Deliver brilliant sales presentations with Anchor Audio's Beacon Sound System. With 150 watts of AC power, this impressive PA system reaches crowds up to 5,000 people. Three woofers in the base of the unit and a line array tower with eight mid-range speakers combine to provide full-range sound to your entire audience. A selection of inputs and outputs let you hook up microphones, laptops, additional sound systems and more.

The built-in MP3 player accepts SD cards, USB flash drives or 3.5 millimeter inputs. Use the AC power supply or two rechargeable batteries to operate your public address system. A nylon storage bag keeps your system safe from wear and tear. Move it to your next location using the handy travel dolly with wheels and a retractable handle. This system includes two wireless microphones and two wireless receivers with 16 user-selectable channels each.
