To use the microphones
Select “EC-MIC (A7)” under “AUDIO IN” on Page 1/3 in the Audio Setup
menu. (See page 41.)
Notes on placing the PCSA-A7 microphones
• Position the microphones about 50 cm (1.6 ft) away from the participants.
• When using speakers, do not place them in front of the microphones.
Configuration using the PCSA-A7 microphones
Power is supplied to up to eight microphones connected to the Communication
Terminal or the AC adaptor, including cascade connections. However, using
the 8-meter microphone cable counts as 4 microphones.
Power is not supplied to any connected microphones that exceed this limit.
You can add more microphones, by connecting the AC adaptor to the first
microphone with no power supply.
• Up to 40 PCSA-A7 microphones can be connected to one port, using a cascade
connection.
• The POWER LED turns off on a microphone with no power supply.
The 8-meter microphone cable counts as four microphones, and power is
supplied to only the first four microphones. The same is true if the 8-meter
microphone cable is used in the middle of the connections.
