I have owned my DJM-500 for over 4 years now, and it has lasted the test of time and the battering I have given it. Still perceived as the original ultimate professional dj/club mixer, it has remained as popular as ever. Its build quality is superb, but I believe its sound is not as good as other newer alternatives.
I am now looking to buy a new mixer - so will I buy another of these or a similar Pioneer product? I think not. I believe the advantages of the Allen & Heath Xone series outweigh Pioneer's mixers. Even so, I will still have a place in my heart for the DJM-500 as it was my very first mixer. I highly recommend this mixer to anybody who is starting out and want a mixer which is built like a brick and sounds good. I believe the main selling point for this mixer is its build quality and its built in effects unit, with effect such as flanger, phaser, and reverb.
The Pioneer DJM 500 is a wonderful, feature filled mixer with four channels, gains for high, mid and low frequency ranges and the obligatory cross fader. Where this mixer really comes into its own is with its effects unit which allows the DJ to add some originality and flair to his set. This effects unit includes effects such as flange, delay/echo, reverb etc. These allow the DJ a great deal of flexibility and allow him/her to give his/her set a unique sound. It includes twin beat counters for people who don't have great skill at assigning tempo to records. The mixer is solidly built, tried and tested and very reliable. In my opinion, it's not a patch on the DJ2000 by Roland, but it's probably my second choice.
