INTRODUCTION

The NAGRA-V is a 24 bit solid state audio recorder / player using a removable hard drive as its storage
medium (HDD). The information is stored as a digital linear FAT16/32 Broadcast Wave Format. Also equipped
with an AES input and output as well as M/S technology and weighing less than 3.5 kg (including batteries),
makes the NAGRA-V the most versatile tool available.

The front panel, metal chassis and features were all designed using the experience of previous NAGRA
recorders which render the NAGRA-V easy to operate even in harsh environmental conditions. It is powered
by a Lithium Ion rechargeable pack, NiCd, Ni Metal Hydride or eight standard "D" cells. The record autonomy
with a Lithium Ion pack is approximately 10 hours. With two 7Ah Ni Metal Hydride packs, it is 6 hours and with
8 standard 󰾽D󰾾 cells, it runs approximately 5 hours.

A set of software menus allows the configuration of the machine for selections such as Analogue or AES or
input or output routing, Time Code settings and machine configuration etc. Equipped with switchable
microphone pre-amplifiers and built-in monitoring speaker and headphone output the NAGRA-V resembles a
conventional NAGRA.

A full RS 422 communication port gives access to diagnostics for technical service, as well as PC
communication using the NV-Com Software.

This 15 pin "D" type connector serves several purposes. It has a symmetrical
transformerless Line Input (AUX), an external digital input used by the NAGRA-V as
a digital audio input (special AES input cable required: P/N 7031 140 000), left and
right IN / OUT connections for additional direct inputs and is wired for start stop

NOTE: If an external noise reduction system is connected to the NAGRA V then the two

switches inside the machine need to be moved. These two switches S1 / S2 are on
either side of the connector J12 on the box motherboard behind the modulometer.
The normal operating position of these switches is that both are towards the exterior
of the machine. That is to say S1 to the left and S2 to the right.

Chapter I 3 May 2002

RS 422 Connector (2)

This is a standard 9-pin RS 422 symmetrical serial communication port for
connection to the external world. The factory for test purposes uses this connector.
For remote controlling the Nagra-V by PC or laptop, the same connector can also
be used using the NV-COM software # 7031100000.

NOTE: A "lap-top" style PC is not always fitted with an RS 422 port. A converter RS 232 / RS

422 must in this case be fitted to the cable to allow the communication. (ND-PCA #
7010 540 000).

Microphone Input Connectors (3)

Any type of microphone can be connected to these XLR female input connectors.
The sensitivity of the microphone inputs is selected on the front panel by the switches
#6 and the levels can be controlled by the two potentiometers #5. They are wired
according to DIN standard.

Microphone Powering Selectors (4)

Each of the microphone inputs can be switched using the switches #4 on the left
side panel of the machine, according to the type of microphone to be used. The

possible selections are Dynamic, +12V "T" power or Phantom +48V. These
switches are especially short to avoid accidental modification and need to be operated with a small
screwdriver or pen.

NOTE: The powering requirements of any particular microphone can be found in their

respective documentation.

setting or the 󰾽Highest󰾾 when set to the 󰾽Stereo󰾾 mode.
The meter scale is calibrated from -󾁆 to 0 in dB however, if the meter is selected to monitor the input
signal (internal jumpers) and there is an indication above the 0dB point, this means that the A/D
converter will be overloaded. The red area (-6 to 0 dB) is the headroom area. When the BATT switch
is pressed, the green area gives information about the power status. See more information in chapter

4.
The channel being indicated depends on the position of the meter selection switch #3 on machines
fitted with the single pointer version.

Attention: From the box motherboard 9131 300 000 B, when moving the 2 internal jumpers, the
meter can be set before or after the Line Output potentiometer. This can only be done by a Nagra
Service Center. See also chapter 4.

