Teleconferencing
As teleconferencing becomes a more popular way of conducting “face-to-
face” electronic meetings, sophisticated equipment will make the difference
between an average (or even frustrating) meeting and a high class, perfectly
managed meeting. Executives at all levels appreciate the carefree ease of use
that the MPAII provides for electronic meetings.
The benefit derived by using the MPAII in teleconferencing is its ability to
use multiple, gating microphones. This keeps unused microphones closed,
preventing extra noise, reverberation, echo, etc. When someone speaks at
the “closed” microphone, it will automatically gate on for the period it is in
use (if properly programmed).
When the MPAII is used at multiple sites, and linked through telephone
connections, each site can program its MPAII to accommodate the type of
conference (audioconference or videoconference) and the size of the
conference room. The MPAII can be easily programmed to tailor each
system to the application. The program allows you to specify: adaptive
ambient mode, ambient level (dBu), constant gain mode, decay rate, first-mic
priority mode, gate ratio (dB), hold time (tenths/a second), last-on mode,
maximum number of microphones, off attenuation (dB) and PA adaptive
mode.
With the LOGIC OUTPUT connector, electronic equipment such as cameras,
signs, etc. can be managed, performing functions necessary for successful
conferencing.
Other Gentner products frequently used with the MPAII in this type of
application include the TI7200 Teleconferencing Interface, G3200 Super
Hybrid, GT300 Group Teleconferencer, GT700 Group Teleconferencer and
GT724 Group Teleconferencer (Figure 34, below).
Each of the teleconferencers connects your telephone line into your
conference, enhancing your conference with echo cancellation, echo
suppression, and cleaner, clearer audio quality.
