Traveler 8 wireless speakers features 8-inch woofer, 1-inch horn, 50 watts amplifier and can be configured in a variety of ways to meet your specific needs. Standard traveler includes 2 inputs (XLR/1/4-inch combo with its own volume control and a dual RCA), 2 band equalizer and master volume. Audio outputs include a dual RCA line out and 1/4-inch speaker output to power an additional speaker. The universal power supply/battery charger allows the traveler to be used anywhere in the world. The Traveler will operate for an unlimited time on AC power and for about 6 hours on just battery power. A full recharge of the batteries takes about 4 hours. The traveler may be operated while recharging the batteries without affecting the charge time. If a power failure occurs when operating on AC, the traveler will seamlessly switch over to battery power. The traveler has a unique plug in modular design, which allows optional function modules to be easily added or removed. Optional modules include wireless mic receivers (with handheld, headset and lapel options), a CD/MP3 player and the choice of an echo/delay unit or an audio link module, which wirelessly transmits the entire audio mix from one traveler to any number of satellite travelers. Since all the modules are internally wired no external patching is necessary. The durable ABS enclosure features a convenient carry handle and a provision for standard pole mounting. The Traveler is designed for people who need a portable, lightweight, all in one PA system that allows for a quick and uncomplicated setup.
