ADX-140 Interface Unit Front Panel View
GENERAL DESCRIPTION
The ADX-140 Interface Unit provides the 'field end' connections for many of the
common audio and communications requirements for live sports and other
broadcast applications, with all transmission to and from the mobile unit or studio
control room taking place via standard Ethernet.
It is intended to be used with a Lance Design ADX-2400N providing the 'truck end'
interface functions. One ADX-2400 operating in 'announce booth' mode will
support up to four ADX-140s or ADX-120 announce units in any combination. All
configuration of the ADX-140 hardware is done via remote control from the ADX-
2400 front panel.
INPUTS
The ADX-140 provides four XLR female connectors for inputting microphone or line-
level signals. Each input is equipped with a very high quality microphone preamp
with remote gain control. Phantom power is also available. An LED indicator
adjacent to each XLR indicates phantom power or line-in mode.
Inputs 1 and 2 appear as Mics 1 and 2 at the truck. Inputs 3 and 4 appear as
talkbacks 1 and 2, since these inputs make use of the paths used for talkback
signals in the ADX-120s. This does NOT represent any compromise in quality; they
are full quality paths, and intended to be used for mics or other on-air sources.
IFB OUTPUTS
The ADX-140 provides two IFB outputs on male XLR connectors. These can be
configured to be 2-channel wet (RTS-format) outputs, or +4 dBv balanced dry
outputs. In the dry output mode, either the ifb signal or the program (non-interrupt)
signal may be selected. In these modes these outputs may be used for SA
speakers, or other line-level transmission functions. The audio quality is extremely
high, making them suitable for on-air, program quality transmission.
An additional special option is to output a line-level direct output of the Mic 1 and Mic
2 preamps. This could be useful in special circumstances where an analog backup
of a microphone signal is desired.
