Samson Expedition 310W.

The Samson Expedition XP310w rechargeable portable sound system answers the call of those who need great-sounding mobile audio. With 300 watts of power and 12 hours of battery life, a top-mounted 4-channel mixer, and Bluetooth, the XP310w delivers excellent sound to musicians, DJs, and others who enjoy a variety of outdoor events. A frequency-agile wireless microphone provides wireless performance. The XP310w operates continuously for up to 12 hours 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-inch woofer and 1-inch tweeter, all housed in a rugged polypropylene enclosure with a 27.5-pound steel grille.

With a locking telescoping handle and smooth-running wheels, the XP310w is easier than ever to transport. A 1 3/8" speaker stand socket allows the XP310w to be mounted with any standard speaker stand. Equipped with a top-mounted 4-channel mixer with XLR, 1/4", and 1/8" inputs for connecting microphones and line-level devices, the XP310w makes setup quick and easy. The speaker can also stream music wirelessly from any Bluetooth device. A variable reverb control adds depth, and a voice-over ducker automatically lowers the music when you speak or sing into a microphone (XLR or wireless inputs).

Additionally, a master 2-band EQ is provided to customize the XP310w's sound characteristics, as well as a line output to daisy-chain additional speakers. The XP310w is perfect for vocal and voice applications with multiple performers and can manage up to three wireless systems simultaneously. The XP310w comes with a single frequency-agile Concert 88a handheld UHF radio system that provides up to 300 minutes of operation. An additional wireless receiver slot is included to add a second Concert 88a Series wireless system (sold separately), while you can also integrate an XPD Series digital USB radio system (sold separately) via the wireless USB port.
