Using the PURE DIRECT switch
You can enjoy the purest possible sound from your sources by
setting this switch so that the indicator illuminates. The signals
bypass the BASS, TREBLE, BALANCE and LOUDNESS
controls, the SUBSONIC FILTER switch ( AX-592 and AX-892
only ), and the PRE OUT/MAIN IN terminals ( AX-592 and AX-
892 only ), eliminating any alterations to the signals.
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 ( AX-
592 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.
CD DIRECT AMP
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.
Setting the SUBSONIC FILTER switch
AX-592 and AX-892 only
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.
