APPLICATIONS
A. Using the 410 in conjunction with a real time analyzer
(such as DOD’s RTA Series II), a calibrated microphone, and
pink noise generator, the audio system may be tuned to make
the overall audio spectrum response of the sound system and
the room environment flatter in frequency response.
B. Greater gain-before-feedback characteristics may be
achieved by turning up the sound system to the feedback point
and attenuating the oscillating (ringing) frequency using the
notch filters. Turn the system up to feedback again and attenu-
