HumCancel (Hum canceller)

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.

NS (Noise suppressor)

NoiseSup	Off, On
Thresh	0Ð100
Release	0Ð100

Thresh (Threshold)

Adjust the level at which the noise suppressor will begin to operate.

Release

●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.

*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.

VC (Vocal canceller)

VclCancel	Off, On
Balance	0Ð100
RngL	Unlimit, 20Ð2000 Hz
RngH	1.0Ð20.0 kHz, Unlimit

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.
