Description
The Express Box MKII was designed to provide a quick and easy solution when it is necessary to provide interfacing for 2 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 MKII is worthy of investigation.
Inputs
2 front panel mic inputs with selectable 48V phantom power.
Outputs/Talkback
Each mic input has its own individual output. There is also a mixed output of the 2 mic inputs. The 2 talkback circuits have individual outputs and are common for both commentators.
Monitoring
There are 4 inputs for external sources, one sidetone pot of their own voice and one other commentator pot for listening to the co-commentator. 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.
