This BOSE S1 Pro+ wireless PA system comes with two instrument transmitters and an S1 Pro backpack included. 

Bose S1 Pro+ Wireless PA System

The next time you perform, bring the versatile, portable, powerful Bose S1 Pro+ wireless PA system. It lets you add any vibe anywhere you play, with a wireless design that’s more lightweight and powerful than the original. Connect your equipment with an integrated 3-channel mixer and access controls like independent EQ, reverb and ToneMatch presets with intuitive OLED displays. Or, get it all on your phone through the Bose Music app.

Simplify your setup further with the included wireless RF transmitters. They connect effortlessly to the system’s integrated wireless RF receivers, so you can leave the cables in your case and get to playing faster.

S1 Pro+ Backpack

A rechargeable lithium-ion battery provides the Bose S1 Pro+ up to 11 hours of play time per charge, while the system itself weighs just 14.4 lb. Place it vertically, tilted back, horizontally or on a speaker stand (it’s compatible with standard 35 mm mounts). Auto EQ senses the orientation and adjusts the speaker’s performance. Between gigs, stream music over Bluetooth at your next backyard gathering or karaoke party.
