Any time and any place you need big sound with great clarity and convenience, there's a Passport® PRO system by Fender® that's right for you. PRO models are the latest step in the ongoing evolution of Passport into the very finest in portable PA solutions; keeping the best of previous Passport generations and adding new features and improved functionality so that Passport systems are ideal for whatever your application may be - education, sporting and worship events; meetings, seminars and presentations; gigs at parties, small clubs and coffee houses. The four-channel Passport 150 PRO system boasts lighter weight (a full three pounds lighter than the earlier Passport 150 system), two stereo channels (up from one on the earlier Passport 150 system) and improved speaker voicing.
