The Shelf block includes one low-shelf and one high-shelf filter. The shelving filters are similar to bass and treble controls found on hi-fi audio gear. Use these filters for boost or cut effects over a broad range of low or high frequencies.
note: A bypassed filter’s magnitude/phase response and gain/frequency handle are hidden in the graph. By default the graph only displays the composite magnitude response (the total result of every filter in the block).

|Graphical representation of filters. Shows Magnitude vs. Frequency by default. Use the green/brown handles to adjust a filter's gain and frequency. Use View options to change graph content.|
|View options||Selecting Magnitude (selected by default) displays the filters' Magnitude on the graph. Selecting Phase (deselected by default) displays the filters' phase response on the graph. Selecting Composite (selected by default) displays gain/frequency handles for both filters on the graph. Selecting Individual (deselected by default) displays the individual contribution of the selected filter.|
|Frequency control||Displays the current frequency of the selected filter. Change the frequency by moving the slider or editing the frequency value in the edit box.|
|Gain control||Displays the current gain of the selected filter. Change the gain by moving the slider or editing the gain value in the edit box.|
|Bypass (above Table View)||Selecting this checkbox bypasses the selected filter, which effectively turns the filter into a wire.|
|Filter Table View||Displays the Frequency and Gain for each filter. To select a filter, click its row in the table. You can also bypass a filter by selecting its associated Bypass checkbox.|
|Bypass All||Selecting this checkbox bypasses both filters.|