Meter Selection Switch (3)

The NAGRA V can be supplied with either a single or double
pointer modulometer. The double meter is greatly
appreciated in Cinema or two track applications while in
Music or broadcast applications the single pointer instrument
is often preferred. In both cases, the meter is microprocessor
controlled, and has ballistics similar to those of a
modulometer. It can also be used to indicate the condition of
the power source. Fitted with two leds, it will also show the
level of the corresponding channel in the 󰾽2 Channel󰾾 menu

The meter selection switch allows the operator to decide which channel, Left, Right or

MAX, will be displayed on the meter. The MAX position will indicate the highest level
obtained between the two channels and the leds will indicate which channel this corresponds to. From
the box motherboard 9131 300 000 B, the switch will monitor the selected channel in the headphones
in Solo mode (mono). Older boards can be modified to obtain this function. In the case that the
machine is equipped with a double modulometer, the switch #3 does not influence the modulometer
but only the solo selection for the headphones.

Mem / Norm / Reset Switch (4)

This is a three-position switch. In the NORM position the meter will indicate in the normal
manner according to the signal on the input or output (depending on the selection). In the

MEM position the highest obtained level (since the last reset) will be indicated. The reset
position is a snap-switch position and is used to reset the MEM mode. This switch can be moved freely
at any time without affecting the recording. In stereo operation of the machine the function of this
switch is linked to switch #3.

Mike Level Potentiometers (5)

indicates that the input signal is so strong that the microphone pre-amplifiers are overloaded. Above
the 120 dB mark indicating 0 dB on the meter will not cause the input stages to overload but the pre­amp noise will increase.

These two potentiometers are used to finely control the sensitivity of the
microphone inputs. If the sensitivity selector is set to 0.2 mV/hPa and the level
potentiometer is set to 82 dB (maximum gain) and the modulometer shows 0
dB, this corresponds to an acoustic level of 82 dBspl.
The bold black area on the scale from 120 to 130 dB is an important indication.
If the potentiometer is set inside this area for the meter to indicate 0 dB, it
means that a 100 dB dynamic range is present. If the potentiometer needs to be
adjusted between 130 dB and 150 dB for the meter to indicate 0 dB, then this

Sensitivity Selectors (6)

switches must be set to the corresponding sensitivity. These switches are especially short to avoid
accidental modification and need to be operated with a small screwdriver or pen.

Rotary Lock (7)

Used to lock the two mike pots mechanically together. When the button is in the horizontal
position "󾁆" then the two potentiometers are mechanically locked together irrespective of

their individual positions. In the vertical position " 󾁑󾁑 " the potentiometers are totally
independent. In order for the button to be moved to the horizontal position it must be slightly
depressed.

Reference Switch (9)

By pushing the switch upwards, the internal reference generator can be activated. As long as
the switch is held in this position, a sine wave of 1 kHz (at 48/96 kHz, 919 Hz at 44.1/88.2

kHz), will be present at the outputs, if the NAGRA-V is in the test position. When the
reference switch is held in the upper position during record, this signal will be recorded. No indication
is given on the modulometer. While the reference signal is activated, the input signals are muted. The
reference level is factory set to 󰾴18 dB.

Aux In and Line Out Potentiometer (10)

This potentiometer has two different functions according to the choice made in
the menu mode. If the menu is selected to LINE OUT then this pot will adjust the
Line Output level of both channels simultaneously, as well as the headphone
and loudspeaker level. Its position is memorised by the microprocessor of the
machine. That is to say, if the pot is set to the +6 dB position, then 0dB on the
meter will give a Line Output of 1.55 V or +6 dBm. If the menu is now changed to
use this pot to control the AUX IN input then the initial output setting will be stored

in the memory of the machine and will remain at 1.55V. Once the menu is set to
the AUX IN mode then this pot serves to adjust the level of the AUX Line Input coming from the 15
pole "D" type EXTENSION connector. Equally if the user changes the use of this pot back to LINE
OUT, then the previously set off the AUX IN level will be stored in the memory. These modes can be
reached using a 󰾽shortcut󰾾 by pressing the SHIFT key to go rapidly to input or output adjustment
(depending on the settings made in the menus).

