Page 5: Detachable Battery Packs
YOU NEED POWER FIRST Introduction The Nagra-VI can be powered from one of the detachable Lithium-Ion battery packs or external DC through the 4 pole XLR connector on the left side. It can also supply power to external equipment, such as RF microphone receivers or a digital microphone, through the two Hirose connectors, each of which can supply up to 500 mA at 12V. -
Page 6: Charging Times
50/60Hz supply rated at 5A. It is fitted with a three pole LEMO connector and should only be connected to the Nagra VI battery packs. As soon as the power supply is connected to the mains, the green LED on the top of the supply will light. -
Page 7: Time Code And Real Time Clock (Rtc) Powering
External DC powering The Nagra VI may be powered through the 4-pole XLR connector on the left side of the chassis with a DC supply ranging from 9 to 16V and is designed to power the recorder from car batteries and so on. As soon as an external DC supply is connected the recorder will switch seamlessly to this supply and the battery pack on the rear will no longer be consumed. -
Page 8: Lithium-Ion Battery Life And Care
Lithium-Ion battery packs will last for between 500 and 1’000 charge cycles before being replaced, which if correctly cared for, in the case of a Nagra VI would represents about 5 years or so. However there are some important points to be made concerning the “housekeeping” of such packs. -
Page 9: External Dc Input Connector
The time code input and output is located on a traditional 5-pole LEMO connector, the pinning of which corresponds to that of the IV-STC, the NAGRA-D and T-Audio-TC as indicated. (QCTCU cable # 70 16909 000 – LEMO to “open-ended” TC cable) - Page 10 MAIN DISPLAY SCREEN The main screen of the Nagra VI is a 3½” TFT display and is used to show the status as well as levels and menus of the recorder. It was specially chosen for extremely wide “sunlight readable” viewing angle as well as its performance over a wide temperature range.

Page 19: Serial Number
Battery packs The Nagra VI comes with a 4.6 Ah Lithium-Ion battery pack NVI-BB1 (KSA# 70 32110 000) weighing 800g (1.75 lb) that will power the recorder for approximately 4 hours of continuous operation. This pack will take about 3 hours to be fully charged and it is strongly recommended to fully charge the battery before using the recorder for the first time. -
Page 20: Saving Menu Settings
General structure of the menus The Nagra VI incorporates a system of menus similar to the "tree" of directories and sub-directories on the hard disk of a computer. The functions that are available through the menus are, in principle, settings of the Nagra VI rather than operations that need to be done frequently during normal use of the recorder. -
Page 21: Menu Tree
The indications in the lower corners of some of the screen illustrations are not actually shown on the display of the Nagra VI but are used in this manual to indicate the possibilities available to the user in each position: “... - Page 22 2 and 3 are in a darker shade because they are NOT armed for recording. The ballistics of the level meters corresponds to those of a modulometer as on previous Nagra models. As soon as a potentiometer is moved, the signal level is instantly displayed on the bottom of the TFT display as a blue “fuel gauge” with the corresponding input number and audio sensitivity in dB SPL clearly indicated.
-
Page 23: Line Inputs
Inputs 5 – 6 also double up as two digital inputs marked AES A and B. The audio chain of the Nagra VI will accept audio frequencies up to 45 kHz, and this can be recorded assuming the 96 kHz sampling frequency is used. - Page 24 The AES device connected to the AES input of the Nagra VI must be selected as the reference for the Nagra VI. The clock signal of this external device should also be fed to the clock signal input of the other AES device in use.
- Page 25 REC: This is the channel “arming” selection. It is in parallel with the selections in the file format menu and indicates which channels will be recorded on the Nagra VI. For inputs 5 and 6: Only analogue Line or AES inputs can be chosen. A mute position is added in the event that the user has already used input 5 or 6 for an AES signal for another pair of channels, allowing the “unused”...
