When this switch is set ON, undesirable ultra-low-frequency signals caused by turntable rumble or warped records can be eliminated without losing sound quality.

ON PURE DIRECT

Using the CD DIRECT AMP switch
For the best CD sound, set this switch so the indicator illuminates. The CD input signal is sent to a separate circuit, bypassing the INPUT selector, BASS, TREBLE, BALANCE and LOUDNESS controls, SUBSONIC FILTER switch (AX-592 and AX-892 only), and the PRE OUT/MAIN IN terminals (AX592 and AX-892 only) and then goes directly to the amplifier. This signal routing ensures the purest CD sound, eliminating any alterations to the original CD signals.

Using the MUTING switch

Selecting ON temporarily reduces the volume.
Note If both the CD DIRECT AMP and PURE DIRECT switches are on, only the CD DIRECT AMP switch will function.
WARNING When the LOUDNESS control has been set, if the PURE DIRECT switch or the CD DIRECT AMP switch is pressed, the sound will suddenly increase and may damage your ears or the speaker (the LOUDNESS control function may be bypassed). Therefore, only press the PURE DIRECT switch or the CD DIRECT AMP switch after lowering the volume or after checking that the LOUDNESS control is properly set.
