RS 422 Connector (2)
This is a standard 9-pin RS 422 symmetrical serial communication port for
connection to the external world. The factory for test purposes uses this connector.
For remote controlling the Nagra-V by PC or laptop, the same connector can also
be used using the NV-COM software # 7031100000.
NOTE:
A "lap-top" style PC is not always fitted with an RS 422 port. A converter RS 232 / RS
422 must in this case be fitted to the cable to allow the communication. (ND-PCA #
7010 540 000).
Microphone Input Connectors (3)
Any type of microphone can be connected to these XLR female input connectors.
The sensitivity of the microphone inputs is selected on the front panel by the switches
#6 and the levels can be controlled by the two potentiometers #5. They are wired
according to DIN standard.

Microphone Powering Selectors (4)
Each of the microphone inputs can be switched using the switches #4 on the left
side panel of the machine, according to the type of microphone to be used. The
possible selections are Dynamic, +12V "T" power or Phantom +48V. These
switches are especially short to avoid accidental modification and need to be operated with a small
screwdriver or pen.
NOTE:
The powering requirements of any particular microphone can be found in their
respective documentation.
