3.6.2 Audio Output
The audio output signal parameter is usually over 200mV 1k
Ω (BNC). It can directly connect to low
impedance earphone, active sound box or amplifier-drive audio output device.
If the sound box and the pick-up cannot be separated spatially, it is easy to arouse squeaking. In this
case you can adopt the following measures:
Use better sound pick-up with better directing property.
Reduce the volume of the sound box.
Using more sound-absorbing materials in decoration can reduce voice echo and improve
acoustics environment.
Adjust the layout to reduce happening of the squeaking. Please refer to Figure 3-8. It is for
audio and video output.
