Palmer AoC Box XLRm – audio over Cat box with etherCON to 4 x male XLR The Palmer AoC Box XLRm is a professional audio over Cat adapter designed for sound engineers, stage technicians, and installers who need a cleaner, more flexible, and efficient way to transmit audio signals. Instead of using traditional, bulky multicore cables, this unit allows you to send up to 4 balanced analog channels or 8 digital AES3 channels over a single Cat5e (or higher) cable. This significantly improves cable management on stage, in racks, studios, and event setups where speed, reliability, and signal integrity are essential.

Key features that simplify your audio setup The device uses an RJ45 connector compliant with AES72 Type 5E and provides 4 male XLR outputs, making it ideal for structured and secure signal distribution. A major advantage is the built-in etherCON THRU port, which allows you to easily pass the signal to additional devices. Additionally, the Ground Lift switch for the RJ45 THRU connection helps prevent ground loops, which is crucial in more complex audio systems. Palmer has equipped this unit with high-quality Neutrik components, ensuring durability and reliability in both mobile and fixed installations.

Efficient signal transmission without cable clutter In practice, this means better workflow and cleaner setups. Instead of running multiple audio cables, you can rely on a single network cable for various applications. This is especially useful in live sound, event production, conferences, rehearsals, broadcast environments, and studio setups. Compatibility with 48 V phantom power further enhances usability, allowing seamless integration with equipment that requires it. The Palmer AoC Box XLRm also supports transmission of control signals such as DMX or MIDI, making it a versatile tool for modern stage and AV systems.

The signal path quality is also noteworthy. The manufacturer specifies a maximum input level of +32 dBu, a frequency response from 0 Hz to 20 kHz, and an extremely low THD of less than 0.0005% at 1 kHz and +4 dBu. For the user, this translates into clean, stable, and predictable signal transmission suitable for professional applications. When working under pressure, reliability matters just as much as sound quality. That’s why secure etherCON connectors, a robust housing, and a logical layout play a crucial role in everyday use.

Where it works best This model is an excellent choice for PA companies, stage technicians, live sound engineers, and AV installers. It performs exceptionally well in environments where compact size, fast setup, and efficient cable management are critical. You can use it on stage for microphone and line signals, in control rooms to organize connections, in conference rooms for stable signal routing, or in project studios where flexibility and order are essential. It is also a practical alternative wherever traditional multicore cables are too heavy, bulky, or simply less convenient.
