7 USING THE NAGRA-SD
Basic Introduction and General Information.
The NAGRA-SD is designed as a flexible hand-held recorder for a variety of applications. It can perform many functions, which are all covered in this
manual. The operating concept is designed around a system of 2 preset TEMPLATES in which all the required operating modes are stored. The user
can choose different parameters of the machine and these personalised settings are stored in a template for future quick access. If no specific user
Template profiles are stored then the NAGRA-SD will operate using the “default” factory settings.
This introduction covers various important global subjects. More complex operations can be understood by studying the different menus in detail. The
topics covered are:
Recording audio in the field
Replaying a previous recording
Storing settings in a template
Downloading to a computer
7.1 Recording audio in the field
General preparation:
Before making a recording the input source and compression mode need to be chosen. The NAGRA-SD makes recordings according to the preselected settings stored in the templates as well as some settings on the rear side. If nothing is set in the templates prior to the first recording, then the
“default” settings will be adopted. If specific settings are required, then they must be selected first using a previously customized template.
- Input device (external microphone / line input)
- Compression format (linear PCM, MPEG)
Select the input device in the menus. Select the compression mode using the template switch on the rear side (2 different can be stored in the
menus)as well as the file type (mono or stereo).
When ready, press the centre key (11) and the NAGRA-SD will go to the “PRE-REC” mode where the audio input can be heard on the headphones
and the levels seen on the display. The centre LED starts blinking slowly. In this mode the Pre-record buffer when turned on (max. 3 seconds) is also
active.
If the AGC is turned off, the microphone input gain can now be adjusted in 1dB steps using the keys (12 / 13), and the value is shown in a sub-window
on the display.
To begin recording, press the centre key once more (11). The red LED will flash faster and the record symbol is shown on the display. The levels can
be seen on the display and adjusted during recording as necessary, assuming the AGC is not activated.
To enter markers, during record, press the “CUE” key.
To stop recording, simply press and hold the “STOP” key (7) for 3 seconds (until the time line in the sub window is filled up).
Each new recording will be given a file name made up of 8 digits. This file will be stored in the directory.

7.1.1 The Automatic Gain Control (A.G.C)
The AGC is not an audio limiter. It operates in the digital domain and allows the operator to make recordings without under / over modulating when the
audio levels are unpredictable.
It makes recording in the field easier and guarantees that a respectable level will be recorded. Automatic adjustment systems are rarely “better” than
the manual modes, but can be considered “safer” in certain circumstances. It is also strongly recommended to switch on the low cut filter when using
the AGC for recordings in noisy environments (example: Street noise).
7.2 Playback of a previous recording
The NAGRA-SD can play back files irrespective of the current compression mode selected. To playback the last recorded file, press “PLAY / PAUSE”
and the machine starts playback immediately. To stop the playback, press the “STOP” key. To pause the playback, use the “PLAY / PAUSE” key.
If the recording was made with markers, during the playback, briefly press the “RIGHT” or “LEFT” keys to jump to the next or previous marker position
respectively.
To playback another file, briefly press the “RIGHT” or “LEFT” keys to scroll through the recorded files available. Once “PLAY” is pressed, the new file
will be played immediately.
During a playback of a file, the full “PLAY PROGRESS BAR” corresponds to the total length of the file.
When a new file has been selected for playback, the “TOTAL TIME” counter will indicate its full length and the “PLAY TIME” counter starts
incrementing once the playback begins.
During playback, to “REWIND” press and hold the “LEFT” key, to go “FORWARD” press and hold the “RIGHT” key.
7.2.1 Adjusting playback levels
The output volume level for the headphones and line output can be adjusted by the “+ OUTPUT LEVEL -” buttons in steps of 1 dB from 0 dB down to
-62 dB. This value is also shown on top of the display (HP followed by a number).
7.3 Storing settings in a template
Templates are used to store the settings for the NAGRA-SD. These templates contain the type of compression.
Templates: 2 templates are available (HIGH & LOW) and each can store the desired compression mode, sampling frequency and bit rate.
To go to the programming position, in “STOP” mode, press and hold the “FILES / MENU” until the menus appear on the display. Select “RECORD
SETTINGS” and press the right key. Select “TEMPLATE” and press the right key. Select one of the 2 templates and press the right key. Select the type
of compression and press the right key, Enter also the “SAMPLE RATE” as well as the “BIT RATE”. To quit the menus, press the left key several
times.
Once completed, the desired template can be selected on the rear side of the NAGRA-SD by selecting the “HIGH” or “LOW” template as well as the
type of recording (stereo or mono file).
7.4 Deleting an audio recording rapidly
Any audio file can be selected from the “STOP” mode by pressing the “LEFT” or “RIGHT” keys. Once the corresponding file is shown on the display,
press the “DELETE” key and confirm to delete the file.

