Audio Connections
There are two distinct audio connection sections on the SilverBack V camera unit. The first are the two
miniXLR MIC/Line inputs adjacent to the intercom headset connector. These analog inputs are used for
applications requiring MIC level or the flexibility of switching between MIC and Line level. These inputs
are setup in the System menu. Gain is fixed at unity when set to Line mode. In MIC mode, gain is
adjustable and 48V phantom power can be enabled. Two 3-pin miniXLR-M to XLR-F adapter cables are
included with the system.
The other audio connector is a high-density 26-pin MDR connector. This provides bidirectional four-
channel analog Line/AES connectivity, mimicking the DB25 on the base unit. These inputs and outputs
are configured using the System menu as either analog Line level or AES, on a stereo-pair basis.
