glensound express box mk11 1

The Glensound Express Box MK11 was designed to provide a quick and easy solution when it is necessary to provide interfacing for two commentators, with simple facilities. This high quality commentary unit is ideal for those looking for cost effective solutions without paying for unwanted features; the Express Box is worthy of investigation.

Two front panel mic inputs with selectable 48v phantom power.

Each mic input has its own individual output. There is also a mixed output of the two mic inputs. The two talkback circuits have individual outputs and are common for both commentators.

There are four inputs for external sources, and one sidetone pot of their own voice. These are available independently to each commentator on individual pots, so each can adjust the inputs for their own preference of mix level. There are two 6.35mm headphone sockets – 1 for each commentator. A 7 segment LED PPM meter displays level.
