By doing so, the audio signals bypass the BASS, TREBLE, BALANCE and LOUDNESS controls, thus eliminating any alterations to the audio signals. AX-590 only * The SUBSONIC FILTER switch and the PRE OUT/MAIN IN terminals are also bypassed. Using the CD DIRECT AMP switch You can enjoy the purest possible CD sound from your CD player by setting this switch so that the indicator illuminates. By doing so, CD's input signals are sent to the built-in amplifier special for CD directly bypassing the INPUT selector, BASS, TREBLE, BALANCE and LOUDNESS controls, and then sent to the power amplifier. This signal routing reproduces the purest CD sound eliminating any alterations to the CD signals.
