I'm confused....
if you are talking about DJing, then it CAN be done with no processing. A simple BASS, MID, HIGH adjusment can be enough...
are you confusing DJing with live sound.? Any Sound System will have similar basic audio challenges from one venue to another. No one system can automatically adjust to these challenges by itself. If you want to put on a song and have the speaker system reproduce it, this is what would happen. If you want to have the best reproduction possible, then you may have to tweak it by using processors.
you know as well as anyone that they are APPLES and ORANGES
and no one could amplify an entire live band with powered DJ speakers and no processing
don't try to answer one argument by using the other as your example
DJ systems and live sound systems both operate on the same Audio Principles. For example, comb filtering can occur no matter what speakers are being used if the placement is incorrect. The difference between a regular DJ System and a Live Sound System is basically the size. For example, take two cars, one with a four cylinder engine and the other with an 8 cylinder..they can both do the same thing namely take you from Point A to Point B. However, I am sure you will agree that one is superior to the other as far as power. If one is happy with the teeny high pitched sounds that are emitted by regular DJ speakers then thats fine. I prefer to have a more full bodied sound that you can only get from specialized speakers and processing equipment
the same could be said about... CD's or cassettes When Vinyl was King and hardware was the only option, you had to buy your own. Now music and software can be duplicated and copied illegally.
I started with cassettes. it made it easier for me to get into the biz when everyone else was using LP's
and when CD's arrived on the scene
I'm sure it allowed many new DJ's to get into the business
(perhaps many who are well respected and ON this very site...)
yeah, the kids these days have it easier than we did.
and we had it easier than the guys before us...
