Using the PURE DIRECT switch
You can enjoy the purest possible sound from your audio
sources by setting this switch so that the indicator lights up. By
doing so, the audio signals bypass the BASS, TREBLE,
BALANCE, LOUDNESS controls, SUBSONIC FILTER switch,
MODE switch and the PRE OUT/MAIN IN terminals, thus
eliminating any alterations to the audio signals. Select either MM or MC position depending on your PHONO
cartridge, Moving Magnet or Moving Coil type. However, if you
use a high output MC cartridge, select MM position.
To select the MC position, press this switch so that it is held
inward. To select the MM position, press this switch so that it is
released outward.
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.
