Questions about equipment/backup

I get lots of questions about our equipment.  We use Two computers at every gig/event.  We use Serato Scratch Live on an IMAC Computer and PCVJ on HP Laptops=this is the best DJ software in our industry.  Every event has full backup as your Wedding/Party has every song you choose in virtual folders(Event,Cocktail,Dinner and Dance).  We put your music over 3 hard drives. With PCVJ software we are able to show Video, (MTV style).  Everyone loves to watch video, at the present time we have over 1,500=old school, 80's, 70's, Disco and Current Videos.   We only use JBL powered speakers.  JBL is famous for there concert speakers.  We us the JBL G-2 series.  These beauties are 400 watts per speaker and have independent sound on each speaker.  This great when you are at a venue and you want to jam over the dance floor==but want another area to have less volume.  With the powered speaker we are able to connect microphones directly into the speaker itself.  This is great for ceremonies or we are able to use  as a PA system for corporate events/Parties.  We only use Shure Microphones--Shure is considered one of the best microphones in the business.  We put body packs on ministers so you do not see Microphone stands during your ceremony.  We bring two wireless microphones to each event.  Your event is toooo important so we have two systems available at each event.