-
Page 26: Input Filters
Wind noise coming into the pre-amplifier will already have done its distortion and overloading directly in the pre-amplifier long before it gets to the digital filtering stage. The filters in the Nagra VI roll off - 3db at 250 Hz and then at 12 dB per octave. If an alternative curve is required, then provision is made on the input circuit board to add capacitors accordingly and the necessary values can be supplied if necessary. -
Page 27: Playback Mixing
The Mixer menu The internal mixer of the Nagra VI is designed as a 6 to 2 mixer where the inputs of channels 1 to 6 can be mixed and then sent to the outputs or recorded on tracks 7 and 8. -
Page 28: Line Input Level Adjustment
Microphone display scale selection The microphone display scale menu permits to adjust the scale of the level indication “fuel gauge” so that it will correspond to the actual dBSPL value according to the specific sensitivity of the microphone being used. If the sensitivity of the microphone is known (supplied by the manufacturer in the technical specifications of the microphone), select the corresponding sensitivity for the microphone. -
Page 29: M/S Decoders
M/S Decoders As the Nagra VI has 4 microphone inputs, two M/S decoders are available. The M/S decoder only acts on the headphones and not on the outputs (unless the outputs have been set to the monitoring output mode in which case the M/S decoder will also affect the outputs). -
Page 30: Headphone Outputs
Headphone outputs The Nagra VI is equipped with two parallel headphone outputs. The signals fed to these outputs, depends on the positions of the monitoring matrix switches above the main function selector. The headphone level of both outputs is adjusted using the headphone level pot on the front panel. -
Page 31: Line Output Level Adjustment
A high quality analogue output is located on the right side of the recorder on the two XLR connectors. It can be set to feed out channels 1 + 2, 3 + 4, 5 + 6, 7 + 8, Monitoring output, the output matrix and the mixer output as desired, using the menu. -

CHAPTER III (Part 3) THE M E D I A DRIVES, FOLDERS, FILES, DIRECTORY Indexes / Takes Definition of terms This is an area which although logical and straight-forward can lead to some confusion if not clearly understood. This section aims to clarify the different areas and explain the use of the different terms. Term Definitions Working Drive :... - Page 33 The INTERNAL HARD DISK The Nagra VI is delivered with an internal 120GB Hard disk. This can be replaced if desired but the new disk must be a 2 ½” Parallel ATA type (PATA) of any size up to a maximum of 2 Terabytes. Equally the internal disk may be completely removed (physically disconnected) if the machine is to work in extreme conditions (for example at -30°...
- Page 34 The working folder (on HD, CF or USB drive) is stored on the working disk (in the NagraVI.ini file). Thus, as an example, if a certain working folder is used on a CF, and this card is put into another Nagra VI and CF is selected as the working drive, the recorder will automatically find the correct working folder on the card.
-
Page 35: Changing The Working Folder
To change the working folder, in the folder menu select the internal disk or Compact flash card, press the right key and choose a folder. The Nagra VI is now ready to work with this folder. The currently selected working folder has the sign “>” in front of the folder name. An error message “Used for Copy” will be displayed if this is attempted during the copy process. - Page 36 Viewing folders on PC via USB If the Nagra VI is connected via USB to a PC then seen via a PC Explorer, it will immediately be recognized as an external generic drive called “NAGRA_SOUND” of the computer, the following can be seen on the PC...
- Page 37 “.WAV” The Nagra VI can record either a single polyphonic file containing any (or all) of the eight tracks for each .wav file, or it will record up to eight individual monophonic files – one for each track for every recording.
-
Page 38: File Sizes
Note: It is not possible to record an index higher than 299 the machine will not go into record even if the disk is not full. Even if index # 299 is the ONLY recording in the folder, the Nagra VI will still inhibit additional recordings (“Directory full”... - Page 39 If playback of a track recorded at a sampling frequency other than the currently selected frequency is attempted then Nagra VI will temporarily change to this sampling frequency. It will automatically revert to the internally selected frequency if TEST or PRE-REC or REC are selected.
- Page 40 Renumber all Renumber all the indexes in the directory consecutively starting from “001”. This command is followed by “Press right to confirm”. Note: The functions “Renumber”, “Renumber all”, and “delete…..” are NOT authorized during recording, although “Copy” and “Delete” (a single take) are allowed. Create report Will generate a list containing all the directory information concerning the current working directory.
