Nagra Seven Operating Instructions Manual page 38

Pre-record mode
The pre-record feature will record into a buffer memory while the recorder is in TEST position and this buffer
will be added to the start of the recording once RECORD is selected.
Pre-record time
The length of the buffer is chosen in the PRE-RECORD TIME menu. The duration can be selected to 5, 10, 15 or
20 seconds at all sampling frequencies up to 48 kHz. At higher sampling frequencies the available pre-record
time is limited to 5 seconds at 96 kHz and 1 second at 192 kHz. When active, the counter on the display will
start to count until the pre-record time is reached.
Auto-skip in playback
If set to ON then during playback the recorder will only playback files of the identical format to that of the
current machine settings, and will jump over all other files in a folder.
Start / stop polarity
The Start / Stop connector on the left side of the recorder is used for a remote "fader" start and will start or
stop the recorder in its current mode (according to the position of the main function selector) when the two
contacts are shorted together. This selection allows the polarity to be inversed so that the opposite function
will be activated when the connections are shorted together.
File format Menu
The file format menu determines all the parameters of the audio file that the recorder will make and record to
the media.
Format
This can be either 16 or 24 bits and can be set to make a single mono or stereo file (Polyphonic) or two
individual files (monophonic). The main difference between the monophonic or polyphonic formats is the
addition of the track number in the file name as "_1 or _2" in the file naming.
File name
The file name is the alpha-numeric name given to each recorded file. The file name changes depending on
whether a monophonic or a polyphonic file is being made. The file name format can be selected from a pre-
defined list of "name formats" made up of different combinations of data and are selected in the "File Name"
menu
When recording monophonic files the name formats will all end with "_#" (# = track number) for example
Tape_XXX_1.wav (for the file corresponding to channel 1) and Tape_XXX_2.wav for the file of channel 2.
The "MachName" can be programmed by the user in the "Tools" menu. The date and time settings depend
upon the settings of the real time clock and NOT the time code information.
A file can be named using a computer, but In all cases, the last 3 positions "XXX" must be a numerical value
otherwise the file will not be recognized by the Nagra. The "X" symbols in the examples correspond to the
index number in numeric digits from 0 to 9. As an example:" Beethhoven_001.wav"
