NOTE
:
It is important to lower the head-shield before loading a tape, otherwise the tape may
pass behind it, and thus not be in contact with any of the heads. When the tape has been
loaded and lever (32) has been restored to its original position, the shield may be lifted in
front of the heads.
RECORDING
The NAGRA 4.2 can make a recording using either microphones or a "DIRECT" line input signal.
RECORDING WITH MICROPHONES
When using microphones, connect a microphone to one or both of the two XLR type connectors on
the left-hand side of the recorder. If the QPUT/QPAUT microphone pre-amplifiers are installed in
the recorder, check that the switches corresponding to each of the microphone inputs are in the
correct position corresponding to the type of microphone to be used. The possible selections are T-
power, +12 V and +48 V phantom, powering or 200 Ohm dynamic.
The level of the signal coming from the microphones may now be observed by putting the machine
into the "TEST" position and switching modulometer switch (12) to the "LEVEL" position. The gain
may now be adjusted using potentiometers (6) and (7) on the front panel.
Turn the main function selector to either of the two RECORD positions, depending upon whether
the limiter is required or not. Observe the modulometer to see that the levels remain correct
throughout the recording. The modulometer indicates in both RECORD modes the "Direct" signal. It
is possible to show the "off tape" signal during the recording by moving the LINE AND PHONES
snap switch to the left.
Depending on the position of "TAPE / DIRECT" switch (1) it is possible to monitor either the input
signal, or the "off tape" signal on the headphones output during the recording. This is possible
because the NAGRA 4.2 is a three head machine. (Moving this switch will not affect the recording).
RECORDING A LINE SIGNAL
Recording a line input signal rather than a microphone signal is very similar to working with
microphones. Firstly set the microphone potentiometers (6) and (7) to their fully anti-clockwise
positions. (this is to prevent any noise being amplified by the high gain microphone pre-amplifiers,
being recorded on the tape).
Connect the line input signal to the line input connector (41) on the left-hand side of the recorder.
Set the main function selector (4) to the "TEST" position and adjust the level of the incoming signal
on the modulometer by means of the level potentiometer (9) marked "LINE AND PLAYBACK".
Finally switch the main function selector to one of the two "RECORD" positions to start the
recording. When the recording is completed, select "STOP".
FAST FORWARD / REWIND
To rewind a tape put the main function selector in the "STOP" position, and open the pinch wheel
gate by using operating lever (32) then select "TEST" and rewind the tape by means of toggle
switch (23) located on the top left-hand front corner of the top deck.
When the tape is fully rewound always place operating lever (32) back in the fully closed position
(this will prevent a "flat" portion being made on the capstan "O" ring).
To wind a tape fast forward use switch (23) as for rewind. However, it is not necessary to open the
pinch roller gate. The FAST FORWARD position of the toggle switch is only active when the main
