LOW SHELF: High Pass Filter control; adjusts the amount of low frequency rolloff
from 500 Hz down to 16Hz for the entire output of the RPQ160.
HIGH SHELF: Low Pass Filter control; adjusts the amount of high frequency rolloff
from 1 kHz up to 20 kHz for the entire output of the RPQ160.
NOTE: THERE IS NO BYPASS SWITCH FOR THE LOW OR HIGH SHELF
FILTERS - SIMPLY TURN THE LOW SHELF COMPLETELY COUNTERCLOCK-
WISE, AND THE HIGH SHELF COMPLETELY CLOCKWISE TO BYPASS THESE
CIRCUITS.
