. Even if the power supply code is pulled out from the outlet, neither C11 nor C12 of AF ASSY are discharged. Please discharge C11 and C12 of AF ASSY by the resistor of 100 Ω or more before removing AF ASSY or POWER SUPPLY ASSY. There is a possibility to destroy the transistor, and Please discharge by the resistor of 100 Ω or more. 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 M-IS21 18 ¶ SPECIFICATIONS 7 Amplifier Section Continuous Power (RMS) .................................. 100 W + 100 Wz (1 kHz, THD 10%, 6 Ω) Continuous Power (DIN) .......................................... 65 W + 65 W (1 kHz, THD 1%, 6 Ω) Music Power (DIN) .............................................. 150 W + 150 W (1 kHz, THD 1%, 6 Ω) ¶ Above specifications are for when the power supply is 230 V. 7 Micellaneous Power Requirements ..............................
