Stereo Audio Balun (500027) 

Quick Installation Guide 

 

 

 

Introduction 

 
The VideoEase Stereo Audio Balun (500027) allows unbalanced line level stereo audio to 
be transmitted up to 5,000 ft (1.5km) via unshielded copper twisted pair (UTP) in a 
point-to-point connection.  The product is designed for mid-range audio applications.  
Used in pairs, the Stereo Audio Balun eliminates costly and bulky audio cable, allowing 
audio equipment to be connected or moved within a structured cabling environment.  The 
500027 also works in conjunction with other MuxLab audio-video products including the 
500200, 500012, 500001 and 500019 for a more complete cabling solution. Applications 
include; audio distribution, custom residential systems and intercom systems.
