This sound-activated clock will grab the attention of your customers and make your promotional message virtually impossible to ignore. Its rainbow-colored electrical pulsations will flash in sync with music or the sound of your own voice. The intensity of the effect mirrors the loudness of the sound. The plasma feature can also be set to run continuously or turned off to save power. The analog clock, with hour, minute, and sweep second hand, features a high quality quartz movement and your logo printed on the clock face cover. Made of sturdy plastic, the clock has a fold-out metal easel stand for desktop use, or you can hang it on the wall with the recessed hanging notches on the back. The clock operates on 1 AA battery (not included). The plasma display can be powered by 4 AA batteries (not included), or an included AC adapter. Gift boxed.