EE / Auto / Tape (11)

EE position: Only the input signals will be available at the outputs (EE means Electronic-

Electronic). TAPE position: This position simulates the behaviour of a tape transport. The

output signals are sounds coming from the disk, the input signals when in the record mode

or in test mode, the recorded sounds when playing back, rewinding, etc.... and muted in stop. AUTO

position: This position will automatically select the EE mode or TAPE mode depending on the status
of the transport. Note: When CAM. RET (camera return) is selected, the camera return signal is
available on the speaker and headphones only in TAPE position. Switching between TAPE and AUTO
position is a fast way to select CAM.RET. or LINE OUT as monitoring source

Main Function Selector (12)

The rotary main function selector is the principle-operating switch for the NAGRA-V. It is a six position
rotary selector. Operation of each position is explained below. The present settings of the menus of
the machine will be scrolled through on the front panel display each time the machine is switched ON.

STOP. This is the main OFF position of the machine. None of the circuits of
the machine are powered in this position. When this position is selected the
machine will switch off after a few seconds if in the Power Delay menu,
Manual is not set.
If Manual is selected, the PC will remain operational. To stop the machine in
this mode the SHIFT button should be pressed and held for minimum 2
seconds while the Main selector is set to STOP.

TEST. In this position all the circuits are powered allowing the adjustment of
levels and signal monitoring. This can be considered as a "stand-by before
record" position. All menu verification and settings can be made in this position.
If the PREREC is set to ON, the record led will start blinking, and meaning that
the closed loop recording (into memory) is active.

Chapter I 8 Jan 2003

RECORD. The record position, marked RECORD is the standard position
used for recording and the internal limiters (if fitted) NV-LIM #7031 130 000 will
be active and turned on (in the limiter sub-menu). When recording, the red led
beside the main function selector will be alight.
When recording, pressing the grey STOP key will automatically create a new
take number without interruption in the recording process. The position "No
A.L.C." is the position for recording without the internal limiters (if fitted).

STD. BY. In this position the grey push-button switches are activated and will
act for rewind, fast forward, skip then stop in both directions and STOP
features.
Access to all the menus & settings of the machine is also enabled.

Rewind at 80 times nominal speed.

Fast Forward at 80 times nominal speed

the five grey transport keys operate using their shifted ARROW features. As soon as
the SHIFT key is released then it will act as an ESC and the display will return to the
main display screen chosen. While in the menu mode the STOP key becomes the
EXECUTE function. When the shift key is pressed rapidly twice, it stays in the menu
mode (Flag 1 on the display is on). To remove the menu mode, press the SHIFT
key once again or move the main rotary selector to another position. A full
description of the menus is explained later in this manual.

Chapter I 9 Jan 2003

Sync mode. When the shift key is pressed and held while moving the rotary selector to the PLAY

position, the machine turns on the SYNCHRONIZER. The sync mode turns off by
moving the rotary selector.

Power delay. In the case that the POW. DELAY menu is set to MANUAL, press and hold the shift

key while turning the rotary selector to the STOP position. Keep the shift key still
pressed for 2 seconds until the machine turns OFF.

Speaker. Turning ON, OFF or selecting AUTO switching the speaker without going into the

menus, can be made by keeping the shift key pressed while pushing the BATT
switch. Every time this function is executed, it will scroll on the display through the 3
different possibilities.

In/Out pot. This give access to the mode of operation of the third potentiometer on the front

panel of the machine (AUX IN & LINE OUT) in the case that in the menu, the line
potentiometer of the NAGRA V is set to the POT.SHIFT position. That is to say that it
will adjust the input signal if the SHIFT key is kept pressed and it will adjust the
OUTPUT signal if the SHIFT key is not pressed.

Recall 1 Shortcut: When the shift key is pressed and also the left arrow key, the template

recall menus are immediately displayed.

LCD Display (14)

This is a 14 segment 8 digit back lit LCD display, permitting alpha­numeric indication of a large quantity of different information and
allowing internal settings of the machine to be made in the MENU
mode. In normal operation it will indicate the current take number and

time from the beginning of it. It is also used to display the internal
STATUS of the machine, remaining time available on the cartridge to be recorded etc. The display will
be illuminated if the illumination switch # 1 is put in the "cloud" position.

