Using the PURE DIRECT switch
You can enjoy the purest possible sound from your audio
sources by setting this switch so that the indicator illuminates.
By doing so, the audio signals bypass the BASS, TREBLE,
BALANCE and LOUDNESS controls, thus eliminating any
alterations to the audio signals.
*
The SUBSONIC FILTER switch and the PRE OUT/MAIN
IN terminals are also bypassed.
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.
*
The SUBSONIC FILTER switch and the PRE OUT/MAIN
IN terminals are also bypassed.
Note
If both the CD DIRECT and PURE DIRECT switches are on,
only the CD DIRECT switch will function.
If you set this switch to “ON” position, undesirable ultra-low-
frequency signals caused by turntable rumble or warped
records can be cut out without losing sound quality.
