Marantz was showing off their new PSD300, an excellent portable CD recorder designed for the performing arts industry. The PSD300 is unique in that it is a CD-RW recording system with a separate CD-R/W player with realtime manipulation controls. It’s a fantastic rehearsal and practice tool. Did you ever want to change your favorite song by a half step? Or slow it down a bit without changing key? The PSD-300 can do it, as well as allow you to create A-B practice loops or tone down your lead vocals. Other features include a built-in microphone and speaker, stereo XLR & 1/4″ mic/line inputs, programmable mic/line EQ and filtering, and automatic record level control.