It can be used to display the following:

Banana Output Connectors (1)

This is the telephone output connection. It is a mono output fitted with a transformer with
output impedance of 600 󽿸 from 300 Hz to 5 kHz, and is used for connection to a standard
switched telephone line. The output level of this connection can be selected in the TEL
LEVEL position of the menu mode to be either 1.55V or 4.4V. When in operation, the return
feed from the telephone can be heard in the headphones or on the internal loudspeaker if
selected.

WARNING: Be sure not to connect these outputs to a mixer supplying 48V phantom as this will damage

the outputs.

AES Output Connector (3)

The 3 pole male XLR AES output connector is a digital output corresponding to the
format of the AES bus used throughout the professional audio industry. The
resolution is of 16 bits or 24 bits depending of the output settings. This connection
allows direct connection to any other digital equipment equipped with an AES
interface

Chapter I 11 May 2002

Headphone Output Jack (4)

This is a standard ¼" Stereo Jack connector. The level of the headphone output can be
adjusted using the headphone level control. When the NAGRA-V is connected to a
standard telephone line the return feed of the line is always available in the headphones.
The output pot will also affect the headphone level.

Headphone and Speaker Level Control (5)

Rotary volume control for the headphones. This potentiometer acts as if it is in series with
the output level potentiometer.

External Sync. or Video Input (6)

If the NAGRA-V is fitted with the internal Time Code option then this is the connector
where a video signal (PAL, NTSC, NTSC B/W, 75 Ohms internally loaded) or an
external work clock can be imported. The external sync input is yet another way to
synchronise the internal clocks of the NAGRA-V. The advantage of this 5V logic input is

that it can be used to control the VCXO (Voltage Controlled Crystal Oscillator) from an
external source. The input can be 44.1 kHz, 48 kHz, 88.2 kHz or 96 kHz with a logic voltage level
from min. 0.5 V to 5.0 V. This signal can be fed to the machine through the BNC connector.
Operation of the Time Code is covered in detail in CHAPTER 3 of this manual.

Time Code In/Out Lemo Connector (7)

The time code input and output is located on a 5 pole LEMO connector, the pinning of
which corresponds to that of the IV-STC, the NAGRA-D and T-Audio-TC. The time code
system of the NAGRA-V is more versatile than that of the IV-STC or NAGRA T-Audio. It
offers possibilities that were not previously available and also requires care on the part of

the operator to ensure that the correct information is being recorded and displayed at all
times.
Operation of the Time Code is covered in detail in CHAPTER 3 of this manual.
(QCTCU cable # 7016909000 󰾴 LEMO to open-ended TC cable)

Camera Monitor Return (8)

This input can be used to return the audio signal from a camera to the headphones (or
speaker) of the Nagra-V. If in the menu CAMERA RETURN is set, the selection between

the return signal or the Nagra-V inputs or playback signals is made by the EE/AUTO/TAPE
selector. In the TAPE position, only the camera return signal goes to the speaker (headphones). This
return signal can not be recorded on the disk.
The return level can only be adjusted via the menu settings. See chapter 2.

Internal Speaker (1)

This small built-in loudspeaker can be used to listen to the recordings. The Line Out level
potentiometer controls the volume of the internal loudspeaker on the front panel of the machine and
in conjunction with the headphone level pot. The speaker can be switched ON, OFF or AUTOMATIC
in the menu mode or with the combination of the SHIFT button & the BATT switch.

Front of the HDD drawer (2)

A little switch permits the powering of the HDD
drawer. In the power on position, on the left side of
the drawer, a little bracket will appear and locks it
mechannically inside the carrying bay of the
Nagra-V.

Attention: Never remove or insert the HDD from
a Nagra-V if it is in the power on mode. Always
shut down the machine, change the drive, put the

GENERAL STRUCTURE OF THE MENUS

The NAGRA V incorporates a system of menus similar to the "tree" of directories and sub­directories on the hard disk of a PC. The functions that are available via the menu mode are
in principle settings of the NAGRA V rather than operations that need to be done frequently
during normal use of the machine in the field. Menu viewing and modification is made using
shift + the grey push-button keys located on the front panel, and the 8 digit LCD display.

