The 20-A Analog Loudness Meter is a horizontal, single rack space version of the popular Dorrough 40 Series. Designed with professional broadcast production and modern digital studio recording in mind, the Dorrough meter displays two separate ballistics simultaneously. This allows the operator to quickly see relationship between the peak and the average of a stereo audio signal on a single meter, and to make informed adjustments as necessary.
With the addition of the 20D or 20S mounting assembly, you can rack up one or two 20-A meters in a single rack space.
Straight Line Meter
The compact 20-A features the accuracy of the 40 series in a single rack space, straight line (not arched meter) version.
