dwcs2.4       Digital Wireless Conference System 

 

System Description 

 

 

 
 

 
 
 
 
 
 
 
 

 

dwcs2.4 is a new wireless conference 
system, developed by „IRP professional 

sound products",  which operates in the 

2,4GHz range. The data and audio 

transfer is full digital and all audio 

signals are digitally encoded. The 
changing digital signal encoding makes 

an unwanted hearing of the spoken 

words practically not possibly. (hearing 

security is the fundamental problem of 

all wireless conference systems, since 
these units use the UHF analog audio 

transmission. With an accordingly 

equipped UHF device it is easily possible 

to receive the discussions of a 

confidential conference in a neighbouring 
space.)  

A further considerable advantage is the 
circumstance that the signal 

transmission is 

licence-free in the 

2,4GHz range. Thus a 

local installation or a 
mobile system used 

at different locations is very simplified.   

The installation and the operation of the 

devices are comparatively simple. Except 

the connections of the antennas and the 
power cord no further cables are 

necessary. The installation of the two 

antennas is also likewise problem-free 

and easy. The microphone stations are 

carried in a special carrying case with 
integrated battery charger and are 

immediately ready for use.
