This configuration is well known for its wide horizontal, narrow vertical acoustic pattern that permits outstanding audience coverage with minimal microphone feedback problems. The 1207C's 75-watt capability and wide frequency response provides intense reinforce- ment of the human voice and musical instruments covering the same range. The enclosure is covered with attractive, rugged vinyl and has heavy-duty edge bumpers. A retractable carrying handle adds to its portability.
