CHAPTER 8: APPLICATIONS
The sophistication and adaptability of Converge Pro devices allows them to control and enhance many audio
applications. Following are four applications where Converge Pro forms the centerpiece of a high-quality audio system.
DISTANCE LEARNING
In a typical distance learning application, the primary source of audio comes from the instructor’s wireless microphone.
For phone-add capabilities, a telephone interface (such as the ClearOne Converge Pro TH20) would be used to transmit
sound to distant sites. Secondary audio for presentation segments can be sourced from a VCR or CD player. In larger
classroom settings, participants have desktop mics that enable everyone to hear questions and comments.
Microphone mixing and gating parameters can be set to favor the instructor’s microphone to facilitate effective dialogue
in the room. When a particular microphone gates on, nearby speakers can be attenuated or muted to reduce feedback.
Also, participant microphones can be set to gate off when secondary audio sources are in use. The left and right
speakers at the front of the room can be configured to provide stereo sound from a secondary audio source, enhancing
the training experience. All speakers can be optimized to produce full-fidelity audio by programming the Converge Pros’
parametric equalizers and filters accordingly.
Typical distance learning applications also require that video be transmitted. A video codec provides high-quality video
to facilitate a complete distance learning experience.
Figure 8.1 shows a scenario including a wireless lapel microphone for the instructor; desktop microphones for
participants; ceiling speakers to carry voice (primary) audio and some secondary audio; and left and right speakers at
the front of the room, which carry primary and secondary audio.

COURTROOM
A courtroom application requires that the sound system be precisely calibrated so that all voice audio—including that
from the judge, legal counsel, witnesses, and the jury—is easy to understand. The Converge Pro includes many features
which enhance the performance of any courtroom audio system.
ClearOne’s Converge Pro TH20 is easily integrated into the courtroom system, allowing participants on a phone line to
be heard clearly throughout the courtroom. This is an ideal addition to the system because it allows people to appear in
the court via telephone—reducing travel expenses and wasted time.
During courtroom sessions, judges might want to hold sidebar conversations with counsel. To prevent jurors from
