Description
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.
The MK II Version
The MkII version now adds the following as standard features:
VERSION 1: This version has electronically balanced audio input & output circuits.
VERSION 3: This version has transformer balanced inputs & outputs with high quality Llundhall transformers on the individual mic outputs.
Inputs
3 front panel inputs are mic/line switchable with selectable 48V phantom power. The front panel also has a small gain adjustment pot. Mic on/off switches can be selected in on/off mode or in cough mode. There is a global low frequency cut that can be selected on or off, and a preset compressor/limiter per input.
Outputs/Talkback
Each input has a direct discrete output on the rear panel along with a mixed output of all of the inputs, all on XLR. The mixed output is also available on an un-balanced 3.5mm jack socket as a local record. The direct output levels can be set in 3 positions:
There are 3 common talkback circuits with individual buttons on the two main commentators’ sections (Position B's input cannot be switched to a talkback output). The operation of the talkback buttons features Config+ for configuring in different modes.
Monitoring
There are 2 main commentator monitoring sections, each with 2 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.
Power
There is an internal switch mode power supply 100-250 VAC, with external power via a 4 pin XLR 9-18 VDC.
Flight Case
By popular demand a hard wearing strong polypropylene flight case is now available for all of the GS-CU001 range. It features long life hinges, easy to use catches and being made out of hardwearing polypropylene plastic, it will last for years. Internally the case is lined with cut out medium density foam. The multipurpose cut outs can be adapted to accept any of the different size GS-CU001 units. A second small cut out is included suitable for two HMD25 headsets & mains cable.
Modifications
The GS-CU001 is a complete and versatile base system, and Glensound's most popular commentary unit. It is therefore a perfect starting point for custom requirements. This has resulted in many custom modified units, some listed above, and some not. Some examples for custom modifications:
