DJ mixers are one of the latest and most popular instruments. These turntables require exceptional skill with knowledge of music, tempo and technology. Turntables were invented in the 1970s as a way of scratching and pulling on albums to create unique, dynamic sounds. Today, turntables are still very popular in clubs and at parties. Typical turntables start at about 200 dollars, but can range up to a total price of 100,000 dollars. The more simple devices are run using a direct drive while the higher priced turntables use advanced rubber belt drive technology with electronic attachments. It all depends on what the DJ wants to accomplish with his instrument, and how experienced he or she is in the art. Some of the most popular devices are the Linn Sondek LP 12, and the Roksan Xerxes. All in all, these instruments are quickly becoming a must for every party, and every club.
