MuxLab 500028 Stereo Audio Balun

The MuxLab 500028 is a stereo hi-fi audio balun designed to transmit full-range unbalanced line-level analog audio over Cat5 cabling. It suits installers and integrators who need to extend audio signals across longer distances using affordable twisted-pair infrastructure. A compatible balun is required at the far end of the cable run to complete the signal path. This unit is not intended for digital audio formats or balanced professional line levels.

Installation And Common Issues

Connection is straightforward: terminate the Cat5 cable, attach the balun at each end, and link the unbalanced stereo source and destination. The most frequent problem is using only one balun instead of a matched pair, which leaves the signal unbalanced and prone to noise. Another issue arises when the cable run exceeds practical limits for analog transmission over Cat5, causing high-frequency roll-off near the 20 kHz upper range. Ensure both ends use identical wiring standards to avoid phase or channel reversal.

Questions about this item

How can I verify the 20 kHz audio signal is passing correctly after connecting the MuxLab 500028?

Connect a source and amplifier through the balun pair using Cat5 cable, then play a test tone at the upper frequency limit and confirm clear, undistorted stereo output at the receiving end.

What comes with the MuxLab 500028 and what must I purchase separately to use it?

The unit itself is supplied; you must buy a second compatible balun and a Cat5 cable to complete the stereo audio link.
