2. The Digital Audio Balun works in pairs. Plug one balun into the digital audio
output (coaxial) of the digital audio source.
3. Plug a second balun into the digital audio input (coaxial) of the digital audio
decoder/amplifier at the remote end.
4. Complete the connection between the two baluns, using standard twisted pair
cabling techniques as shown below.

transformers and ballasts.
No audio Distance exceeded Verify cable length between the two
baluns.
No audio Split pair Check if the UTP pairs are split
and correct. Each signal pair must
be twisted.
No audio Power-off. Check power supplies of digital
audio equipment.
Missing channels Cabling problem
between the
decoder/amp and the
audio speakers.
Check audio speaker cabling.
Intermittent static
noise on one or
more channels.
