How ESP2™ works to make your CB sound better. 

 

The ESP2™ noise reduction system constantly monitors the signal strength 
and the type of noise present.  When the signal strength is too low for good 
reception, the receiver sound is automatically adjusted to dramatically reduce 
the noise that comes through the speaker.  While the noise is decreased the 
actual sounds you need to hear are increased. 
 
Skip interference can cause whistles and howling sounds.  Electrical 
interference from power lines, ignition systems or other sources can produce 
low humming and buzzing noise.  These high and low sounds are not 
needed for communications.  ESP2™ can determine the difference between 
undesired noises and sounds you want to hear and filter the noises out.   
 
These results ESP2™ can accomplish without decreasing receiver range (it 
usually increases range).  Most importantly, ESP2™ works by itself and does 
not need to be listening to other ESP2™ equipped CB’s to be 100% 
effective.
