The 8-channel Fender Passport 500 PRO Portable PA system is Fender's most powerful portable PA system and offers the greatest clarity. But now Fender has added an input for recording your performances with CD-quality (WAV) straight to a USB flash drive. The Passport 500 also offers CD-quality WAV and MP3 playback, and a sub-out jack has been added for an external powered subwoofer.
