next PowerMic as possible. This helps to avoid sound interference
with the internal microphone on the wired keypad.
If you are using the wireless keypad it does not matter where you
place the keypad in relation to the PowerMic. The wireless keypad
does not have an internal microphone like the wired keypad, so
there is no potential for sound interference.
For individuals who choose to walk around during a
videoconference, an optional lapel microphone can be attached to
the front of your shirt or lapel.
The lapel microphone uses a 3-pin female cord plug on a 7.58 meter
(25-foot), permanently attached, miniature shielded twisted pair
cable. The lapel microphone cable uses a 3-pin male connector to
plug into the Audio board.
See Appendix B for information on pin assignments.
You can connect up to two additional tabletop microphones into the
electronics module as long as there are no other microphones
plugged into either of the connections on the Audio board.
The tabletop microphone uses a 3-pin female plug with a 1.2 or 7.6
meter (4 or 25-foot) detachable miniature shielded twisted-pair
cable. Like the lapel microphone, this microphone uses the same
3-pin male connector to plug into the Audio board.
See Appendix B for information on pin assignments.
The Concorde¥4500 comes standard with a wireless keypad. An
optional QuickPad can be ordered at an additional cost. The older
wired keypad can also be used with the Concorde¥4500.
The wireless keypad is used to communicate with the
videoconferencing system through an infrared (IR) remote
controlled signal. Using the wireless keypad, sound can be adjusted,
camera views altered, and video images sent from a camera.
