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. This Pro 500 is also 9 pounds lighter than the previous version with reduced, more portable dimensions. The redesigned speaker system features two molded plastic cabinets with a 10" woofer and a 1.2" horn-loaded tweeter in each to deliver better definition than before. When not in use, the speaker clips to the mixer for a convenient, one-piece portable system.