level.
Level: This sub-menu permits to set the minimum input level before the
recording starts, or to turn off the VOR mode.
Mode: If “Pause” is selected, the recording will be paused (with default
settings: depending from the stop delay) if the level drops 25 dB below
the trigger level. If the input level rises again above the trigger level, the
recording on the same file will continue.
If “Split” is selected, the recording will be stopped (with default settings:
depending upon the stop delay) if the level drops 25 dB below the
trigger level. If the input level rises again above the trigger level, a new
record will start.
Delay: Once the VOR recording started and the input level drops 25 dB
or more below the trigger level, it allows to select the maximum
recording length before it stops.
8.1.5 Input device

9 MICROPHONES AND SETTINGS.
The NAGRA-SD can use the following microphones:
External standard stereo clip-on mic (Red band)
External mono clip-on mic (Blue band)
External high quality stereo clip-on mic (Green band)
External dynamic microphone(s) (with cable)
External Electret microphone(s) (with cable)
The standard Stereo microphone (Red band) contains two cardioïd capsules.
The high quality stereo microphone (Green band) has two cardioïd capsules inside, mounted on
special shock resistant neoprene mountings. The capsules are individually selected and matched
in both noise and gain characteristics, according to a strict selection and measurement protocol. This microphone offers a good stereo image, and is
very versatile.
The mono capsule (Blue band) is an omni-directional capsule, which offers two principal differences to the stereo capsule. Firstly, being an omni
capsule it captures much more of the ambience and is ideal for on-the-move journalism, especially because most interviews are mono. Secondly, in an
interview situation it is not necessary to “point” the microphone at the person speaking. The omni-direction characteristics allow all those being
recorded to be captured equally, hence making the journalist job less intimidating. In addition it offers longer recording times to the NAGRA-SD as the
recorded files can be mono.
The use of the foam windshield is strongly recommended with the clip-on NAGRA microphones.
Stereo Mono Stereo HQ
10 LOW CUT FILTER OR NOT ON THE NAGRA-SD
The ARES-ML is equipped with a analogue low cut filter integrated within the
microphone pre-amplifier. This filter can be turned ON or OFF as desired.
The frequency of the cut is at 100Hz with a gradient of 40 dB / octave.
This filter can be activated for each microphone type, as defined in the USER list
(DYN, NAGRA, COND……)
It is specially useful for recordings made using directional microphones outside in
windy conditions, such as the stereo NAGRA microphone. In fact, cardioïd (speed
capsules) such as the NAGRA microphone are susceptible to vortexes induced by
wind moving round the microphone capsule, contrary to omni-directional (pressure) capsules, which are not.
Note however that the NAGRA microphone is equipped with a fine silk screen directly behind the grill / basket carefully positioned to compensate for
these vortexes and “pop” effects. It is also recommended to use the external foam windshield whenever one works outside when unexpected wind
noise may be encountered.
11 AUDIO COMPRESSION (WHY AND WHEN TO USE IT).
The NAGRA-SD is able to record using different Audio qualities PCM Linear, MPEG Layer II (MP2) and MPEG layer III (MP3) that have their own
particular advantages, which are explained below.
What to use?
Firstly, the less compression used, the better the quality will be. However at higher bit rates (384 kbits/s) you can easily record music and it will
probably not notice any difference.
A few guidelines should be considered:
For journalism / interview work it is unnecessary to use PCM linear. Generally MPEG 1
Layer II is used and the compression / bit rate is generally defined by the broadcaster.
For music / effects PCM linear is the best quality although MPEG at a high bit rate is
probably good enough and gives faster download time.
For ultra long recordings use a very low bit rate, where quality will be “Dictaphone”
quality.
Some important things to remember:
- Some computers will not play MPEG 1 Layer II compressed files without an
appropriate audio editing software. Typically some versions of the Windows
Media player fall into this category.
- Audio CD’s will only accept 44.1 kHz linear PCM if they are to be played on a standard CD player.
12 USB
The miniature USB port serves two purposes: File download or external DC powering.
Audio can be extracted either through the line output in normal playback mode or alternatively via the USB port to the PC / MAC.
Connect the USB cable to the computer and to the NAGRA-SD. Power up the NAGRA-SD. When the USB is connected, a sub-window appears giving
the possibility to select “Power” or “USB communication”. Make a selection and press the “CENTRE” key.

February 9, 2011
Page 15
The USB power position is for simply powering the NAGRA-SD through the USB port for normal operation without internal batteries.
If the USB transfer is selected, the machine will immediately appear as a removable disk in the explorer of the PC/MAC. The NAGRA-SD display
shows “USB Connecting”.
On a PC or Mac, the Explorer will display a folder called “RECORD” in which all recorded indexes are stored.
- Download speed from the machine to the computer is at a fixed bit rate and the full memory (in whatever format) will take about 6 minutes
per GB to copy. This could correspond to almost 3 hours of PCM linear or equally 68h of MPEG (as an example). Looking at it from the other
direction, 1 hour of recording in PCM will take approx 5 minutes.
