We design and manufacture portable presentation systems for classrooms. Our flagship product, the AVRover SVS 200, is an all in one portable presentation system, which is rugged, secure and easy-rolling. It features a 2000 lumens XGA projector securely mounted on our universal patent-pending adjustable mount, speakers mounted on three sides, a mixer/amplifier, DVD/VCR combo, laptop cables, microphone input jack and audio line out jacks. Rack rails allow for additional components to be easily installed. There is also a smaller SVS 100. These systems will accommodate most late model projectors. All components are securely mounted in a well ventilated console with an ample work surface. Since there are no doors to unlock, the system is completely secure even while in use.
