Quick Installation Guide 

Overview 

The Quad Audio Wall Balun (500033-WP-UK) allows up to four (4) analog line audio 
signals to be transmitted via a single Cat 5E/6 cable in a point-to-point connection. Used in 
pairs, or in conjunction with the 500033, the Quad Audio Wall Balun features full audio 
bandwidth response for high fidelity applications and features built-in color-coded RCA 
connectors for ease of installation. The Quad Audio Wall Balun also works in conjunction 
with other MuxLab analog audio baluns such as the 500019. Applications include; Audio 
distribution, high-fidelity sound systems, and custom residential audio systems. 

 

 
 

Installation 

One (1) pair of baluns is needed to complete one quad audio connection via Cat 5E/6 twisted 
pair. To install the baluns, perform the following steps: 

1.

 

Identify the pin configuration of the baluns. One (1) twisted 
pair is required for four (4) analog line audio signals. The pin 
configuration follows the EIA/TIA 568A/B standard. The 
Quad Audio Video Balun is reverse polarity sensitive. Please 
ensure that wiring is straight-through (Ring to Ring, Tip to 
Tip).
