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 Ωto 75 ΩAES 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.
BNC to XLR
Inline Baluns
Application
Connects, extends and lengthens digital audio
cable runs by converting twisted pair to coax.
Series Features
• Signal distribution to use with video patch
panels, routers and VDAs
• Permits longer cable runs over coax
• SMPTE 276M & AES3 Transmission Standards
• Capable of carrying 2 channels AES/EBU
digital audio over coax
