Yamaha AX-570 Owner's Manual - Page 9

ENGLISH 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 signal bypasses the BASS, TREBLE, BALANCE and LOUDNESS controls, eliminating any alterations to the audio signal. * Concerning AX-570 only, the SUBSONIC FILTER switch and the PRE OUT/MAIN IN terminals are also bypassed. PURE DIRECT Setting the PHONO switch 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. PHONO MC MM Setting the SUBSONIC FILTER switch If you set this switch to "ON" position, undesirable ultra-lowfrequency signals caused by turntable rumble or warped records can be cut out without losing sound quality. SUBSONIC FILTER ON OFF When you listen with headphones Connect the headphones to the PHONES jack. When listening with headphones privately, set both the SPEAKERS A and B switches to the OFF position.
