ZUZONG Stereo Hi-Fi Audio Balun — Analog Audio Extender over Cat5e/Cat6

Extend your analog stereo with confidence

The ZUZONG Stereo Hi-Fi Audio Balun is a matched pair designed to carry a full-range analog stereo signal over Cat5e or Cat6 cables. By replacing bulky coax with standard Ethernet runs, you can position your audio gear more flexibly without sacrificing fidelity.

Built for hi‑fi environments, this extender preserves a wide frequency range and minimizes loss across long distances. A compact surge suppressor helps guard connected equipment against voltage spikes, while integrated ground-loop isolation reduces hum and noise that can occur on longer cable runs. This makes it suitable for both professional and home installations where clean, stable audio is a priority.

Key benefits

• Long-distance analog stereo transmission: up to 1000–1600 feet over Cat5e/Cat6.
• Plug-and-play setup with no external power required.
• Built-in surge suppression protects gear from voltage spikes.
• Ground-loop isolation helps minimize hum and unwanted noise on long runs.
• Two‑piece kit (1 transmitter, 1 receiver) for flexible deployment.

What you get and how it works

• Includes two baluns designed for analog stereo audio via RCA connectors.
• Transmit the left and right channels from the source to the destination over Cat5e/Cat6 cables.
• Simple, plug-and-play installation: connect RCA outputs to the transmitter and plug the receiver into your input component.

Technical snapshot

• Maximum input: 2 V RMS; source impedance up to 100 Ω; receiver impedance ≥ 10 kΩ.
• Bandwidth: 20 Hz–20 kHz; insertion loss per balun pair < 3 dB over the range.
• Common-mode rejection: > 60 dB at 1 kHz (and > 40 dB across the range).
• THD: ≤ 0.007% at 1 kHz across the distance range.

Ideal use cases

Boardrooms, classrooms, auditoriums, and custom home setups where a fixed audio path must traverse a distance without bulky cabling. The design supports a variety of analog sources and destinations in mixed AV environments.

Setup tips

1. Connect left/right RCA outputs from the source to the transmitter balun.
2. Connect the receiver balun to the input on your destination component.
3. Run a Cat5e/Cat6 cable between the two baluns and test the link.
4. Keep runs within recommended lengths for best performance; crosstalk may occur beyond typical distances.
