The levels of all six channels as well as the phase correlation between all combinations of two channels are represented, so that defined statements are possible for the mono compatibility of a stereo and a Surround signal, in addition, for the Stereo compatibility of a Dolby Prologic signal or a 5.1-Signals in the Downmix.

Also the level-moderate simulation of the procedures with the Downmix on a stereo or a Dolby Prologic signal belongs to the function range of this software.The correlation degree is a measure for the mono compatibility. This value is measured and indicated on an LED chain. As soon as this deflects into the red range, is somewhat not correct. Also on a two-jet oscilloscope in the XY enterprise one can read off the correlation degree with something exercise. A mono signal results in senkrechten a line, a Stereosignal with correct phase a circular picture, and with to strong opposite phase a horizontal arranged egg develops.

Since this representation is quite comfortable, there is also so-called Stereo-scope, which is particularly for the connection in the studio appropriate in contrast to the normal oscilloscope. However reading off requires something exercise, why the PAS Surround meter another way goes: All ten possible pairs of channels are represented in an announcement, which should lie within the range between 0 and +1. If it deflects into the range between 0 and -1, no mono compatibility is given with the pair of channels concerned.
