130m Stereo/Digital Audio Extender over CAT5e built in DAC

The AVPro Edge AC-AEX-KIT is a high-performance stereo and digital audio extender designed to transmit uncompressed audio signals over CAT5e cabling. Delivering audio up to 100 meters (328 feet) via UTP and extending up to 130 meters (426 feet) with STP, this system includes a built-in DAC for seamless integration across various setups. It features Power over Cable (PoC) and simultaneous optical and analog outputs for flexible audio distribution.

Ideal Use Cases

This audio extender is ideal for installations where audio sources such as SmartTVs are located at a significant distance from the audio playback system. It supports streaming audio from services like Netflix, Spotify, and Disney+, allowing users to enjoy high-quality sound throughout their home or venue. Its compact design is perfect for spaces where equipment room is limited.

Why Choose This Model

The AC-AEX-KIT stands out for its ability to support both analog and digital audio signals over long distances. It features an input DIP switch for easy selection between analog or digital sources. The Dual-Play function ensures simultaneous operation of both outputs, making it possible to serve different audio systems at the same time. It supports LPCM 2-channel and multi-channel digital audio up to 5.1 channels with Dolby Digital or DTS.

Installation and Integration

Equipped with one optical and one analog stereo L/R input, the transmitter connects to the receiver through RJ45 ports using a proprietary UTP or STP interconnect. PoC reduces the need for multiple connections, as power is delivered alongside the audio signal. The receiver provides both optical and analog stereo L/R outputs, making integration straightforward and efficient.

Each unit features a locking barrel power connection and a Micro USB port for ISP. The power supply operates on 100–240V AC, 50/60Hz, 0.8A, outputting 12V DC, 2A. The compact dimensions (22.3 x 58 x 82 mm or 0.88 x 2.28 x 3.23 inches) and light weight (0.19 lb or 0.09 kg) ensure easy installation.

Performance Highlights

The AC-AEX-KIT handles input sampling rates from 32 kHz to 96 kHz and features an input impedance of 47 kΩ, with an output impedance of 600 Ω. It consumes a maximum of 3 watts, ensuring energy efficiency. The extender maintains high audio quality over its supported distances, with UTP allowing up to 100 meters and STP up to 130 meters. Its design minimizes signal loss and interference.

ESD protection is rated at +4 kV/-4 kV for contact and air discharge, providing robust protection against electrostatic discharge.

What Makes It Different

This model distinguishes itself by offering dual audio outputs, accommodating both analog and digital sources. Its built-in DAC and Dual-Play feature allow varied connections without compromising on output options. The durable, compact chassis and locking power connector enhance reliability and ease of installation. Backed by a 10-year warranty, this device ensures long-term dependability.

Final Assessment

The AC-AEX-KIT is an excellent choice for extending audio from SmartTVs, analog stereo, or optical digital sources to distant systems. Its ability to handle UTP and STP cabling, support for PoC, and dual active outputs make it versatile for a range of installations. Choose UTP for up to 100-meter runs or STP for installations requiring up to 130 meters.
