JVP UserÕs Manual21 Understanding Equalization
The diagram below shows how analog hardware can be conÞgured to do
the de-essing job.
JVP uses a digital algorithm to implement the de-esser function. While the
details of the algorithm are quite complex, the diagram above illustrates the
functional relationships for the purposes of explanation. The details of using
the de-esser Õs controls are explained in ÒThe De-esserÓ on page 33.

thereby correcting the errors to a high degree. JVPÕs equalizer gives perfor-
mance unsurpassed by any DSP based equalizer in existence today.
Filter Types
JVPÕs equalizer contains Þve different Þlter types: Low Pass, Low Shelf,
Peak/Notch, High Shelf, High Pass. Each Þlter type has its own characteris-
tics and applications. The graphs used in the next section show the fre-
quency response for each type with the settings used to generate the curves
notated next to the...

a true 140 dB dynamic range, they are especially useful for mastering stereo
Þles.
Peak/Notch Filters
JVPÕs peak/notch Þlters are useful in shaping the tone of solo instruments
and complete mixes. Beside having a 140 dB dynamic range, their control
ranges are also extraordinarily broad. The range of frequencies over which
the Þlter has effect is called the bandwidth of the Þlter. The bandwidth of
JVPÕs Þlters can be adjusted from between 0.1 to 4.0 octaves....

The graphs below show the effect of changing the bandwidth control of a
peak/notch Þlter. 
Note: The bandwidth of the Þlter is the number of octaves included
between the ±3 dB points on either side of the Þlter Õs center frequency.
Shelving Filters
Shelving Þlters are used as primarily as Òtone controlsÓ, cutting or boosting
whole regions of the spectrum. A high shelf Þlter, for instance, acts by rais-
ing or lowering the part of the spectrum above the cutoff...

JVP UserÕs Manual25 What Is A Multi-Tap Delay?
The graphs below show the response of the high shelf and low shelf Þlters
at +12 dB gain. Notice that the slope of the roll-off is 6 dB per octave.
What Is A Multi-Tap Delay?
Delay effects are often used to thicken or ÒfattenÓ a solo voice or instrumen-
tal track. This thickening occurs because a copy or copies of the sound are
delayed and added to the original, creating a more complex waveform. JVP
contains a multi-tap delay which has six separately...

delay taps, to create even greater complexity. Using six taps, it is possible to
create very complex textures from the most common material. JVP also
allows you to use negative gain on the taps (the delayed signal has reversed
polarity) for even more sound shaping possibilities.
The illustrations below show the effect of using a multi-tap delay. For pur-
poses of clarity, the input signal is a simple pulse. In a musical application, a
copy of the instrumental or vocal...

General Controls
JVP contains four powerful DSP tools in one easy-to-use interface. It is con-
Þgured like a normal multi-effects processor with independent input and
output level controls and metering with the DSP tools connected together
in series. 
Input And Output Level Adjust
JVP has high resolution level meters calibrated to a resolution of 0.25 dB per
pixel with a total range of 45.5 dB. For stereo Þles, the level displayed is the
maximum of both channels. The...

Tool Bypass Buttons
Clicking on a Tool Bypass Button removes that tool from the signal path.
This is useful for isolating the effect the tool is having on the Þnished
sound. Clicking on all the Bypass buttons will leave only the input and out-
put level adjust sliders in the signal path.
