Before I get into my new toy, let me explain the beauty of a controller. Back in the day, the dj had to use a mixer and hook it up to two turntables that were connected with multiple rca cables. Then the mixer would connect with the speakers and then the gig had music. Usually it would take about 45 minutes to set up solo. A controller contains a mixer and turntables as one. So the use of rca cables is unnecessary and set up takes half the time. Gotta love technology!
My controller of choice is the DDJ SX2, which is the industry standard for mobile and nightclub djs. This is a four-channel controller. I take this guy everywhere. As his backup I would take the original Pioneer controller DDJ-s1. Since I never needed a back up, I would never use my original controller. I decided to get a newer back up in the DDJ-sr2, which is a two-channel controller. This looks like the little brother of what I use now.
The ddj-sr2 is smaller and lighter than his bigger brother. With this controller, it can be powered by usb or with a powered plug, which could be a lifesaver incase one runs out of outlets. If a venue has a professional sound system, this controller can be connected to it with ease.
It can also be used for a wedding in case multiple set ups have to be ready at the same time for the ceremony and the reception. If both events happen in the same venue, the guests can leave the reception immediately and be greeted by music when they enter the next room right away.