-
Page 41: Metadata Entry
Each portion of this data (Scene, names etc) can be edited using the main display of the Nagra VI. This additional information is recorded at the “head” of each file which is an additional “Chunk” of information and is interpreted along with the audio file. -
Page 42: False Start
This cannot be combined with a Wild-track, only one or the other can be selected. Note: The Pick-up scene tag is not a formal iXML flag and is simply added by the Nagra VI to the end of the scene name. If the scene name already consists of 12 characters then the last two characters will be replaced by “-P”... -
Page 43: Copy Menu And Display
How the copy function works The Nagra VI uses its copy manager to manage a “copy list”, which can contain up to 20 items. Each index or folder to be copied is added to this list as a copy “item”. A list item contains the drive, the folder name and the index range to be copied. -
Page 44: Copying Indexes
Auto copy The Auto copy feature can also be considered as an automatic back-up of the current recordings, and once activated, requires no further user input. The copy menu offers two options, Copy manager and Copy setup. Select Copy setup and move the cursor to the Auto copy position and check the “autocopy”... -
Page 45: Copy List
COPYING The copy process is running. SUSPENDED The Nagra VI is in record mode and the current copy destination is the same drive as the working folder (copy will always go to the other drive). The copy is suspended to avoid file fragmentation on the disk and to guarantee you a reliable remaining recording time. -
Page 46: Copy Error Messages
The next function is available when the power to the Nagra VI was lost prior to finishing a copy. This is the only function possible in this case. Retrieve Retrieve the uncompleted copy list items prior to power off. This function does not clear the error. - Page 47 ERASE a folder while the selected indexes or folder is still in the copy list. You have put the Nagra VI in power off and it has not yet finished to copy, this is not an error message in this case (see copy and power off section).
-
Page 48: Copy And Power Off
Copy and power off If the Nagra VI is still copying and you don't want to wait for the process to finish. No problem! Put the main selector to the OFF position, it will display the message Copying. The Nagra VI will finish all the copies in the list, and will then power off automatically. - Page 49 CHAPTER III (Part 4) THE S E T- U P The OTHER SETTINGS >>>> > All the other settings apart from AUDIO are covered below. They correspond to the personalization parameters of the recorder, and are all functions and features that can be stored in the templates. The settings screen is shown below.
-
Page 50: Potentiometer Offsets
When the main selector is moved from TEST to REC, the contents of the buffer will immediately be recorded at the beginning of the recording as if the Nagra VI were already in record prior to the moment the actual recording is activated. - Page 51 because as far as the recorder is concerned, it is already in the RECORD mode albeit “loop recording” to the buffer, and such changes are not permitted in the record mode. Chapter III July 2010 (Part 4 – The Set-up)
-
Page 52: Clock Reference
Clock reference This is the reference frequency selection that tells the machine to which signal the internal clocks of the machine are to be synchronised. Generally the machine will be synchronised to its internal high stability stratum III crystal (MASTER position), which will guarantee the correct sampling frequency. - Page 53 Sampling frequency This selection is used to select the sampling frequency of the internal audio A/D converters, and to select the necessary internal clock frequencies. If a sample frequency such as 48’048 is to be recorded then simply set the sampling frequency to 48 kHz and then set the Clock reference to Master + 0.1%.

Page 54: Colour Themes
(or “files” in monophonic mode) reaches the selected maximum the Nagra VI will automatically create a new index seamlessly. It should be pointed out that although the Nagra VI can handle files up to 4 Gb (max. authorized in FAT 32) many editors, and other post-production devices will not handle them. This feature enables recordings to be broken into portions suitable for other media. - Page 55 Four different displays can be selected for the standby (Status), recording and playback screens. The “Standby” screen is the screen displayed when the Nagra VI is NOT in record mode (i.e. Stop, Test of Play). When the main selector switch is moved from the TEST to the REC position the screen will change to the pre-set selection.
- Page 56 The Beep function The beep function of the Nagra VI can be used to alert the user to certain events. It consists of two musical tones of “C” and “G” (“do” and “sol”) and is set to a level of -18dB. The following beep indications are...
