1. npacking and Mounting into a 19"Rack
The unit is shipped in two preset mains versions:
115VAC and 230VAC
Please check the mains voltage marking on the original package
and the voltage label on the rear panel before you connect the
unit to mains.
The voltage selection slide switch is on the left side of the unit and
covered by a plastic label to avoid accidentally changes.
The nanosyncs HD comes with the following accessories:
1 pcs IEC mains cable
1 pcs USB cable, type A-B
1 pcs Instruction manual, that you are now reading
Please check that all these items are present and contact your dealer
if anything is missing.
The nanosyncs HD housing is a standard 19" rackmount type, 1U
high.
Use four rackmount screws to mount the unit into a standard 19"
rack.
When necessary remove the bonded rubber foots on the bottom side.
Please do not mount your nanosyncs hd direct atop of equipment
with high heat emission. High ambient temperature can cause small
variations in the absolute tuning of the internal precision crystal
oscillator.
Make sure the used power socket is a 3-pole type with separate
ground conductor. Use only the provided or other 3-pole power
cables with international safety certificates.

2. Installation
Word clock cables should be under 20 metres to retain maximum
benefit from the nanosyncs HD ultra low jitter clocks.
The optimum solution is to mount the nanosyncs HD in the same 19“
rack as the most important AD/ DA digital audio converters in your
studio. These units should receive the lowest jitter sample clocks.
If you require no more than the eight word clock outputs provided by
the nanosyncs HD feed each digital audio unit a separate clock line.
If you need more clock signals you should use a word clock
distribution unit such as the Rosendahl nanoclocks.
All video and word clock cables used must be 75 ohm coaxial
(RG59). Do not use 50 ohm coaxial computer network cables
(RG58).
Most video and word clock inputs are internal terminated with 75
ohms. You can not connect two terminated inputs to one word clock
or video sync output using a BNC-T. Only if the inputs are switchable
or have no termination you can use BNC-Ts to connect multiple word
clock or video sync inputs. In this case use very short cables to link
the BNC-Ts. Ensure that only the last input of the chain is 75 ohm
terminated. Passive BNC-T links should not be used to link more
than 3 inputs. Please refer also to the instruction manuals of the
devices you connect to the nanosyncs audio clock and video sync
outputs.

5. Video Reference
To navigate through the settings you must enter the setup mode by
pressing one of the MENU keys [◄] or [►].
The currently selected parameter section starts flashing to indicate
you are in the setup mode.
With the MENU buttons [◄] and [►] you can move form one section
to the next. When saving the settings, the menu position will also be
stored and reappears at the same position when the setup mode is
called up again.
Press both menu keys (S3) (S4) to exit the setup mode and store all
settings to non volatile flash memory.
Enter the setup mode and select the video reference section with
the SELECT key.
INTERNAL: The internal 0.5 ppm accurate crystal oscillator is the
master for both video generators.
Blue LOCKED LED in the video section will be on.
An applied reference signal at the video sync input
connector will be ignored.
EXT. PAL: The unit locks to an external PAL video reference
signal applied on the video sync input connector
(C7). The 25/50 LED in the video reference section
indicates that there is a video input signal present at
25 fps. When the internal SD generator is set to
PAL 25 the outputs will be 8 field and subcarrier
genlocked to the PAL video input signal.
LEDs 24 or 24 and -0.1% indicate the detection of a
slow PAL reference at 24 or 23.98 fps.
The blue LOCKED LED in the video section indicates
locked operation to external PAL references.

