stereo lo-cut filter

This filter reduces or eliminates unwanted low frequencies to clean out the mud that often accompanies reverbs or synths. The cut-off frequency of the filter is 150 Hz and the slope is -18dB per octave. This type of filter is also referred to as a Hi-pass filter (HPF). It allows the hi-frequencies to pass, but stops the lo-frequencies.

Reverbs can have a	+
sizable amount of

low frequency rumble that is best removed with a low cut filter.

Some synth patches have so much low frequency energy that they lose definition and need high pass filtering.

Engaging the Lo-Cut filter can eliminate these power- stealing low frequencies.
