GENERAL SPECIFICATIONS
Excellent sound performance
Advanced voice processing technology, with the unique design of the microphone, this unit can be
accurate pickup and restore the human voice through a high-quality built-in speakers or an external PA
system, original P-LINK digital ring network technology, Automatic Gain Control Volume (AGC) /
automatic frequency control (AFC) technology help reach higher volume without triggering the howling
effect, ensures each word spoken is well understood.
Complete easy-handling management
The Central Unit is the center of the system –Provide power to the whole discussion units, control the
cameras and link to other third-party devices. The 1U compact design is easily to put any where while
keep a low profile in meeting room.
Simple control with convenient recording
