Reference Switch (9)
By pushing the switch upwards, the internal reference generator can be activated. As long as
the switch is held in this position, a sine wave of 1 kHz (at 48/96 kHz, 919 Hz at 44.1/88.2
kHz), will be present at the outputs, if the NAGRA-V is in the test position. When the
reference switch is held in the upper position during record, this signal will be recorded. No indication
is given on the modulometer. While the reference signal is activated, the input signals are muted. The
reference level is factory set to 18 dB.
Aux In and Line Out Potentiometer (10)
This potentiometer has two different functions according to the choice made in
the menu mode. If the menu is selected to LINE OUT then this pot will adjust the
Line Output level of both channels simultaneously, as well as the headphone
and loudspeaker level. Its position is memorised by the microprocessor of the
machine. That is to say, if the pot is set to the +6 dB position, then 0dB on the
meter will give a Line Output of 1.55 V or +6 dBm. If the menu is now changed to
use this pot to control the AUX IN input then the initial output setting will be stored
in the memory of the machine and will remain at 1.55V. Once the menu is set to
the AUX IN mode then this pot serves to adjust the level of the AUX Line Input coming from the 15
pole "D" type EXTENSION connector. Equally if the user changes the use of this pot back to LINE
OUT, then the previously set off the AUX IN level will be stored in the memory. These modes can be
reached using a shortcut by pressing the SHIFT key to go rapidly to input or output adjustment
(depending on the settings made in the menus).
EE / Auto / Tape (11)
EE position: Only the input signals will be available at the outputs (EE means Electronic-
Electronic). TAPE position: This position simulates the behaviour of a tape transport. The
output signals are sounds coming from the disk, the input signals when in the record mode
or in test mode, the recorded sounds when playing back, rewinding, etc.... and muted in stop. AUTO
position: This position will automatically select the EE mode or TAPE mode depending on the status
of the transport. Note: When CAM. RET (camera return) is selected, the camera return signal is
available on the speaker and headphones only in TAPE position. Switching between TAPE and AUTO
position is a fast way to select CAM.RET. or LINE OUT as monitoring source
Main Function Selector (12)
The rotary main function selector is the principle-operating switch for the NAGRA-V. It is a six position
rotary selector. Operation of each position is explained below. The present settings of the menus of
the machine will be scrolled through on the front panel display each time the machine is switched ON.
STOP. This is the main OFF position of the machine. None of the circuits of
the machine are powered in this position. When this position is selected the
machine will switch off after a few seconds if in the Power Delay menu,
Manual is not set.
If Manual is selected, the PC will remain operational. To stop the machine in
this mode the SHIFT button should be pressed and held for minimum 2
seconds while the Main selector is set to STOP.
TEST. In this position all the circuits are powered allowing the adjustment of
levels and signal monitoring. This can be considered as a "stand-by before
record" position. All menu verification and settings can be made in this position.
If the PREREC is set to ON, the record led will start blinking, and meaning that
the closed loop recording (into memory) is active.
