Amplifying circuitry quality is extremely important and should posses 

high linearity, low distortion and low noise operation. 

The distance between source and acceptors plays a major role in the final 

result. If long distances (over 15 meters) exist between sources and 
acceptors - special means should be taken in order to avoid cable loss, 
such as using higher quality cables or, if necessary, line amplifiers. 

Interference from neighboring appliances can have an adverse effect on 

signal quality. Balanced audio lines are less prone to interference, but 
unbalanced audio and video lines, even though the cables are shielded, 
should be installed far away from mains carrying cables, electric motors, 
transmitters, etc.  

In some cases, either an induced interference on the cable carrying the 

signals, or ground loop problems may severely disturb the video image on 
the screen. To solve this problem, a differential video line amplifier, 
designed to eliminate the interfering signals, is needed. 

 

HOW DO I GET STARTED? 

The fastest way to get started is to take your time and do everything right the first 
time. Taking 15 minutes to read the manual may save you a few hours later. You 
don’t even have to read the whole manual. If a section doesn’t apply to you, you 
don’t have to spend your time reading it.
