1. Unpacking 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.

C1-C6 C7 C8 C9 C10 C11 C12-13

(C1- C6) SD/HD Video Sync Outputs (BNC):

Six video outputs VO1-VO6 are individually buffered to drive single
ended 75 ohm inputs. VO1-VO3, VO4, VO5, VO6 can be configured
to output standard definition sync signals or HD tri level reference
signals.

(C7) Video Sync Input (BNC):

Both internal video generators can be genlocked to external video
references using this input. The video sync input accepts SD
standard definition video syncs as well as HD tri level syncs
according to the selected video reference source. This input is
internally 75 ohm terminated and requires standard video levels.
(300mV Sync, 300 mV Burst, +/- 300mV Tri Level).

(C8) Word Clock Input (BNC):

The audio clock generator can be resolved to external word clock
signals. This input is internally 75 ohms terminated and accepts word
clock signals from 40-200 kHz at 1,5 - 5 Vpp levels.

(C9) LTC Time Code Input (RCA):

LTC time code (also called SMPTE) is read by the nanosyncs HD
and translated into MTC via the USB midi port. The audio clock
generator can also be resolved to the LTC applied on this input.
Timecode levels can vary from -40 to +20 dBu. This input is internally
terminated with 10k ohms (high impedance).

(C10) LTC Time Code Output (RCA):

The LTC time code output has a fixed output level of 1Vpp. It can
drive low impedance inputs down to 600 ohms. To connect to XLR
time code inputs a standard audio adaptor cable (RCA to XLR) is
required.

C14-C19 C20-C21 C22 C23

(C11) USB Port (USB type B):

A USB 2.0 midi device class compliant interface allows plug and play
connectivity to MAC or PC host computers (Operating systems
Windows-XP or Mac-OSX are required for the midi device class
functionality). Supports MTC and MMC as well as Rosendahl Sysex
commands for remote and update functions.

(C12- C19) Word Clock Outputs (BNC):

Word clock outputs WO1-WO6 can be configured to output base
sample rates (44.1/ 48 kHz) as well as x2 (88.2/ 96 kHz) or x4 (176.4/
192 kHz) rates. Outputs WO7-WO8 support x1, x2, x4 and also x256
(digidesign super clock) sample rates.
All outputs drive 3,5 Vpp into single ended 75 ohm inputs.

(C20- C21) AES/ EBU Outputs (XLR 3-pin):

Two AES-3 clock reference outputs can be configured to generate
standard x1 (44.1/ 48 kHz) or x2 (88.2/ 96 kHz) sample rates. These
outputs are transformer balanced and drive 3,5 Vpp into standard
110 ohm inputs.

(C22) SPDIF Output (RCA):

The IEC 985 SPDIF audio clock reference output can be configured
to provide standard x1 (44.1/ 48 kHz) or x2 (88.2/ 96 kHz) sample
rates. This output drives 0,5 Vpp into standard coaxial 75 ohm SPDIF
inputs.

(C23) Mains Socket (IEC):

Use the IEC mains cable supplied for connecting to an earthed mains
socket. Please see also page 4 "Unpacking…".

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

EXT. PAL: The unit locks to an external PAL video reference

connector will be ignored.

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.

EXT. NTSC: The unit locks to an external NTSC video reference

signal applied on the video sync input connector
(C7). The 30/60 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, 30/60, -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.
