The Glensound Talent Box is the next generation of single unit commentary systems. Digital in both control and internal audio circuits with extended positions. A web page allows an engineer to remotely control incoming audio levels - a first for a single unit commentary box. Talent Boxes can also link for multiple commentator systems.

Inputs
3 front panel inputs on XLR are mic/line switchable. Input B has an additional parallel input on a 3.5mm jack socket. There is an adjustable gain control and a phantom power switch to add 12V or 48V phantom power (this can be locked on/off in the configuration menu). The mic on/off button can also be configured as a cough button. The inputs have a configurable compressor/limiter.

Outputs/Talkback
There are 3 direct outputs of the mic/line inputs. These are at adjustable level with optional limiter. There are 2 configurable master outputs, that are a mix of the 3 inputs. An un-balanced 3.5mm jack socket is available as a local record out. There are 3 common talkback outputs with Config+ push buttons, which are level adjustable to match an external talkback system. A digital line ident is provided and is controllable via a rear panel switch, which gives a looped message and 1.6kHz tone to the outputs.

Monitoring
With 2 fully featured commentators' positions A and C, the centre B position has no access to the talkback circuits (unless using external remote) and can choose to share monitoring with commentator A or B. The 3 headphone connections are via front panel 6.35mm jack sockets. There are five variable pots for external source level mixing, one pot for the commentators sidetone, and 1 for monitoring the other 2 inputs. Each of these inputs (ex sidetone) has soft headphone switching between left/both/right ears. 2 of the external source pots can be linked to a single pot to provide a control for an incoming stereo signal – useful for the commentator to monitor dual channel international sound. Incoming talkbacks have LEDs that illuminate if audio is detected for operators to identify the talkback source.

CMBuss System Linking
This facilitates the linking of multiple Talent Boxes, allowing programme and talkback inputs and outputs to connect to a single unit, but be shared across all connected units. Multiple commentators can therefore be added to a single programme – 30 or more if required! All mixed programme outputs on every connected Talent Box will be a mix of every input from every box. Individual direct outputs are still available on each individual box. CMBus features link technology only available to Glensound which provides quick, trouble free linking in harsh outside broadcast environments.

The Talent Box is the next generation of single unit commentary where multiple Talent Box’s can be linked to accommodate up to 30 commentators! CAT5 connections link the talkback, monitoring and programme output buses with multiple units by simply daisy chaining together if required. Glensound achieved this by developing the ‘Current Mixing System’ (CMBus) allowing the inputs on any individual system to be mixed into the common main programme, talkback and monitoring buses while maintaining low noise. Unlike traditional voltage mix techniques, the Glensound CMBus system is not susceptible to noise and interference that are prevalent in outside broadcast environments.

The talkback and monitoring inputs need only be connected to one unit in order for the CMBus to deliver their audio circuits to the relevant headphone feeds in all units. If duplicate monitoring inputs are connected on different boxes, the CMBus will mix them together enabling all commentators to monitor the source. A main programme output can be taken for any or all of the individual units. Direct outputs are not carried on the CMBus, although are available individually on each unit if required.

Link Talent Boxes for up to 30 commentators on single programme and share monitoring and Talkback
The CMBus utilises three standard RJ45 cables for linking two boxes together which are broken down in such a way that allows sets of sources to be isolated on individual boxes. This make the Talent Box’s CMBus system a truly versatile solution for multiple commentator applications.
