from Once you use it.Recently I was asked to select a simple sound system for a club my band plays in frequently. They asked me because the PA I have in the band is set up so we can perform at various sizes of venues and always get the sound we need for that venue.I purchased powered speakers for subs and mains FOH and also self powered monitors. This was for ease of use by multiple area bands who are talented but do not have their own sound system or soundman.When I first installed the system, I did the Eq by ear and let it go at that. The system sounded very good but seemed to lack the sound I had expected. I located a friend who's brother owned this Gold Line DP-30 RTA. I asked if we could rent or borrow it and he volunteered coming out and working with me to set the system up. I had used a low cost Peavey Eq prior with an auto set up feature and a calibrated mic and was not truly impressed with that gear so as I said I set this system up by ear.After the club closed, we started by setting up the calibrated mic began running pink noise through the system. Right away we noticed big gaping holes in the screens graphic of frequency responce. After some Eq tweaking, we found that individual speaker volume adjustments were needed, after performing some adjustment and continued Eq. tweaking the system really came to life. I found that with less volume cranked at each speaker location the spl increased with less demand on the mixer. How can this be? More reserve power for greater headroom, a much cleaner improved sound and the entire system is actually working easier.We went over the system a couple of times and continued fine tuning it for the room acoustics. I will never again mistake my ear for what the perfect sound.Having used this great package for a few hours I realized that there was basically no real learning curve. I can highly recommend this unit to any serious individual who desires the absolute best possible performance from any system so long as you have a good 20+ band Eq to make the necessary adjustments to the critical frequencies a specific room calls for. Whether you are reducing room resonance or increasing dead frequencies due to the rooms acoustical properties it will deliver everytime.
