Galaxy Audio RM2 - Manual (Page 4)

The RM2 features two dedicated stereo outputs, allowing the
installed modules to be used as two separate devices in a single
rack space. Applications include having the RM2 equipped with
two different modules to service 2 different zones or rooms,
such as in a restaurant, school, church, etc. This configuration
also allows separate control of each module at the mixer. By
contrast, the stereo priority output allows program material from
both modules to appear at a single stereo output. This feature is
useful when continuous automatic playing of various media is
desired. One module is assigned as the priority unit As soon as
that particular unit produces a signal it will override the other
unit, and only it's signal will be present at the priority output
jacks. As soon as the priority device is no longer producing a
signal, the signal from the secondary unit will be fed to the
priority output jacks. Since the two devices feed a single stereo
output, the priority feature also helps conserve mixer input
channels. (NOTE: The priority feature only functions with the
RM-CDM as the priority device.)
