Low Shelving Filter

Purpose

The Low Shelving Filter behaves like the High Shelving Filter except it allows the low frequency components of the spectrum to be boosted or cut.

Controls

Bypass

The Bypass button bypasses the device.

Frequency

Adjusts the transition frequency of the shelving filter.

Level

This adjusts the level of the low frequency shelf relative to the un-shelved portion of the frequency spectrum.

Note: It is possible to overload the filter if Level is set above +0dB. Such an overload will be indicated by the Overload Indicator.

Overload

Indicates clipping in the filter. Clipping is only possible if the Level control is set above +0dB.

Graphical Frequency Response

Displays the frequency response of the filter. See the EQ Curve Graphics Display documentation for a complete description.

Frequency Response

The response of the Low Shelf filter is shown for a Level control setting of +6dB (red) and -6dB (blue) and a Frequency control setting of 1,000Hz.
