Resource Sharing (Arbitration & Tielines)
There are several tools for sharing and managing resources:
·
- to share a microphone source between multiple consoles.
·
- a one out of eight switch designed for transmission line arbitration from a matrix.
·
- a one out of sixteen switch ideal for creating a telephone hybrid selector.
·
- useful if the number of inputs and outputs you wish to share exceeds the number of
MADI links.
19.2.1 Mic Arbitration
In a situation where you wish to share a microphone source between multiple studios, the “Mic Arbitration”
function can be used to manage which system has control of the remote microphone amplifier settings (gain,
48V, etc.).
In the example above, a microphone connected to the Nova17 from the announcer's booth is to be controlled from
either of the two crystal Studio consoles. In this example, the Nova17 is the server and the two crystal consoles
are clients.
Network Control
The system works by defining a
Logic element for the microphone. You can define up to 8 sources
which may take control of the microphone. When the
Condition
signal for a source is true, then the source takes
control of the mic input parameters.
Audio Distribution
To distribute the microphone signal from the Nova17, you can use either of the following methods:
·
A direct MADI to MADI connection – where the microphone signal is available to both crystal Studios
simultaneously. The advantage and disadvantage of this method is that one studio may have access to
the mic signal without control.
·
Alternatively, configure an audio switch within the Nova17 (e.g. using a
) which is controlled by
the same condition signal as the Mic Arbitration. The advantage of this method is that when control is
switched so is the audio so that you can be sure you will never have audio without control.
