A10-RACK

4-Slot Wireless Enclosure

Overview

The A10-RACK offers convenient mounting, powering, RF, and audio connectivity for four uni- or SuperSlot wireless receivers in its 1 RU chassis. It is designed for dual-channel receivers from Audio Limited, including the A10-RX, plus slot receivers from Lectrosonics and Wisycom. The A10-RACK includes built-in antenna distribution with powering for active antennas. Up to eight channels of audio from single or dual-channel receivers appear on both its XLR outputs and over Dante™ audio-over-Ethernet.

  • accepts up to four, two-channel wireless receivers (receivers sold separately)
  • audio output on analogue/AES3 and Dante
  • built-in power distribution
  • built-in antenna distribution with selectable power for active antennas
  • powered from 4-pin XLR input (10-18 VDC)
  • USB port for firmware updates and serial access

Dante™ audio networking offers the convenience of a single CAT5 Ethernet connection to carry the audio signal from the eight channels of the A10-RACK. Dante is alway active, whether the receiver is set for analogue or AES digital output. When used with other Dante-compatible devices, complex systems with comprehensive routing can be built. Monitoring and routing of signals from transmitters to receivers is simplified with Dante Controller, a free software application from Audinate.

RF Distribution

The A10-RACK has an integrated RF distribution amplifier. Its two RF inputs offer selectable 12 V powering for active antennas, plus loop-thru connections for another A10-RACK. A single pair of antennas can be used for up to 16 audio channels.

Powering

The A10-RACK is powered from standard 4-pin XLR, 10-18 VDC power supplies, such as Sound Devices XL-WP4 (shown right). Power supplies require 3 amps (minimum) for proper powering of the A10-RACK and connected slot receivers.

FAQ

What receivers are compatible with the A10-RACK?

  • Audio Ltd. A10-RX with A-SL
  • Audio Ltd. En2 CX2-P
  • Lectrosonics SRa
  • Lectrosonics SRb
  • Lectrosonics SRc
  • Wisycom MCR42

Can I use the Lectrosonics SRc-941 with the A10-RACK? 

The frequency range of the A10-RACK is 470-694 MHz, therefore the antenna distribution features of the A10-RACK are incompatible with the Lectrosonics SRc-941.

Does the A10-RACK output analog or digital audio? 

The A10-RACK XLR outputs are analog or AES digital audio depending on what the receiver is outputting. All receiver audio, whether set to analog or digital, is available on the A10-RACK’s Dante output. 

Can I cascade multiple A10-RACK units? 

If two or more A10-RACKs are cascaded via ‘A/B Out’ loop through, it is recommended that the slots in the first rack with antennas connected are filled up before the slots in the 2nd (or next level) are filled – this is good RF practice and will achieve best performance.

The Dante ports may also be daisy-chained if the A10-RACK is not set up for redundant operation (set to “switched” in Dante Controller).

Can I use active antennas with the A10-RACK? 

You can use active antennas on the A10-RACK. Simply switch the power switch on the front panel to the up position ( PWR+ANT) and this will enable the power to the antenna via the BNC antenna socket.
