The Samson Expedition XP310W K Rechargeable Portable PA answers the call of those who need great-sounding mobile audio. With 300 watts of power, 12 hours of battery life, a top-mounted 4-channel mixer and Bluetooth, the XP310w delivers huge sound to musicians, DJs or those enjoying a variety of outdoor events. It also includes a K-band frequency-agile wireless microphone for cord-free performance. The XP310w operates for up to 12 hours continuously via its built-in rechargeable lithium ion battery. Its lightweight Class D amplifier delivers 300 watts of power to a 2-way speaker system with a 10" woofer and 1" tweeter. This is all housed in a rugged polypropylene enclosure with a steel grille that weighs 27.5 pounds. And with a locking telescopic handle and smooth rolling wheels, transporting the XP310 is as easy as it gets. Plus, a 1 3/8" speaker stand receptacle allows the XP310w to be mounted using any standard speaker stand. Equipped with a top-mounted 4-channel mixer that includes XLR, 1/4" and 1/8" inputs for connecting microphones and line level devices, the XP310w makes for quick and easy setup. The speaker can also stream music wirelessly from any Bluetooth device. A variable reverb control adds depth, and a voiceover ducker automatically lowers the music when speaking or singing into a microphone (XLR or wireless inputs). In addition, a master 2-band EQ is provided to adjust the tonal characteristics of the XP310w, as is a line output to daisy-chain additional speakers.
