Turn the hum canceller on/off. If this is turned off, the fol-
lowing items will not be displayed.
Freq (Frequency)
Hum will be removed at the specified frequency and at
multiples of that frequency. Set it to match the frequency of
your power supply.
Width
Specify the width of the filter which will remove the hum.
Depth
Specify the depth of the filter which will remove the hum.
Thresh (Threshold)
Adjust the level at which the hum canceller will begin to
take effect. If the signal falls below the specified level, only
the hum will be removed from the signal. With the maxi-
mum setting, hum will always be removed regardless of the
level of the signal.
RngL (Range low)
Specify the lower limit of the frequency range in which the
hum canceler will operate. With a setting of Unlimit, the
limit will be the lowest frequency that the VS-880 is capable
of playing back.
RngH (Range high)
Specify the upper limit of the frequency range in which the
hum canceller will operate. With a setting of Unlimit, the
limit will be the highest frequency that the VS-880 is capable
of Playing back.

Vocal Canceller
When a stereo source is being input from CD or DAT etc.,
this cancels the sound which is located in the stereo center,
such as the vocal or bass.
Input L
Vocal Canceler
Input R
* Depending on the musical source, sounds that you do not
wish to be canceled may be canceled as well. In particular
if the musical source has heavy reverb or if the sound that
you wish to delete is not located in the center, the vocal
canceller may not produce the desired result.

VclCancel (Vocal canceller)
Turn the vocal canceller on/off. If this is turned off, the fol-
lowing items will not be displayed.
Balance
If the sound that you wish to cancel is not located in the
center, find the point at which it is most effectively can-
celed.
RngL (Range low)
Specify the lower limit of the frequency range from which
you wish to cancel a sound. Use this setting when you wish
to decrease the volume of the vocal without affecting a low-
frequency instrument (such as bass) located in the center.
With a setting of Unlimit, the lowest frequency which the
VS-880 is capable of Playing back will be the lower limit.
RngH (Range high)
Specify the upper limit of the frequency range from which
you wish to cancel a sound. Use this setting when you wish
to decrease the volume of the vocal without affecting a
high-frequency instrument located in the center. With a set-
ting of Unlimit, the highest frequency which the VS-880 is
capable of Playing back will be the upper limit.
