ADX-140 XLR INTERFACE UNITThe 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
Four mic or line inputs with phantom power available.
Four highest-quality microphone preamps with gains remotely controllable
from the ADX-2400 in the truck.
Two IFB outputs, each of which may be 2-Channel wet (RTS format) or balanced dry.
Two channels of wet RTS-format PL.
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 required.
All PL and IFB paths are 20-bit digital for superb audio quality.
Powered via the Cat5 cable or with a wide-range AC input on the rear panel, or both.
Can provide complete stand-up or interview facilities with one compact unit.
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
