Information:

An economical way to replace Aviom Personal Monitor mixer daisy-chain connections and individual power supplies.

With one Aviom A-Net input and eight parallel A-Net outputs, the Aviom A-16D provides an economical way to replace daisy-chain connections with star configurations. The A-16D also eliminates the need to connect a power supply at each Personal Mixer by providing power over the same Cat-5e cable that carries the A-Net audio data. Any combination of powered and unpowered connections is possible; simply connect external power supplies to the A-16D on a per-channel basis as needed.

The A-16D can also be used to provide a lossless digital copy of an A-Net audio stream (to a recording rig, for example). Simply connect an AN-16/o Output Module anywhere you want a copy of the audio. Multiple A-Net Distributors can be used in a single system.

FEATURES

• One A-Net input, eight A-Net outputs
• Can insert DC power for up to eight A-Net devices into the Cat-5e cable
• 1/2-rack-space footprint - mounts easily on standard rack shelf
• A-Net activity LEDs on the main input
• DC power indicator LEDs on each output jack
• Multiple A-16D Distributors can be used in a system
