Sound Reinforcement Applications

SR Series EQ’s 5

APPLICATIONS

DOD graphic equalizers can be used wherever modification of the frequency contour of a sound or sound system is needed. A graphic equalizer offers a solution to many common sound problems, both large and small. Also, creative experimentation on the part of the user can produce some nice results.

By routing the signal from the mixer to the SR Equalizer, and then to the main power amplifiers (or crossover), the overall frequency of the mix can be altered to do a number of things.

A. Using a real time audio spectrum analyzer (such as DOD's SR Series RTA), a calibrated microphone, and a pink noise generator, the audio system can be tuned to make the overall audio spectrum response of the sound system and the room environment equal in frequency response.

B.Greater gain-before-feedback characteristics can be achieved by turning up the sound system to the feedback point and attenuating the oscillating (ringing) frequency. 1/3rd octave resolution is best for this application. Turn the system up to feedback again and attenuate the second oscillating frequency. Repeat the process again for the third oscillating frequency.

C.Protection of amplifiers and speakers can be accomplished using the LOW CUT feature of the equalizer. Wind noise or sub sonic frequencies can cause damage to the amps and/or speakers. However, by rolling off the extreme low frequencies, a measure of protection is added to the system without severely affecting the overall sound quality.

D.In noisy environments, the audio signal can be tailored for better intelligibil- ity and penetration. This is particularly useful for paging systems.

E.Creative use of the equalizer allows shaping of the signal for a more pleasing sound or for special effects. The only limits are those of taste and imagination.
