Shelving filters
Pulsar Massive’s high and low-shelf filters are also unusual when compared to those present in
modern equalizers. With increasing bandwidth, a shelf will introduce a complementary bell filter,
at the other side of the corner frequency – a scoop before a boosted shelf, or a bump before an
attenuated shelf.
This type of filter allows, for example, in the case of a high-shelf, to add power in the very high
end of the spectrum (frequencies above 8-10 kHz), while keeping harsh frequencies (between 2
kHz and 4 kHz) unchanged.

Note: This setting can be misleading. For example, when the Bandwidth parameter is set to
maximum and you try to boost the high frequencies above 8.2 kHz, the shelf filter will also
attenuate the frequency area around 8 kHz due to the added bell filter in the opposite direction.
For this reason, you will often be surprised at your own frequency choices when using the
Massive's shelf filters! The best frequency choices will often be higher than you would expect for
low-shelves, and lower for high-shelves. The Pulsar display rack provides graphical feedback on
the proposed EQ, and allows the user to better understand the filtering done by the plugin.
