Center frequencies range from 20 Hz to 20 KHz. The on-
board frequency jumper divides the frequency range into three
bands: 20 Hz to 200 Hz, 200 Hz to 2 KHz, and 2 KHz to 20 KHz.
Simply place the jumper in one of the three positions which cor-
responds with the frequency to be adjusted. The specific fre-
quency is then selected via the "frequency" potentiometer

quency di vi ded by t he bandw i dt h. A s "Q " goes up, bandwi dt h
decreases. The P500's "Q" adjustment ranges from a narrow
bandwidth of 10 to a very broad bandwidth of 1.
Boost / Cut on the P500 is +/–18 dB. The rotary poten-

RTA and adjust pink noise SPL to 85 – 90 dB.
Turn the boost/cut control to +18 dB (full clockwise
rotation). This will show the present center frequen-
cy and "Q" settings on the analyzer.
Rotate frequency control to the frequency you wish to
adjust.
Adjust "Q" setting to match the width of the dip or
peak you are addressing.
Finally, adjust the gain control to achieve the desired
response curve.