In this manual, all terms referring to MENUS will be written in BOLD ITALIC PRINT. For
example: select MANUAL in the Pow. Delay menu.

NAVIGATION THROUGH THE MENUS

To move up
To move down

Navigation through the menus is relatively straightforward.
There are 22 principal menus, each of which has its sub­menus, which will be explained below.

The SHIFT key needs to be

Sample text

the 󰾽FLAG 1󰾾 comma will light

on the display to indicate that the shift key is locked on and need

EXE

not be held down. Pressing the shift key again or moving the main
function selector will release it. Once the menu is displayed,
navigation through the menus is made by using the transport keys combined with the signs
above the keys.

When the user accesses a menu position using the right arrow key, the display will indicate
the currently selected setting / value. To choose an alternative, simply display the desired
choice using the UP / DOWN arrow keys, and press the EXE key to confirm the selection.

Note:

EXE

means press the EXE key. All text in blue print i.e.

2.40 GB C*2.40 GB C*Folder_A

must be

considerated as sample text.

DISPLAYING AND ACTIVATING MENUS

Menus written in CAPITAL letters may be executed. All menus written in lower case
characters (or a mix of upper and lower case) are menu tree positions that are not
executable. Example: The 󰾽Template󰾾 cannot be executed, but the 󰾽RECALL X󰾾 can be
executed. When the EXE key has been pressed a "beep" will be heard (either on the speaker
or on the headphones depending on the present setting of the beep function) to indicate that
the selection has been correctly accepted and executed.

If the display remains on the selected choice after EXE has been pressed, this indicates that
the feature has NOT been executed for some reason. This could be because it is not an
executable function or that the machine will not allow it to be selected due to other settings.

SCROLLING THROUGH THE SETTINGS

Pushing down the BAT switch briefly will scroll through the current menu settings of the
machine. If the BAT selector is briefly pushed down twice then the time code and
synchroniser settings will be shown assuming the machine is equipped with the internal time
code option.

From the main display, move left (Template) and then down to access the Sc / Tk menu.
Moving left or right from here gives access to the Scene or Take number respectively.
Once attempted the Sc or Tk menu, the first digit starts flashing. Pressing the up arrow key
gives directly access to number selection. Pressing the down arrow key gives directly access
to character selection.

Note: If a Sc / Tk name, number is entered using the spaces, once executed, they will
disappear. Example: Entering for Sc 󰾽A_12_󰾾 and execute will show afterwards 󰾽A12󰾾.

Reset TC

Moving to the Time Code menu and pressing the EXE key selects automatically the RESET
TC. Once RESET TC. Is on the display, press again the EXE key to reset.

By holding the SHIFT key and pressing the BATT. switch will change the status of the
speaker.

Go to mark

From the main display, hold the SHIFT key and press the EXE key returns to the mark
position of the index.

Battery selection forced to OTHER

Hold the BATT. switch an turn on the machine.

This solution can be used in the case that the machine doesn󰾺t switch due to the voltage level
of the battery or external power. The machine ignores the settings in the Bat. X.XX menu and
automatically selects the OTHER position which gives the largest possible voltage range.
Switching off an on again (without pressing the BATT. switch) selects again the standard
setting.

Chapter 2 7 March 2005

DISPLAY SELECTION

This is the first line of the status display, and will always indicate the pre-selected mode.
Moving to the right and scrolling, the user can see and select the different display modes
possible. This selection is automatically displayed when the machine is switched on or after a
scrolling of the selected settings has been completed. The possible selections are INDEX,
REMAIN, SC & TK, TIMECODE, and TC DELTA (the TC displays are only available if NV-TC
option is installed).

Index

When this position is selected, the display will indicate the current index
number followed by the time from the beginning of the present index, which is
indicated in h.mm.ss. The index number will automatically be incremented by
"1" each time the machine is put into record mode. This display can be used
when the machine is in all operational modes. The index number may be
incremented without coming out of record by simply pressing the EXE key
during the recording to create a new index number.

Remain

This indicates, in hours and minutes, the remaining recording time available
on the HDD according to the current settings of the machine (Sampling
frequency, bit rate etc).

