The Express Box MKII 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 MKII is worthy of investigation.

Inputs
Two 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 two mic inputs. The two talkback circuits have individual outputs and are common for both commentators.

Monitoring
There are four 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.

Virgil OB Overview

It is possible to set the Express MKII to operate as a simple two language interpreter’s unit. If set to interpreter mode then A and B Mic On buttons latch and toggle on/off. TB1 buttons also latch and toggle on/off. The MIC A & B buttons interact with their own channel’s TB1 button, whereby a channel’s Mic On and TB1 (on) button cannot both be on at the same time and pressing one while the other is active will cause them to toggle. The above means that Mix Out would be used for language one and TB1 out would be used for language two. TB2 button still works as an off air talkback channel and pressing it will automatically turn off either Mic ON or TB1 (on) if they were on, on the channel that TB2 has been operated on.
