Shelving filters are used primarily as “tone controls,” 

cutting or boosting whole regions of the spectrum. (You 

can think of them as fancy versions of the traditional “Bass” 

and “Treble” controls you’d find on home stereos or boom 

boxes.) A high shelf filter, for instance, acts by raising 

or lowering the part of the spectrum above the cut-off 

frequency.
The graphs below show the response of the high shelf 

and low shelf filters at +12 dB gain. Notice that the slope 

of the roll-off is 6 dB per octave. The TA-1VP’s shelf filters 

provide a slope control that let’s you vary the filter’s slope 

between 2 dB and 12 dB per octave.

The peaking filter is the traditional fully parametric EQ. It 

can be used to subtly accentuate or attenuate a frequency 

or for much more radical effects.
In the TA-1VP, the peaking filter works over a range of 

20 Hz to 20 kHz and can boost or cut the signal at the 

selected frequency by ± 18 dB. Additionally, you can vary 

the bandwidth from 0.1 to 4.0 octaves.
The graphs below show the effect of changing the 

bandwidth control of the peaking filter.

Band pass and notch filters can be thought of as extreme 

examples of the peaking filter.
The Band Pass filter sharply attenuates all frequencies 

except for a band centered around the cutoff frequency. 

The width of the pass band is set by the bandwidth or “Q” 

control. The band pass filter is typically used to isolate a 

particular frequency range in a track or mix.
The Notch Filter passes all frequencies except for a band 

centered around the cutoff frequency, which is sharply 

attenuated. The width of the notch is also set by the “Q” 

control. The notch filter is used to eliminate unwanted 

sounds appearing at a specific frequency in a track or mix.
