Digital Audio Extender Over Cat5e/6

This extender sends digital optical or coaxial audio signals over a single Cat5e or Cat6 cable up to 500 feet. It supports uncompressed PCM and compressed surround formats including Dolby Digital, DTS 5.1 and Dolby TrueHD. The transmitter unit draws power through the cable, so only one power adapter is required at the source end. It suits installers who need long runs without signal degradation.

Passive Operation With Surge Protection

The transmitter is powered over the Ethernet link, leaving the receiver unpowered and completely silent. A built-in surge suppressor rated at 2 kV differential and 4 kV common mode guards connected equipment against voltage spikes. Power consumption is limited to the 12 VDC input, producing no audible noise or measurable heat in normal use.

Toslink And Coaxial Connectivity

Both ends provide Toslink optical and RCA coaxial ports with 75 ohm impedance and 500 mVp-p level matching. The optical interface uses a 660 nm wavelength with a maximum level of -15 dB. Solid copper 24 AWG twisted-pair cable is specified for the 100 ohm link, supporting a 12.8 Mb/s data rate and 96 kHz sampling. Buyers who require HDMI audio extraction or wireless transmission cannot use this device.

Questions about this item

How do I install the transmitter and receiver units, and what step do people often miss?

Connect the transmitter to your source via optical or coaxial, link both units with a solid‑copper Cat5e/6 cable up to 500 ft, plug the 12 V DC adapter into the transmitter only — the receiver draws power over the same cable — and verify the red LED lights on both ends.

What maintenance or replacement will this extender need over time?

No scheduled maintenance is required; the built‑in 2 kV differential / 4 kV common‑mode surge suppressor protects the audio gear, and the solid‑state design has no user‑serviceable parts — only the 12 V power adapter may eventually need replacement.

What is the first limit I will hit when running audio continuously at the maximum 500 ft distance?

The 12.8 Mb/s data rate and 96 kHz sampling ceiling cap you to two‑channel LPCM or compressed 5.1 formats such as Dolby Digital and DTS; 7.1 or TrueHD streams exceed the bandwidth at that distance.
