The Galaxy Audio GPS-8 full range personal monitor PA system packs huge sound while remaining compact and versatile. The GPS-8 is a powered, 200-watt, two-way, compact PA speaker with a unique asymmetrical shape which allows for wedge placement or pole mounting. Lack of low end response is a major drawback of most compact PA speakers. The Galaxy Audio GPS-8 addresses this need with a push button Bass Boost feature which enhances low end. The GPS-8 has a mic/line switch, as well as a variable gain control, giving it the capability of accepting most any input level. The handy XLR/1/4" combo input jack accepts balanced and unbalanced signals. There is an LED to indicate when switched into mic level position. You can tell at a glance your input status via the green LED for signal input and the red LED indicating the on board limiter is functioning and that the level should be reduced.
