OPERATION ■ Adjusting the BASS and TREBLE controls The BASS and TREBLE controls adjust high and low frequency response. The center position produces a flat response. BASS When you feel there is not enough bass (low frequency sound), rotate clockwise to boost. When you feel there is too much bass, rotate counterclockwise to suppress. Control range: -10 dB to +10 dB (20 Hz) TREBLE When you feel there is not enough treble (high frequency sound), rotate clockwise to boost. When you feel there is too much treble, rotate counterclockwise to suppress. Control range: -10 dB to +10 dB (20 kHz) ■ Adjusting the BALANCE control The BALANCE control adjusts the sound output balance of the left and right speakers to compensate for sound imbalance caused by speaker locations or listening room conditions. ■ Adjusting the LOUDNESS control Retain a full tonal range at any volume level, thus compensating for the human ears' loss of sensitivity to high and low-frequency ranges at low volume. CAUTION If the PURE DIRECT switch is turned on with the LOUDNESS control set at a certain level, the input signals bypass the LOUDNESS control, resulting in a sudden increase in the sound output level. To prevent your ears or the speakers from being damaged, be sure to press PURE DIRECT switch AFTER lowering the sound output level or AFTER checking that the LOUDNESS control is properly set. 1 Set the LOUDNESS control to the FLAT position.