Sc & Tk

When Titling is turned on, the Scene and Take naming are automatically
added in the Meta-Data of the recorded file. Every time a new record is made,
the Tk will increment by 1. If during record, the EXE key is pressed this to
start immediately a new record, the Tk will not be incremented. This is in the
case that the previous recording was considered as a false start.
Once attempted the Sc or Tk menu, the first digit starts flashing. Pressing the

This is the dynamic difference between the external time code reference and

the time code of an index while the machine is in the chase synchronise

mode.

Display 2

The second display section allows the user to program alternative display
information that can be briefly accessed each time the "SHIFT" key is
pressed. For example if INDEX is the standard display, the remaining time
may be briefly seen at any time. Releasing the "SHIFT" key returns to the
initial display.

TIME CODE SELECTION

(The Time code menus display will only be indicated if the machine is fitted with the NV-TC
time code option # 70 31120 000)

This menu allows the access and setting of all the time code options of the machine. It
permits the setting of the internal time code generator, for both TIME and USER data, as well
as frame rate selection and the time code mode. It also allows the choice of the time code to
be recorded, as well as access to the internal time code synchroniser features, including
modes of operation as well as external references to be used.

The currently selected time code menu settings can be seen on the display by pressing the

BAT switch twice in quick succession.

Gen

When the right arrow is pressed from the TIMECODE position, access is

given to all the internal generator features. Hence "in-the-field" access to

setting of all features concerning the internal time code generator.

If the down arrow is pressed from this point, the display will change to SYNC,

which allows access to all the settings of the internal time code synchroniser.

Pressing the right arrow from the GEN position will move to FORMAT

allowing all the different operating modes and features of the internal

generator to be set.

Chapter 2 9 March 2005

Format

Rec SRC

When the right arrow is pressed from the Gen. position the operator can

select the frame rate of the internal time code generator. The internal time

code generator can generate all presently used formats i.e. 24, 25, 29.97 and

30 (the latter two either with or without drop frame). The first value indicated

is the presently selected choice. The default value, automatically selected if

the memory has been lost, is 25 frames per second.

If the down arrow is pressed from the Format position the display will show

Rec.Src. This is the source selection for the time code to be recorded on the

disk. It can be set between INTERNAL, JAM SYNC, EXTERNAL or

ASSEMBLE. If set to the external position, then a longitudinal SMPTE/EBU

time code must be fed to the time code LEMO connector on the right side of

the machine in order to be recorded. The TC.EXT. flag will light on the

display as soon as an external time code is present on this connector.

If INTERNAL is selected then the internal time code generator of the

machine will be recorded.

In the JAM SYNC position, the internal time code generator of the NAGRA V

will automatically be set as soon as a valid time code is connected to the time

code input connector. If the cable providing the external time code signal is

left connected to the machine, a new jam sync will be performed

automatically as soon as the machine detects a difference between the

internal time code generator and the external signal of more than 2 ms. In

order for the jam sync function to operate when the cable is connected,

certain conditions are verified before the set is made. The incoming TC must

be at the correct speed (± 1%) for 10 consecutive frames. Frozen or reverse

time code will prevent a jam of the generator from occurring.

User Mode

If ASSEMBLE is selected each time the machine is put into REC mode a full

time code assemble will be performed. This is done by calculating the time

code value of the last frame of the previous index (taking into account the

sampling frequency) and using the next consecutive frame number as the

time stamp for the beginning of the next index. There will be no time code

discontinuity between indexes.

This menu selects the operating mode of the user bits portion of the time

code generator.

The possible modes can be either, date mode or free mode. In the DATE

position, the date in the DD.MM.YY.xx format must be used. The date will be

automatically updated at midnight (except when running 29.97 non-drop or

30 drop frame).

In the FREE mode, each digit of the user bits can be any value in

hexadecimal (0 to F).

Both of these modes also have an INC (Increment) feature meaning that the

last two right-most positions (xx) will automatically be increased by "1" each

time a new index is made in record, starting from 00 up to a maximum value

of 99.

