Make lessons and presentations more engaging by adding sound to your SMART Board interactive whiteboard. The audio system consists of a pair of 15-watt, stereo-amplified speakers with a two-port USB hub and a volume control button. The speakers can be mounted to the SMART Board interactive whiteboard or on the wall. As well, only one cable is needed to connect the speakers and the SMART Board interactive whiteboard to the computer, so there are fewer cables to manage. A DVD player or VCR can be connected to the speakers through an auxiliary input.