- 11 -
EXT. NTSC: The unit locks to an external NTSC video reference
signal applied on the video sync input connector
(C7). The 30/ 0 and -0.1% LEDs in the video
reference section indicate that there is a video input
signal present at 29.97 fps. When the internal SD
generator is set to NTSC, the outputs will be 4 field
and subcarrier genlocked to the NTSC video input
signal.
The blue LOCKED LED in the video section indicates
genlocked operation to an external NTSC reference.
A 30 fps "black & white" input signal is indicated by
the 30 fps LED without -0.1% LED.
The nanosyncs HD will also lock to 30 fps signals.
EXT.TRI LEVEL:
The unit locks to an external Tri Level Sync signal
applied on the video sync input connector (C7).
The four LEDs 24, 25/50, 30/ 0, -0.1% in the video
reference section indicate the automatically detected
input frame rate.
When the input frame rate matches the SD or HD
generator frame rate a phase lock will be performed
(phase locked means that the according v-sync
patterns are reset exactly to the same position as
where the video input signal v-sync is located).
The blue LOCKED LED in the video section indicates
genlocked operation to an external Tri Level
reference.

- 12 -
6. SD / HD Video Generator Settings
The nanosyncs HD generates one SD video sync standard and one
HD tri level standard simultaneously.
You can set the frame rates and formats independent for the SD and
HD generator section.
Both standards are always frequency locked to the selected video
reference, also when the frame rates are different.
When using the same frame rate (or double/ half rates) the standards
will also be phase locked together (phase locked means both v-sync
patterns start exactly at the same position).
Enter the setup mode and select the SD STD. section.
Press the SELECT button to set the SD generator to NTSC, PAL 25
or PAL 24.
NTSC : 525 lines 29,97 fps, SD used in the US, Japan
PAL 25: 25 lines 25 fps, SD used in Europe …
PAL 24: 25 lines 24 fps, used for film postpro
PAL 23.98: 25 lines 23,98 fps, indicated by LEDs PAL 24
and NTSC simultaneously
Note: the generated PAL 24 signals do not insert a colour burst.
Select the HD STD. section to edit the generated HD tri level
standard, whereas "x2" indicates double frame rate as on display in
the FPS field (L8):
1080 I/PSF x2: 1080 lines, interlace or progressive
segmented frame
47.95, 48, 50, 59.94, 0 fps rates
Note: For a sync signal there is no difference between both standards.
A progressive segmented frame means progressive scanned picture
contents are transferred within an interlace frame format.

720 P x2: 720 lines , progressive
50, 59.94, 0 fps rates
720 P x1: 720 lines , progressive
23.98, 24, 25, 29.97, 30 fps rates
Go to the video generator FPS section to select the HD generator
base frame rate:
24 fps - 0.1% pull down film frame rate
24 fps standard film frame rate
25 fps European HDTV
30 fps - 0.1% NTSC frame rate (30 pull down)
30 fps US/ Japan HDTV
According to the standard listing above not all HD standards exist at
all frame rates. When you select a non-existing combination of STD
and FPS the hd video outputs are switched off and the FPS LEDs will
extinguish.
Go to the video generator SD/HD SELECT section to configure the
six video outputs VO1-VO (C1-C ):
VO1-VO3, VO4, VO5 and VO can be individually set to output the
SD or HD generator signal.
In addition VO can be configured to output black Rosendahl bi-level
syncs for Dolby Encoder/ Decoders. See page 25 nanoSETUP
software for more details.

7. Audio Reference
Enter the setup mode and select the audio reference section.
(See page 12 for more informations how to navigate through the
different setup sections.)
The audio reference can be set to:
FOLLOW VIDEO:
The audio clock generator follows to the selected video reference.
If you want to use the nanosyncs HD as a studio master set the video
reference to INTERNAL and the audio reference to FOLLOW VIDEO.
To synchronise the audio clocks to an external video reference you
must slave the video section to this external video reference and set
the audio reference to follow video.
When one of the selected SD or HD video generator standards does
match an integer relationship with the selected word clock sample
rate (for example PAL and 48 kHz) the audio clock phase will be
adjusted to the video phase.
This means that the video’s start of picture will be phase locked to
the word clock signal. Thus synchronising several nanosyncs HD to
the same house sync reference will result in phase locked audio word
clocks between all units.
The blue LOCKED LED indicates the generation of video locked
audio clock signals.
EXT. WORD FS:
When you set the audio reference to external word clock FS, the
word clock generator resolves to a defined external word clock
frequency.
In this operation mode you can select the generated sample rate
independent of the input sample rate.
You can synchronise for example a 44.1 kHz word clock signal to an
external 9 kHz word clock reference. This means the unit works as
an electronic gearbox to synchronise different sample rates together.

