The CDG-600RF is very similar to our already popular CDG-500RF with one major difference.... a built-in 250W power amplifier. Owners of the CDG-600RF simply have to connect speakers and microphones to have a full-fledged Vocal system. With an added cassette deck you can play and record your own demo tapes with ease. We have even included a Record Level Control for the cassette deck complete with an LED meter display. The CDG-600RF has Vocal features such as a 19-step Digital Key Controller, Digital Echo, Vocal Cancel and Partner features to remove guide vocals from multiplexed vocal tracks. There are 2 microphone inputs with individual volume controls, allowing singers to perform great sounding duos together! A third DJ microphone input is echo bypassed since most DJs prefer dry output for making announcements. Three audio and two video inputs allow DVD, VCD and LaserDisc players to be connected. VocoPro's CDG-600RF is a wise investment for anyone ready for quality Vocal entertainment!
