Using the CD DIRECT AMP switch
You can enjoy the purest possible CD sound from your CD
player by pressing this switch inward. By doing so, CD's input
signals are sent to the built-in amplifier special for CD directly
bypassing the input selector buttons, the 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.
Adjusting the continuously variable
LOUDNESS control
This control provides compensation for the human ears' loss of
sensitivity to high and low-frequency ranges at low volume.
This control is adjustable to retain full tonal range at any
volume level.
