ADJUSTMENT 6. 1 IDLE CURRENT ADJUSTMENT ¶ CAUTION : Heatsinks' (Q323­Q326) DC level is equal to +B or -B. Don't touch them or you will be electric shocked. Connect the measuring instrument as shown in Fig. 6-1. (R373 or R374) Turn the POWER switch to ON. Adjust VR301 (VR302) so that the voltage between both sides of R373 (R374) becomes 10mV ± 1mV. Adjust VR301 (VR302) so that the voltage between both sides of R373 (R374) becomes 11mV ± 1mV.

On : The indicator lights: The signals passing 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 off: The signal passes through the various frequency adjusting circuits. 0 BASS tone control Use to adjust the low-frequency tone. The center position is the flat (normal) position. When turned to the right, low-frequency tones are emphasized; when turned to the left, low-frequency tones are de-emphasized. NOTE: This control does not operate when the DIRECT button is in the on position. - SPEAKERS B (ON/OFF) button/indicator Use this button to listen to the speaker system connected to SPEAKERS B terminals. No sound is heard from the speaker system. Set to this position when listening with headphones. 8 LOUDNESS button/indicator Use when listening at low volume levels. On : The indicator lights: Boosts low and high frequencies to give added punch to playback even at a low volume level. Off : The indicator goes off: Should normally be left in this position. NOTE: This button does not operate when the DIRECT button is in the on position. = PHONES jack When using headphones, insert the plug into this jack. NOTE: The speakers continue to output sound even when headphones are plugged into this jack. To mute the sound from the speakers, press the SPEAKERS button to OFF. 9 TREBLE tone control Use to adjust the high-frequency tone. The center position is the flat (normal) position.
