The Dorrough 380-CE Vertical Loudness Meter -37dB 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 newsvan 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 43dB headroom displayed in 1dB steps. It is outfitted with XLR, DIP switch assignments, and mini DIN pin out, standard on most Dorrough units.

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.

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.

The 380CE, like all Dorrough loudness meters, simultaneously displays peak and average, in this model on an extended straight-line scale display calibrated to -37dB. The relative difference in dB between Peak and Average ballistics is derived from the integration time of the persistence scale.

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.
