These transformerless inputs can be used for both dynamic and condenser
microphones or as analog line inputs. The sensitivity for the different
microphone input sources is selectable from 2.8 mV/pa to 40 mV/pa in the
audio settings menu. When used for analog line inputs, they will accept up
to +24 dB.
The pinning of the connectors is the standard 1 = Ground, 2 = (High), 3 =
Return (Lo)
The AES input connector is used for digital AES input signals. This selection
is made in the menus. The AES input is a standard AES 3 stereo audio input.
This connector is also used for a digital microphone according to the AES 42
format. The digital inputs are fitted with an internal SRC (sample rate
convertor) to ensure accurate synchronization is possible at all times.
This slot permits the use of removable SD memory cards. The Nagra Seven
will accept SD, SD-HC (4 – 32 GB) and SD-XC (32+ GB) type cards.To remove
the SD card, press directly on the end of the card and it will eject. Micro SD
cards may also be used with the appropriate adapter.
The LED to the left of the slot will light when the card is being addressed. It
is recommended to format removable cards using the Nagra rather than a
PC, to guarantee optimized performance. The machine does not need to be
powered down to insert or remove an SD card they can be "hot swapped".
