Description

The Peak Program Meter uses fast DSPs to secure accurate level measurements of digital audio stereo signals. The digital AES-3 input signal is displayed on a familiar analog scale using 10 msec, 5 msec, or no time constant. A spot may be superimposed on the normal reading indicating true peak level.
