Everything You Need, Even Good Sound. Expedition Express is the total solution to professional sound, made portable. It gives you everything you need to make a professional presentation anywhere you can roll it. Expedition Express is a great solution for performers on the move. Bands, mobile DJ's, schools, houses of worship, corporate A/V and institutional applications-anywhere portable, high quality sound is required.Unlike most portable PA systems, the Expedition Express is designed to sound great. Not just for public speaking either-but for live and recorded music, too. The system is comprised of a pair of rugged, acoustically balanced two-way loudspeakers, a 4-channel mixer with DSP, a powerful 250 Watt amplifier and all the accessories you need. What's more, the system interlocks, and packs up into a single rolling unit so it's easy to transport. We've thought of everything: Expedition Express includes a professional dynamic microphone, mic clip, mic cable, extension speaker cable and protective ballistic nylon cases. Compact and Powerful: The Expedition Express combines a powered speaker with built-in amplification and controls, and a light-weight second speaker or "Slave". When set up for performance, the two cabinets are connected by a single cable. When they are packed of for the road, the lightweight passive speaker cabinet locks into the top of the amplified speaker cabinet with a unique auto-locate mechanism. Each loudspeaker is housed in a lightweight, yet heavy-duty, molded resin cabinet with extensive internal bracing to give it rigidity, low resonance and the maximum possible volume. Pro Quality Electronics: The Expedition Express's integrated amplifier is perfectly matched to the drivers for surprisingly high efficiency. The sound is clear and hard-hitting. Built-in digital signal processing (DSP) adds dramatic pro-quality effects like reverb and echo at the flip of a switch. Selecting from six preset effects makes getting great sound easy and fast. Like Samson's Expedition Pro enclosures, the Express features custom designed high and low frequency drivers. The High Frequency section employs an elliptical wave-guide horn that offers extra wide dispersion for maximum coverage. Samson's engineering team set out to design the ultimate in portability, with professionally superior sound for all kinds of applications.With molded-in handle and wheels, you can roll the cabinet anywhere you want. This makes Expedition Express ideal for boardrooms,
