DC Power Input
The AD2402-96 is equipped with an industry standard 4-pin XLR type power connector, and may
be powered from a 12 V battery, or from an external DC power supply.
The input voltage should be between 11 and 18 VDC.
Pin 1 = Ground
Pin 4 = +11 to +18 VDC at 0.8 A.
Pins 2 and 3 are not connected internally.
Fuse
The AD2402-96 is equipped with a 2-Amp fuse. This fuse is designed to blow if the AD2402-96
is connected to improper voltages and/or in reverse polarity. It is important to use an exact
replacement.
Digital Input Connectors
“In” Connector
This BNC connector provides a digital audio input to the AD2402-96. The digital audio input has
two functions: It can provide a phase and frequency reference to the AD2402-96 sampling
circuitry, or it can serve as an input for Digital–to-Digital processing functions.
All digital inputs and outputs are transformer coupled. The transformers isolate the
AD2402-96 from RF interference, provide protection against transients, and isolate
the internal circuitry from the effects of ground loops. DC blocking capacitors are
included to protect against damage from improper connections to phantom supplies,
or digital microphone supplies.
Use 110-ohm digital audio cable for XLR connections, and 75-ohm coax for BNC
and RCA connections.
Incorrect cable impedances may increase jitter, may cause
