If you use speakers, refer to "Amplifier/Active
Speaker Connection" (Page 25).
Digital Boundary Microphones (KX-VC600
only)
Up to 4 Digital Boundary Microphones can be
connected in cascade. There are no separate terminals
for input and output on the Boundary Microphones.
Also, an Analogue Boundary Microphone and
general-purpose microphones can be used
simultaneously.
Note
•
Make sure that the microphones are placed at
least 1 m away from the display and speakers.
•
Do not connect more than 4 Digital Boundary
Microphones. Doing so will cause all Digital
Boundary Microphones to stop working. If an
Analogue Boundary Microphone is also
connected, all audio input from the Analogue
Boundary Microphone will also stop working.
•
If both of the following conditions are met, the
output sent to the other party will be stereo;
otherwise, monaural:
–
The bandwidth is higher than approximately
1.8 Mbps in a 2-party video conference call
with the HD Visual Communication Unit
using SIP.
–
The MIC position is set automatically or
manually to collect a sound in stereo
(Page 92, Page 92).
•
If a headset is connected, audio from the
headset microphone is given priority, and audio
from Digital Boundary Microphones is no longer
picked up.
The range of each microphone (the radius of the circle
with a microphone at the centre) varies according to the
level of surrounding and the number of microphones
being used. Place microphones accordingly, referring
to the following table.
