YC824 Digital conference system built-in speaker
YC824M Central Controller Unit
With the multiple-conference is more and more popularizationthe requesting of the meeting equipment's are higher for
the multi-functional meeting room,it need the function of video camera auto-track,voting,electing and interpretation in lots of the
discussion meeting situation Our company developed the multi-functional meeting control system on the base of summarizing the
experience of multiple-conference and speaking system for many years.This system designed by the latest digital technoogy in accordance
with lEC914and ISO standards.It's a higheffective Multi-functional meeting sstem for a meeting or conferenceand it's easy to setting-up,
debugging and using without training.

Professional Conference Amplifier
Overviews
The pro amplifier has a built-in efficient transformer and hiah capacity filter power supply.This helps ensure lower distortion, greater
low frequency control force and clearer voice when the amplifier outputs at full load. The pro amplifier offers three output modes,
including stereo,mono and bridge output.The use of time delay relay circuit allows soft startwhich helps protect the speaker against
electric shock during POWER ON or OFF.The pro amplifier is widely used on many occasions for speech transmission and sound reinforcement.
