Aviom D400 A-Net Distributor, 8 Powered Outputs for Personal Mixers

Aviom D400: Power and Feed Up to Eight Personal Mixers

The Aviom D400 is an A-Net distributor that takes one A-Net stream and fans it out to eight outputs, each of which both feeds audio to and supplies power to an Aviom personal mixer over a single Cat-5e cable. It accepts a Pro16e input compatible with the whole Pro16 family and delivers isolated DC power on every output, all in a 2U rack chassis. For the engineer building a stage full of personal mixers, the D400 is the hub that makes the whole system practical. It turns one network feed into a powered backbone that a room full of musicians can plug into.

Eight Powered A-Net Outputs Over Single Cat-5e Runs

The D400 provides eight A-Net outputs, and each one carries both the digital audio and the DC power a personal mixer needs over a single Cat-5e cable. That means a performer's A320 or A360 connects to the rack with one lightweight network cable and needs no power adapter at their position. Consolidating audio and power onto one cable per mixer is what keeps a large stage from turning into a tangle of cabling. Eight outputs let a single D400 serve a typical band, worship team, or theater pit directly.

Isolated Floating-Ground DC on Each Output

Every output on the D400 supplies isolated, floating-ground DC power, a design that keeps each mixer electrically independent from the others. Isolated power prevents ground loops, the hums and buzzes that occur when devices share a grounded path, which is a common problem across a large stage with many connected units. By floating each output's ground, the D400 keeps the audio path clean no matter how many mixers are connected or how far apart they sit. That electrical cleanliness is as important to a quiet monitor mix as the audio quality itself.

A Pro16e A-Net Input for All Pro16 Sources

The D400 accepts a Pro16e A-Net input, which is backward compatible with all Pro16 Series devices as well as newer Pro16e-capable sources. That means the distributor works with an AN-16/i input module, an Aviom console card, or any other Pro16 source without concern for format mismatches. Pro16e extends the original format while remaining compatible, so a system can grow without stranding existing gear. Feeding the D400 is simply a matter of running one cable from the source of the sixteen-channel stream.

An Unpowered A-Net Out for Expansion and Chaining

Beyond its eight powered outputs, the D400 has one unpowered A-Net Out that passes the audio stream along to additional distributors, output modules, or other compatible devices. This expansion port is how a system scales past eight mixers: a second D400 chained from the first adds another eight powered outputs. It also lets the same stream feed an AN-16/o output module for a recording or broadcast split. The expansion out is what turns a single distributor into the first building block of an arbitrarily large A-Net system.

A 2U Rack Chassis With Worldwide Power

The D400 is housed in a 2U, 19-inch rack chassis with an internal power supply and a rear-panel switch for 115 V or 230 V mains operation. Its internal supply and standard IEC inlet mean it drops into any equipment rack and runs anywhere in the world with the correct setting. Because it centralizes power for up to eight mixers, that single rack unit replaces what would otherwise be eight separate power adapters scattered across the stage. Centralized, rack-mounted power is exactly what makes a distributed monitor system manageable.

Simple Setup With No IP Addressing

Unlike networked systems that demand configuration, the D400 requires no IP addressing, no routing, and no software setup; connecting the cables is the entire process. A-Net is a purpose-built audio network that behaves predictably, so an engineer plugs in the source, connects the mixers, and the system passes audio and power immediately. That plug-and-play simplicity lowers the barrier for volunteer-run and quick-turnaround environments where there is no time for network troubleshooting. Reliability and ease of setup are precisely why A-Net distribution is trusted for live work.

Who the D400 Is For

The D400 is for the worship, theater, or touring engineer who needs to distribute one A-Net stream to a stage full of personal mixers and power them from the rack. It suits any Aviom rig with up to eight mixers, and it chains to serve larger systems, making it a flexible backbone as a setup grows. Installers value its isolated power and no-configuration operation in environments where uptime matters and staff may be volunteers. If you are building an Aviom personal monitoring system, the D400 is the hub it is built around.
