It also includes a 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.FeaturesAll-in-one portable PA system that weighs 27.5lbInternal rechargeable lithium ion battery for up to 12 hours of continuous useBluetooth connectivity to connect wireless music sourcesIncludes Concert 88a Handheld Frequency-agile UHF Wireless System (300' operating range)Extra wireless receiver slot for adding an additional Concert 88a Series wireless system (sold separately)2-way speaker enclosure with 10" woofer and 1" tweeterClass D amplifier produces 300 watts of Peak powerTop-mounted 4-channel mixer with 2-band (Bass and Treble) EQIndependent volume controls on each channelXLR-1/4" combo selectable mic/line input for microphones and line level devices1/8" (3.5mm) input for stereo line level devices (MP3 players, keyboards, etc.)Variable reverb control for mic/wireless inputsVoiceover control with priority duckingLine output to daisy-chain multiple systems togetherUSB wireless port for use with Samson XPD Series USB Digital Wireless Systems (sold separately)Battery level, Charging and Power LED indicatorsRugged polypropylene enclosure with steel grilleLocking telescopic handle and smooth rolling wheels for easy transport1 3/8" speaker stand mountTwo integrated microphone mounts for wireless mic storageSpecificationsOutput Power: 300 watts PeakFrequency Response: 50Hz–18kHz (-3dB)Speakers: 10" woofer, 1" tweeterInputs: XLR-1/4" combo Mic/Line, 1/8" Aux,USB wirelessOutputs: 1/4" LineLevel Controls : Master, Channels 1–3, BluetoothTone Control: Master Bass and Treble EQDynamics Control: Reverb, Voiceover (switch)Bluetooth: Bluetooth 4.0, A2DPBattery Life: Up to 12 hours by built-in Li-ionBattery Charging: 4-6 hoursConstruction : Polypropylene, steel grille, telescopic handle, smooth rolling wheelsAccessories: Extra UHF slot coverWireless System: 1x Samson Concert 88a Handheld UHFWireless Working Range: 100' (30m) line-of-sightWireless Working Frequency: Available bands include D, K and GProduct Dimensions: 22" (560mm) x 12.25" (310mm) x 12.25" (310mm)Product Weight: 27.5lb (12.5kg) Samson Expedition XP310w 10 Rechargeable Portable PA with Wireless Handheld Microphone - K Band.
