Analog Input Selection - Nagra Seven Operating Instructions Manual

Analog inputs
This screen programs the analog inputs. For each input, the type of source signal (Mic. or Line) can be selected,
and +48V Phantom powering, phase inversion, filters and ALC/LIM can also be chosen. If the limiters are
ganged (Linked) then if one limiter is activated due to a strong signal then the other channel will activate
simultaneously as well.

Analog input selection

For both inputs, the LINE input can be selected as well as a choice of three different microphone sensitivity
positions, as shown below. The sensitivity of a particular microphone can be found in the respective
manufacturers' documentation, but as a guide, dynamic microphones do not require 48V phantom powering
and have a very low sensitivity and therefore require the most amplification. Condenser microphones DO need
+48V powering and provide a much stronger signal, and will use one of the other sensitivity settings.