-
Page 57: Meter Programming
User Programmable Keys The Nagra VI has three user definable keys U1, U2 and U3 on the front panel. These keys can be programmed to short-cut the path to any of the menu positions. This allows the user to access three different menu positions at the simple press of a button. -
Page 58: Media Speed Test
Media Speed Test mode, to allow the user to test different media to verify its suitability for use with the Nagra VI, and to indicate the electronic digital “id” of the CF card being used. In the picture above the CF card is a Sandisk SDCFM-1024, this is very useful to be sure that the CF card being used is not a low cost “clone”... - Page 59 Compact flash cards can be formatted on a PC, however to ensure that the cluster size is optimized for use in the Nagra VI is strongly recommended to format the CF cards in the Nagra VI rather than using a computer.
-
Page 60: Machine Name
Machine name This is used to enter a name for the Nagra VI to be used in the file name (if selected). To change the name, press the centre key to enter in the editing mode. Use the up / down keys to select a character. Use the right / left key to jump to the next character position. - Page 61 USB Keyboard Layout The Nagra VI will allow an external USB keyboard to be connected to the USB “Host” connector. An external keyboard makes the introduction and modification of data (TC, METADATA etc) much easier. Connection of a USB keyboard also allows navigation throughout the menus of the machine, as well as machine transport functions to remotely control the Nagra VI.
-
Page 62: Disk Information
This sub menu shows some important information about the recorder. The first line shows the serial number of the Nagra VI which is burned into the software and cannot be erased. The hardware version corresponds to the electronic circuits which are installed in the machine. The currently installed software version is also indicated. -
Page 63: Software Updates
Software updates Updating software of the Nagra VI is very straightforward, although a simple procedure needs to be strictly followed. To update the version of internal software, use a blank compact flash card or USB key of minimum 256 MB. - Page 64 Secondly the templates can be created or modified on a PC and then recalled into the Nagra VI which is a very fast and simple way to operate. They can be edited with a text editor (such as Notepad / Wordpad).
-
Page 65: Time Code In Digital Recorders
The T I M E C O D E Time code introduction The Nagra VI is delivered as standard with an internal time code system. Time code is used for two principal operations; Synchronizing the audio recordings to the corresponding video / film images in post production and secondly for localizing events during recording. -
Page 66: Frame Rates
The time code system of the Nagra VI is able to follow variations in the external clock of up to ±4% When using an external clock this coherence will remain perfect as long as the machine is still powered. -
Page 67: Time Code Pull-Up / Down
Nagra VI does NOT ask for the date and time to be set by the user (Not TC date and time) then this guarantees that the TC is still accurate as both the TC and RTC use the same crystal. - Page 68 longitudinally in parallel with the audio as in analogue recorders). This does mean that for the time code to be read by another device (for example a PC) the program reading the file must be capable of interpreting the header information, otherwise only the audio will be played back. At the moment a recording is started the time code to be recorded is corrected according to the pre-record buffer duration setting, thus keeping the time code coincident with the audio start point.
-

Page 70: User Bits
Selecting set from Ext. and pressing the centre key sets the internal time code generator of the Nagra VI to the external time code signal connected to the LEMO connector. Selecting RTC and pressing the centre key will set the time code hours, minutes and seconds from the internal real time clock of the recorder, allowing a very rapid TC setting. -
Page 71: Sync Mode
Note: If the synchronizer (or goto function) are sent to a “gap” in the time code, the Nagra VI will oscillate between the two “ends” of the gap and the chase / goto function will be aborted after a short time. -
Page 72: Error Messages
You have put the Nagra VI in power off and it has not yet finished to copy, this is not really an error message in this case. (see copy section). -
Page 73: Problem Solving
“Aborted” The copy process was requested to stop by the user, cleaning of the partially copied index. Problem solving This table is not aimed to cover every single eventuality that may occur. However it is designed to cover the most frequent situations that may occur in daily use, which are generally due to a simple setting error that may take a long time to locate otherwise. -
