OPERATION 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 1 2 3 4 L5 1 2 3 4 5R ■ Using the CD/DVD DIRECT AMP switch Routes input signals from your CD or DVD player directly to the specially built-in amplifier for the CD or DVD player. As a result, the input signals bypass the INPUT selector and the BASS, TREBLE, BALANCE and LOUDNESS controls (and the TAPE MONITOR switch for AX-397 only) and then sent to the power amplifier, thus eliminating any alterations to the CD or DVD signals and creating the purest possible sound. Lights up CD/DVD DIRECT AMP PLAYING AND RECORDING ■ 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 low volume. CAUTION If the CD/DVD DIRECT AMP switch (or the PURE DIRECT switch for AX-497 only) 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 CD/DVD DIRECT AMP switch (or the PURE DIRECT switch for AX-497 only) 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. LOUDNESS 1 FLAT -30dB 2 10 3 9 4 8 567 ■ Using the PURE DIRECT switch (AX-497 only) Routes input signals from your audio sources. As a result, 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. Lights up PURE DIRECT Note As for AX-497 only, if both the CD/DVD DIRECT AMP and the PURE DIRECT switches are turned on, only the CD/DVD DIRECT AMP switch will function. ■ Adjusting the BASS and TREBLE controls Adjusts the high and low frequency response. BASS Increases or decreases the low frequency response. TREBLE Increases or decreases the high frequency response.
