The AT-LP1240-USBXP is a professional DJ turntable, designed for use in clubs, touring, mobile applications, and for home use as well. A switchable internal pre-amp gives it the ability to be used with a wide variety of A/V components. The USB output allows you to download or digitally convert your music. There is an S-shaped tonearm with adjustable tracking force and anti-skate adjustment. A speed indicator ensures that the record is rotating at the correct speed. The damped cast aluminum platter with stroboscopic markings and slip mat, the illuminated speed indicator, adjustable pitch control, and the dual start/stop buttons are very beneficial to DJs.
