3. With this in mind we would like to offer some tips to get you started in the right direction Tip 1 Always listen to the PA system with the graphic EQ in bypass before you start fiddling with the sliders because many frequency response problems are actually something else entirely If something sounds wrong check your entire PA system for proper hookup and performance BEFORE you start working with the equalizer For example O Make sure that all the speakers are 20 25 31 5 40 50 63 80 100 125 160 200 250 315 400 500 630 800 1K 1 25K 1 6K 2K 2 5K 3 15K 4K 5K 6 3K 8K 10K 12 5K 16K 20K working properly Check each driver within an enclosure separately Large sound systems may have many identical drivers in an array making it hard to pinpoint blown or out of phase drivers by ear Adjust your overall system gain structure so that all of the components in the signal path are operating at nominal levels Check your cabling The vast majority of sound system problems are related to cables Intermittent connections polarity reverses bad grounds shorts etc are all examples of problems that can manifest themselves as frequency response problems For instance if the cable feeding your stage left subwoofer array is polarity reversed causing the left subwoofer array to be out of phase with the right subwoofer array you will percieve this as a lack of adequate low

7. because out of the sea of graphic eqs that you might have purchased the 533E is one of the only affordable equalizers that offer truly professional performance How did we do this First because our design team believes that no one should have to settle for good enough they threw out the conven tional design ideas and started from scratch The result a highly advanced filter topology that delivers extremely low distortion and noise even at very high signal levels Second our state of the art facility gives us the ability to build quickly consistently and in high volume allowing us to keep our prices low In addition the 533E makes extensive use of surface mount components This allows us to cram more circuitry onto a smaller circuit board further reducing costs In fact the 533E is a purist s dream audio phile sound quality uncluttered control surface and rugged reliability in one package They offer thirty one filter bands per channel on ISO 1 3rd octave centers Through the use of a global range switch each band delivers either 6dB or 12dB of cut or boost The grounded center detent position on each band serves as an on off switch that completely removes that band from the audio signal path In addition they sport 12dB per octave High Cut and Low Cut filters Each has a sweepable cutoff frequency and a control range that extends well into the sub ultrasonic Of course the controls and features are secon
