ADX-140 XLR INTERFACE UNIT The ADX-140 XLR Interface Unit provides functionality similar to the ADX-120 Announce Units, but broken out to panel-mounted XLR connectors.
The ADX-140 is a lightweight 1RU unit providing the following features: An ADX2400 Audio Distribution unit provides the 'truck end' of the system. One ADX-2400 supports up to four of the ADX-120 announce units and/or ADX-140 Interface Units in any combinaton. The ADX2400 provides remote control of all functions and status monitoring of various parameters such as board temperature and PL and IFB voltages and currents. The ADX2400 also provides full-flexibility routing of IFB and program inputs, talkback outputs, and PL port assignments. It also provides headphone and VU monitoring of all signals to and from the booth. The connection between the booth and the truck is Ethernet, via a variety of media. Typically fiber would be used, with an Ethernet switch in the booth providing the fiber connection to the truck via a similar switch or media converter. A single gigabit connection can support up to 48 of the ADX-120/140 units. The ADX-800 Dual Power Supply may be located with the switch in the booth and provides fully-redundant power for up to eight of the ADX-120s or ADX-140s. Since all audio traffic is a standard, registered Ethernet Layer 2 protocol, it can use standard off-the-shelf IT switches and other components. Redundancy is easily accomplished at any level that is appropriate for the application using standard IT techniques. |
