By selecting “View”, the following sub-windows become available:
•
File type
•
Date & Time
•
Player
File type
From the “View”, select “File type”.
The file type window allows to select PCM (linear) or MPEG compression
recording, Mono / Stereo, sampling frequency, bit rate, file name (4
characters) and the file extension name to be selected.
•
Type
This is the audio recording method selection. Two possibilities are
available: PCM (linear non-compressed) or MPEG 1 Layer II.
•
Channels
Selection of Stereo or Mono recording. When selecting mono recording, both input channels will be
mixed to a single channel.
•
Sampling frequency
Three selections are available: 32, 44.1 or 48 kHz.
•
Bit rate
The bit rate can only be selected when recording in MPEG. Bit rates can be selected from 32 kb/s
up to 384 kb/s. Note that the full “Subjective” bandwidth is obtained if a single channel is recorded
with a minimum of 128 kb/s (stereo recording minimum 256 kb/s).
•
File name
The first four characters can be personalised. To do this, use the mouse and the left mouse button,
to highlight the characters and replace them. Once changed, click the “OK” button to enter this new
information into Nagra EMP.
•
File extension
As standard, all file extensions have the name xxx.WAV. In the case that some players, analysers
or editors are requesting a dedicated extension, apply the same rules as for the file name.
Once all the information is entered, press the “Apply” button to save those settings in the EMP recorder
(check the status bar).
Date & Time
From the “View”, select “Date & Time”.
•
Using the left or right arrows, row by row, increment or decrement
the settings. Once the correct time and date is set, press “Apply”
and verify in the status bar that time & date is updated.
The recorder contains a built-in super capacitor keeping the real time clock
running, even without batteries or external power. It will maintain the clock for up to 90 hours. If the super
capacitor is totally empty (due to long storage without battery pack), it will need minimum one minute of
charge once the Nagra EMP receives batteries or external power.
