The gain is also adjusted appropriately for CD so that the purest possible sound is reproduced without any alterations to the CD signals. Lights up ■ Adjusting the BALANCE control Adjust the sound output balance of the left and right speakers to compensate for sound imbalance caused by speaker locations or listening room conditions. Notes • The BASS, TREBLE, BALANCE, LOUDNESS controls and INPUT selector do not function while the CD DIRECT AMP switch is turned on. € Be sure to connect the CD player to the CD input jacks if you use the CD DIRECT AMP switch. 10 En PLAYING AND RECORDING ■ 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 CD DIRECT AMP switch (or 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 the CD DIRECT AMP switch (or the PURE DIRECT switch) AFTER lowering the sound output level or AFTER checking that the LOUDNESS control is properly set.