- 15 -
This functionality is a powerful tool when you need to convert a audio
project from one sample rate to an other using a sample rate
converter and your nanosyncs HD for locking both clocks together.
The input word clock is set with the four FPS leds in the audio
reference section and the output sample rate is set in the standard
sample rate and multiplier sections (see page 19).
The four FS LEDs in the audio reference section indicate the
selected external word clock sample rate.
These LEDs are also used to indicate the selected frame rate for
audio reference mode = LTC and the denomination left of the slash
relates to the FPS value for LTC operation and the value right of the
slash relates to the operation mode external word FS.
Example: In operation mode external word FS LEDs 25/48.0 and
30/x2 are on means the unit synchronises the audio clocks to an
external 9 kHz external word clock signal.
The blue LOCKED LED indicates the generation of gearbox locked
audio clock signals.
EXT. WORD 1:1:
Audio reference mode EXT WORD 1:1 regenerates the incoming
word clock sample rate from 40-200 kHz on all word clock outputs
1:1 (AES and SPDIF outputs are limited to Fs x2 rates up to 100
kHz).
You can use nanosyncs HD as a word clock distributor which follows
to all incoming sample rates automatically with the advantage that all
clocks are regenerated. This results in highest clock quality on all
outputs independent of the word clock input signal used.
The blue LOCKED LED indicates the locked 1:1 regeneration of
audio word clock signals.

- 1 -
The sample rate and multipliers (section L9-L13) follow automaticallly
to the word clock input signal. When audio reference is set to to EXT
WORD 1:1 it is not possible to access the sample rate and multiplier
sections in the menu.
LTC FPS:
The nanosyncs HD is also able to resolve audio word clock signals to
external, free running LTC time code signals.
Only forward running timecode within a +/- 10% window, is used as a
reference. The nanosyncs HD will perform a very slow calibration to
your time code source, which can take up to a half minute.
Once calibrated the nanosyncs HD will relock immediately to the
same speed as long as you do not change the sample rate or the
reference time code format.
Once calibrated the nanosyncs HD will flywheel over looping,
ramping and low or high speed time code with no disturbance to the
audio clock outputs.
LTC produced by analog tape recorders will be flywheeled to produce
a ultra low jitter synchronised audio clock.
Select the used LTC time code standard stepping through the FPS
section in the audio reference field.
Four LEDs indicate
24 fps, 25 fps, 30 fps, -0.1% pull down
29.97 fps is on display with 30 fps and -0.1% LEDs
23.98 fps is on display with 24 fps and -0.1% LEDs
The blue LOCKED LED indicates the generation of LTC
synchronised audio clocks.
Drop or non-drop formats are irrelevant, because this is just a speed
synchronisation process.

- 17 -
8. Sample Rate and Multipliers
Enter the setup mode and select the sample rate section (L9).
(See page 12 for more informations how to navigate through the
different setup sections.)
The base sample rate of the audio clock generator can be set to 44.1
or 48kHz.
The next section (L10) allows you to enter a so called pull factor.
These factors are special sample rates which are used in audio post
production to compensate frame rate differencies from video and film
standards.
+4% (25/24) PAL / film
+0.1% (1001/1000) 30 fps / NTSC
-0.1% (1000/1001) NTSC / 30
-4% (24/25) film / PAL
Note: For standard audio productions all four LEDs must be off.
Enter the setup mode and select the multipliers section (L11-L13).
To generate double or quad sample rates (88.2, 9 , 7 .4, 192 kHz) it
is possible to apply x2 or x4 multipliers.
WO1- (word clock outputs 1- ) are configured according (L11) to
output x1, x2 or x4 rates. Outputs WO 7-8 can be set to x1, x2, x4 or
x25 (digidesign super clock) shown in column (L12).
The AES/EBU reference outputs can be set to x1 or x2 factors (L13).
The SPDIF reference output can be set to x1 or x2 factors (L13).

