ADX-140 XLR Interface Panel


The ADX-140 XLR Interface Unit provides functionality similar to the ADX-120 Announce Units, but broken out to panel-mounted XLR connectors

ADX-140 XLR Interface Unit

The ADX-140 is a light weight 1RU unit which provides a combination of mic/line inputs, wet or dry ifb/line outputs, and multi-channel wet PLs all in one box. It can provide all of the audio circuits required for an interview or standup position, or used in conjunction with ADX-120 announce units to provide additional circuits in an announce booth.


ADX-140 Features

  • Available with either Audinate Dante or Cirrus Cobranet network protocol
  • Four mic or line inputs with phantom power available
  • Very high performance, extremely quiet microphone preamps with remotely adjustable gain
  • Two IFB outputs, each of which may be 2-Channel wet (RTS format) or balanced dry

  • PL1 and PL2 are combined on one XLR, and separately available with PGM1 and PGM2 on two additional XLRs
  • Four RTS-Format power supplies; two for IFBs and two for PLs. Each supply is short and overload protected
  • ADX-140 connects directly to IFB and PL beltpacks; no additional equipment reqired
  • All PL and IFB audio paths are 24-bit digital for superb audio quality
  • Two Ethernet ports for redundant network connection if desired
  • Remote control of all configuration, and remote status monitoring
  • Built-in AC power supply, or may be powered via the Cat5 network cable, or both

The 'truck end' of the system is an ADX-2400 Network Interface. One ADX-2400 supports up to four of the ADX-120 announce units and/or ADX-140 Interface Units in any combinaton. The ADX-2400 provides remote control of all functions and status monitoring of various parameters such as board temperature and PL and IFB voltages and currents. The ADX-2400 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 or media converter providing the fiber connection to the truck.
