Digital Audio AES Balun  
Inline Baluns  
UniPatch System fully loaded with 16 AES  
Baluns for 64 110-75 Ohm circuits  
(allows modules to be mounted either way)  
ADC proudly offers a full series of precision Balun products: three XLR to BNC Inline Baluns;  
plus numerous Multi-Circuit Baluns that can be used in our UniPatch® system or in  
throwdown applications.  
For over 50 years ADC has been the leader in audio and video patching products with unsurpassed  
quality, reliability and innovation. To complement its full line of connectors, ADC has introduced  
a series of 110 to 75 AES impedance matching Baluns. By converting balanced signal over  
twisted pair cable to unbalanced signal over coax, the Audio Coax Balun permits the extension  
of digital audio signal transmission distances.
