Audio Visual Equipment

Audiotronics, a North Hollywood-based designer of audio-visual equipment, reported a narrowed net loss of $179,000, or 15 cents a share, for its third quarter, ended March 31. During the same quarter last year, the company posted a loss of $878,000, or 74 cents a share. Charles A. Musson, president and chief executive, said Audiotronics' loss shrank because of improved results from an unprofitable video monitor business.