Chapter 2 10 March 2005

Set Gen

Sync

This sub-menu gives access to the value of the internal time code generator.

FROM EXT indicates that the internal generator will be set from the external

time code on the LEMO connector, if the "EXE" key is pressed. From this

position pressing the down arrow will indicate RESET TC which will reset the

time portion of the time code system to zero, and will put the current date of

the internal clock into the user bits. If the user bits are in the free mode then

they will not be altered by the reset function. In the SET TIME menu, if the

right arrow is pressed the display will indicate 00.00.00.00 and the left most

digit will flash. Pressing the arrow keys modifies of the values of each digit as

required. Press EXE to store the new values into generator. The SET USER

position accesses the values of the user bits to be set in the same manner as

for the time code. If the generator is in the 󰾽date󰾾 mode then the numbers

entered must correspond to the DD.MM.YY.xx format. If they are in the FREE

mode then any value from 0 to F (hex) can be entered in each position.

If the Rec Src. menu is set to the ASSEMBLE position, then the Set Gen.

command will allow the time code recording to start from a given value once

the recording is started. It will effectively inhibit the assemble command for

the next recording.

This gives access to the selections affecting the internal time code chase

synchroniser of the NAGRA V. The synchroniser is activated by pressing the

SHIFT key while moving the main function selector to the play position. Be

sure that an external reference is supplied.

Offset

Chase Ref

The Offset position allows the operator to have access to the time code

offset between the "off disk" time code and the time code reference. If the

right arrow is pressed then the display will show Set meaning that the

operator has the possibility to press the right arrow again and set the offset in

hours and minutes, and then automatically the seconds, frames and bits

afterwards. This has to be done on two different display screens as there are

only eight digits and it is not possible to indicate the hours portion and the bits

of offset at the same time. Once the offset has been set, if the "EXE" key is

pressed it will be stored in the offset register. Any offset stored in the memory

of the machine will be lost as soon as the machine is powered OFF.

The RESET command will remove any previously stored offset from the

memory.

The Chase ReF. selects of the manner of synchronisation of the NAGRA V.

In the normal SYNC mode (Shift while selecting PLAY on the main selector)

the time code coming from the HDD corresponds exactly to that of the

external reference.

TC INC (incremental) means that there is an unknown time code offset

between the external reference and the time code coming from the disk.

When the machine is put into the TC INC mode the offset between the two

time codes at that exact moment is stored in the offset register automatically.

The final possibility is the VIDEO selection. In this mode the machine will lock

the time code from the HDD to the external video signal on the BNC

connector on the side of the machine.

Syncmode

Fix Clk

Var Clk

The NAGRA V has two possible clock references that affect the operation of

the synchroniser.

In the FIX CLK mode the machine will always follow the external reference.

Once the machine is in the LOCKED state the internal synchroniser will no

longer influence the transport and the transport speed is controlled entirely by

the reference frequency (REF FREQ menu). If however the synchroniser of

the NAGRA V sees an error of more than 1 frame, it will re-engage itself to

correct the synchronisation error. This is the recommended operating

mode.

This mode is designed to allow the machine, using the internal synchroniser,

to follow an external reference that is not the same as the reference

frequency selected in the menu. This setting allows the internal synchroniser

to modify the internal clocks in such a way as to follow this reference (for

example NTSC / NTSC 60). In this mode the digital output is not available

and the quality of the analogue outputs may be slightly degraded. Such a

situation arises when the recording has 30FF time code and the external

reference is NTSC (59.94). The machine will slow down to 29.97 FPS. There

will be an increase in jitter in the clocks in this mode, and should be avoided

unless absolutely necessary.

Reactime

This feature gives access to the reaction time of the internal synchroniser.

This is the number of incorrect consecutive frames that will be accepted

during the SYNC mode before the NAGRA V will drop out of the LOCKED

state. The default setting for this is 15 frames, and can be set to any value

from 15 to 999 frames (33 seconds at 30 fps or 42 seconds at 24 fps). This is

used to handle time code drop-outs during post production. The reaction time

of the internal synchroniser can be stored in a template.
