Applications Bar Yeah, you know. A bar...or “club”. This example assumes a small bar with live music, but not a full blown stage with lights and huge flying loudspeaker arrays, etc. Basically, this is the type of bar where you go to get some food, have some adult beverages and kick back.

The Master mixer feeds the power amplifiers and the logging recorder. Using the Aux output for the logging recorder provides a separate volume control, and channel assignment.
