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 Ω to 75 Ω 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.
