1. Unpacking and Mounting into a 19"Rack The unit is shipped in two preset mains versions: 2. Installation Word clock cables should be under 20 metres to retain maximum benefit from the nanosyncs HD ultra low jitter clocks. 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.
. Front Panel S1 L1 L2 L3 L4 L5 L6 L7 L8 (S1) Power Switch: Switches the unit from standby power down mode to normal operation mode and vice versa. (L1) (L2) Video Reference: The first four LEDs (L1) indicate the selected video reference. INTERNAL, EXT.PAL, EXT.NTSC or EXT.TRI LEVEL. The second column (L2) displays the detected frame rate. (L3) SD Video Generator Standard: The standard definition sync generator can be set to output NTSC, PAL 25 or slow PAL 24 /23.98.
. Rear Panel 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.
. 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.
. SD / HD Video Generator Settings 1080 P x1: 1080 lines , progressive 23.98, 24, 25, 29.97, 30 fps rates 1080 P x2: 1080 lines , progressive 50, 59.94, 60 fps rates Both standards are always frequency locked to the selected video reference, also when the frame rates are different. 720 P x2: 720 lines , progressive 50, 59.
. Audio Reference Enter the setup mode and select the audio reference section. (See page 10 for more informations how to navigate through the different setup sections.) 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.
. Sample Rate and Multipliers 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.
. LTC time code generator 10. USB midi port, MMC and MTC From firmware 2.0 you can also start the internal LTC time code generator manually without connecting to a host computer. The nanosyncs HD has a USB (Universal Serial Bus) port for bidirectional communications with a host computer. Therefor a new menu section has been implemented, indicated by blinking LED "MMC/ MTC to LTC". The nanosyncs HD firmware complies with the USB Device Class Definition for MIDI Devices Release 1.0.
MMC to LTC: 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.
MTC to LTC: 12 . Firmware Update Midi Time Code (MTC) can be generated by most DAW software. The firmware version installed in your nanosyncs HD is displayed every time the unit is switched on. When the nanosyncs HD is receiving MTC from DAW software it will trigger start the internal LTC time code generator accordingly. This means a new detected MTC signal sets the LTC generator to the corresponding position and starts the generator.
A premature termination of the software update process leads to the complete loss of the firmware but does not erase the nanosyncs HD BIOS. Please switch the unit off and on again, use the Read command and restart the firmware update procedure again.
The "special function settings" are displayed together with the firmware version each time the unit is switched on (s. page 21). "NTSC" LED in column L3 indicates activated NTSC PEDESTALS. "PAL" LED in column L3 indicates USE INTERNAL SUBCARRIER. Options -> LTC time code generator nanoSETUP utility software allows to control the LTC generator for using the nanosyncs HD as an LTC master generator. 23,98, 24, 25, 29.97, 29.