- 18 -
9. LTC time code generator
From firmware 2.0 you can also start the internal LTC time code
generator manually without connecting to a host computer.
Therefor a new menu section has been implemented, indicated by
blinking LED "MMC/ MTC to LTC".
The new menu section appears next to "SPDIF" or previous to
"VIDEO REFERENCE".
Within this menu you can start and stop the time code generator with
the SELECT key.
The time code standard follows to the HD FPS section (L5) and can
be set to 23,98, 24, 25, 29,97 or 30 fps non drop standards.
The starting time defaults to 00:00:00:00 when no external time code
signal is present.
If a time code signal is applied on the LTC input (indicated by the
"LTC to MTC" LED) and the incoming time code standard matches
the HD FPS setting the unit performs a so called JAM SYNC and
takes over the time values of the external time code.
This also copies a detected 29,97 drop frame standard to the
generator when HD FPS is accordingly set to 29,97 (30 -0.1%).
The time code generator will be phase aligned to the HD video sync
generator and also to the SD sync generator if both generators are
running concurrent standards.
With different standards on the time code input and the HD FPS
section the generator can not be started in "JAM SYNC" mode.
24 and 24pd or 30 and 30pd standards can JAM SYNC each other,
but the generator will follow the HD FPS rate.
Changing the HD FPS settings while the time code generator is
running will not reset and restart the time code generator.
Please stop and restart the generator to take over a new frame rate.

10. SB midi port, MMC and MTC
The nanosyncs HD has a USB (Universal Serial Bus) port for
bidirectional communications with a host computer.
The nanosyncs HD firmware complies with the SB Device Class
Definition for MIDI Devices Release 1.0.
Current operating systems as Windows XP or Max OSX support the
MIDI device class and can be connected without installation of a
software driver.
The nanosyncs HD unit is detected as Standard Audio Device (OSX
shows also the device name as nanosyncs HD).
Any application which uses MIDI ports can use the nanosyncs HD as
midi in or out port.
LTC to MTC:
Connect a LTC time code signal to the time code input (C9). The LTC
level can vary from -40 to +20 dBu.
Forward running LTC in the range of +/- 10% of playspeed is
translated into MTC quarter messages.
All LTC formats are automatically detected and the equivalent MTC
format is used.
Time code signals running reverse or slower/ faster than the +/- 10%
range will be translated into MTC Full Messages.
MTC Full Messages serve to spot a slaved DAW to the according
time code position whereas MTC quarter messages are used for
synchronisation at play speed.
The LTC TO MTC LED (column L14) indicates that LTC time code is
read and sent as MTC to the USB midi port.

- 20 -
To synchronise a DAW to MTC time code open the nanosyncs HD
midi port in your DAW application software and make the according
settings. Please see also the instructions of your DAW software for
synchronisation to MTC.
The LTC to MTC translation is an independent process in the
nanosyncs HD and works within all operation modes.
When you use the nanosyncs HD as master clock (video reference
set to internal and audio reference set to follow video) you can still
use the LTC to MTC translation.
Example 1:
(1) A professional video machine is genlocked to the nanosyncs HD
video syncs.
(2) A digital audio workstation (DAW) is slaved to the nanosyncs HD
word clocks. The nanosyncs HD audio reference is set to FOLLOW
VIDEO.
(3) Your DAW software controls the video machine via 9-pin.
(4) The LTC output of the video machine is connected to the
nanosyncs HD and sent via USB to the DAW software as MTC.
Example 2:
(1) An analog multitrack audio tape recorder with LTC time code
recorded on track 24 feeds LTC to the nanosyncs HD.
(2) The nanosyncs HD audio reference is set to LTC.
(3) A digital audio workstation is slaved to the nanosyncs HD word
clocks/ super clocks.
(4) The DAW software receives time code from the tape machine
translated to MTC from the nanosyncs HD via USB.
