PLAYING AND RECORDING Adjusting the tonal quality ■ Adjusting 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. BALANCE 0 1 1 2 2 3 3 4 L5 4 5R ■ Using the PURE DIRECT button Routes input signals from your audio sources so that the input signals bypass the BASS, TREBLE, BALANCE and LOUDNESS controls, thus eliminating any alterations to the audio signals and creating the purest possible sound. PURE DIRECT ■ Adjusting the LOUDNESS control Retains a full tonal range at any volume level, thus compensating for the human ears' loss of sensitivity to high and low-frequency ranges at a low volume level. CAUTION If the PURE DIRECT button 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 undesirably damaged, be sure to press the PURE DIRECT button AFTER lowering the sound output level or AFTER checking that the LOUDNESS control is properly set. 1 Rotate the LOUDNESS control on the front panel to the FLAT position.
