Dorrough Electronics designs and manufactures precision audio and video monitoring devices. For the past 20 years, Dorrough has pioneered new technologies in audio signal processing, and monitoring for the broadcast, motion picture, and recording industries. Although having developed and marketed the first Discriminate Audio Processor (DAP) in 1973 (shown at the right), the company is best known for its award winning Audio Loudness Monitors in widespread use throughout the motion picture, recording, and broadcast industries worldwide.
  The Model 40 Audio Loudness Meter with its classic "eyebrow" scale comprised of 40 LEDs, revolutionized audio monitoring by simultaneously showing both the traditional average program level, and the peaks on a single scale.
