Effects(All images from Musiciansfriend.com) Here is a multi-effects primarily used for reverbs of inputs, two different effects could be used. This is a crossover/enchancer. It is designed to take the bass frequency and add another octive to the bass frequency, great for dance club work. This is a stereo 30 band equalizer, it helps with eliminating frequencies that could cause feedback, also helps with tuning a speaker system to sound its best. This is a crossover, it is needed for subwoofers to amplify bass frequencies. You could think of it as a separator. So many effects, and so little time :-P check out musician's friend to see a list of effets used for live sound. < Introduction | Mics | Mixers | Effects | Poweramps | Speakers | Works Cited > |
