The GS-CU001B Mk II is a highly versatile commentary unit. It was designed after close consultation with end users and the result is a stand alone unit which offers a wide range of facilities, and it is equally at home on the terraces, as it is in a studio.

There are two main commentator monitoring sections, each with two separate 6.35mm A or B gauge jack sockets for headphones. In this way, the centre position B commentator can choose to share the monitoring of commentator A or C. There are 5 common external sources available for monitoring, plus an additional control which is the sum of the other 2 commentators/inputs. Each of the 6 pots has variable level control and left/both/right switching allowing commentator A and C to achieve their desired mix and balance levels. The sidetone control is located on the rear panel for commentator A and C to adjust the level of their own voice. There is a 7 segment LED PPM meter.
