Audio apparatus demonstrating includes audio apparatus to be demonstrated. A display structure supports the audio apparatus and a digital computer controller. A CD-ROM is coupled to the audio apparatus and the digital computer controller with recorded sound signals for audible reproduction by the audio apparatus in response to selection signals furnished by the digital computer controller. A start demonstration switch is coupled to the digital computer controller. A proximity sensor provides a proximity signal to the digital computer controller when a person enters a predetermined zone around the apparatus to cause the digital computer controller to select a change in the record signal reproduced by the audio system from a first signal to a second signal which second signal encourages the person within the zone to actuated the start demonstration switch and initiate a demonstration of the audio apparatus including audibly reproducing sound signals recorded on the CD-ROM.
