Audio Ltd. A10-RACK

A10 Digital System

 User Guide

The A10-RACK is a 1-RU enclosure which accepts slot-in wireless receivers such as the Audio Limited A10-RX or other brand receivers.

The A10-RACK features built-in power and antenna distribution plus Dante for up to 4 two-channel slot-in receivers.

That is a total of eight channels of Dante, plus AES digital outputs, or analog outputs— all in a single, sleek, 1-RU chassis.

The A10-RACK accommodates single-channel Unislot receivers and most two-channel Superslot-compatible receivers, such as Audio Limited’s A10-RX or other models from Lectrosonics and Wisycom utilizing the D-sub 25 pin interface.

  • 4-slot wireless receiver rack system
    (receivers sold separately)
  • 8-ch Dante / AES / analogue outs
  • Receiver diversity (Unislot / SuperSlot™)
  • Built-in power and antenna distribution
  • Antenna loop-thru for 16-channel setups
  • 4-pin DC XLR input
  • USB serial port for firmware updates


The Digital Audio Network Through Ethernet protocol, better known as Dante™, allows for true networking where signal can be sent to many destinations without degradation or extra hardware. Connect the A10-RACK to a Dante network, and all eight channels of high-quality audio from the wireless receivers can be transported over a single Cat5 network cable. Monitoring and routing of signals from transmitters to receivers is simplified with the Dante Controller, a free software application from Audinate.

RF Inputs

The A10-RACK also sports RF inputs with 12V powering of active antennas, plus loop-thru connections for another A10-RACK. This provides seamless integration between two connected A10-RACKs with a single pair of antennas – resulting in reduced complexity for 16-channel configurations and additional cost savings.

Power Options

he A10-RACK is powered with a standard 4-pin F-XLR 10-18v DC power supply, like the Sound Devices XL-WP4 (shown right). This power supply should be capable of providing 3A minimum for proper powering of the A10-RACK and the slot receivers.
