SAFETY INFORMATION This service manual is intended for qualified service technicians ; it is not meant for the casual do-it- yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician. WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health the cassette deck will be disconnected, improving sound quality. NOTE: The function selected using the INPUT SELECTOR knob will be recorded irrespective of the position of the REC SELECTOR switch (TAPE 2 MONITOR terminals). 8BALANCE control Should normally be left in the center position. Adjust the balance if the sound is louder from one of the speakers. If the right side is louder, turn toward the L (left) position and if the left side is louder, turn toward the R (right) position. NOTE: This control does not operate at DIRECT ON mode. 9DIRECT/SB MODE button/indicator Press and hold the button for more than 3 seconds to switch SB mode ON. (Volume indicator goes out) Press and hold the button for more than 3 seconds again to switch SB mode OFF. (Volume indicator lights) DIRECT Use this button when you do not wish to pass the output from input terminal equipment through the various frequency adjust- ing circuits (BASS, TREBLE, BALANCE, LOUDNESS). On: The indicator lights. The signals input through the input terminals are reproduced without passing through the various frequency adjusting circuits. This results in flat, pure sound which is a more faithful reproduction of the input source. Off: The indicator goes out. The signal passes through the various frequency adjusting circuits. SB MODE The SB mode is a special mode in which the amplifier does not accept remote control except power ON/OFF (But all of the fa- cilities can be controled by manual as same as SB mode OFF.). Fix the VOLUME control near the center position.In this mode, the set can be used as a power amplifier which amplifies the LINE/SURROUND BACK input (the function name is LINE/SB) with a input sensitivity of 1V. For example, when the set is combined with one of Pioneers Surround Back compatible receiver, the set can be used sa the Surround Back amplifier. (For details, please refer to the instruction manual of the receiver.) 0LOUDNESS button/indicator Use when listening at low volume level. On: The indicator lights. Boosts low and high frequencies to give added punch to playback even at low volume level. Off: The indicator goes out. Should normally be left in this position. NOTE: This button does not operate at DIRECT ON mode. -TREBLE tone control Use to adjust the high-frequency tone. The center position is the flat (normal) position. When turned to the right, the high-frequency tone is emphasized; when turned to the left, the high-frequency tone is de-emphasized. NOTE: This control does not operate at DIRECT ON mode. =BASS tone control Use to adjust the low-frequency tone. The center position is the flat (normal) position. When turned to the right, the low-frequency tone is emphasized; when turned to the left, the low-frequency tone is de-emphasized. NOTE: This control does not operate at DIRECT ON mode. PHONES jack When using headphones, insert the plug into this jack. !SPEAKERS B (ON/OFF) button/indicator Use this button to listen to the speaker system connected to the SPEAKERS B terminals. On: The indicator lights. Sound is heard from the speaker sys- tem. Off: The indicator goes out. No sound is heard from the speaker system. Set to this position when listening with headphones. SPEAKERS A (ON/OFF) button/indicator Use this button to listen to the speaker system connected to the SPEAKERS A terminals. On : The indicator lights. Sound is heard from the speaker sys- tem. Off : The indicator goes out. No sound is heard from the speaker system. Set to this position when listening with headphones. 28 A-509R SIGNAL GND PHONOTUNERLINE/ SURROUND BACK TAPE1/CD-R/MDTAPE2 MONITOR CD IN IN IN IN OUT IN OUT IN REC PLAY REC PLAY L R L R R R L L B A SPEAKERS CONTROL OUT AC OUTLET SWITCHED 100W MAX AC INLET 0SPEAKERS B terminals (Right channel) -SPEAKERS B terminals (Left channel) =AC INLET jack Connect one end of the power cord to here and the other end to an AC wall socket, or the AC outlet of an audio timer.
