Headsets and expansion microphones
Figure 5: Placement of the expansion microphones
During a presentation, the speaker stands away from the participants. The speaker must use a
wireless headset to transmit the voice clearly to the conference phone. To double the voice-pickup
range, place expansion microphones on either side of the phone.
PA system connection
Figure 6: PA interface box in larger rooms
To encourage active participation in larger conference rooms, provide microphones for all
