380-A

Dorrough

The Dorrough 380-A Vertical Loudness Meter +14dB is a professional analog loudness meter with a dual-channel vertical linear display, ideal for situations where many channels must be monitored in limited space, such as a mobile news van or crowded control room. The close side-by-side positioning of the two monitored channels facilitates critical comparisons. The unit shows simultaneous average and peak program information, with separate ballistics and lightning-fast response. It is equipped with a 40-LED bar graph with 14dB headroom displayed in 1dB steps. It is outfitted with XLR, DIP switch assignments, and mini DIN pin out, standard on most Dorrough units. Straight Line Display The 380 Series is functionally identical to the 40 series, except that the 380s have a straight-line scale designed for applications with limited vertical space. These easy-to-read meters are made to install easily in a custom console or in a rack with optional rack mounts. Dual Channel Meter These meters are ideal for situations where many channels must be monitored in limited space, such as a mobile news van or crowded control room. The close, side-by-side positioning of the two monitored channels facilitates critical comparisons.Peak and Average Metering The 380A, like all Dorrough loudness meters, simultaneously displays peak and average, in this model straight-line scale display calibrated to +14dB. The relative difference, in dB, between Peak and Average ballistics is derived from the integration time of the persistence scale.Right and Left Inputs for Stereo Mixing With one instrument, the operator can easily see the stereo mix and avoid classic in-phase/out-of-phase problems as well as center channel buildup that causes a mix to seem louder. This is especially important in preparing stereo program material for broadcast, while still being able to maintain monaural compatibility.
