hearing these conversations, noise masking can be sent out of the jurors’ speakers.
Everything that transpires in the courtroom must be recorded. You can configure Converge Pro devices to accommodate
this requirement by routing all outputs to the court recorder–without gating.

BOARDROOM
A boardroom application is a good example of a situation where microphone mixing and gating become critical to
providing seamless dialogue between several people seated around a large table and at distant sites. Figure 8.3 shows
a boardroom scenario with seven participants, each with their own microphone and speaker. Also, there are observer
seating areas on the periphery of the room with speakers for monitoring the discussion at the table. Boardrooms
typically use audio and video conferencing capabilities. In this scenario, a Converge Pro TH20 is used for bringing in
phone line audio and a video codec is used for video conferencing. The Converge Pro 880 allows you to integrate both
simultaneously.
Figure 8.3 shows how audio from the video conference and program audio will come from the front left and right
speakers, which directs participants’ attention to the person speaking on the video screen. Local microphone audio is
routed to the ceiling speakers for reinforcement.
Each loudspeaker receives audio only from those microphones that are not located physical close to the loudspeakers,
minimizing acoustic coupling of microphone and speakers. This prevents feedback. This approach is easy to implement
in a Converge Pro system using the matrix mixer. Various parametric equalizers and filters might be configured for
particular microphones to enhance the voice qualities of regular participants who sit in assigned seats. All audio would
be routed to the observation areas at normal levels.
