* The Expedition XP150 offers a PA solution that combines powerful stereo sound with portability and simplicity. With its clever design, the XP150 packs up into a single unit that weighs only 24 pounds. Perfect for schools, conferences and presentations, as well as musicians and singer-songwriters, the XP150 is the ultimate in portable sound. A removable 5-channel mixer powers the XP150 with a 150-watt (2 x 75) Class D amplifier. The mixer features three Mic/Line channels with XLR and 1/4-" inputs, allowing you to connect microphones or line signals. It also includes one stereo 1/4-" and 3.5mm input channel for connecting external devices like MP3 players, keyboards and more. There’s also a built-in digital effects processor to add Digital Reverb to your voice or instrument. Each channel features 2-band (bass and treble) controls.
