that may be sufficient to constitute a risk of shock. Please read the manual.
Read instructions:
Retain these safety and operating instructions for future reference. Heed all warnings printed here and on the
equipment. Follow the operating instructions printed in this user manual.
Do not open:
There are no user serviceable parts inside. Refer any service work to qualified technical personnel only.
Power sources:
Connect the units power supply to mains power only of the type described in this user manual or marked on
the power supply.
Power supply:
Use the power supply with sealed mains plug appropriate for your local mains supply as provided with the
equipment. If the provided supply does not fit into your outlet consult your service agent. Route the power cord
so that it is not likely to be walked on, stretched or pinched by items placed upon or against it.
Grounding:
Do not defeat the grounding and polarization means of the power supply.
Moisture:
To reduce the risk of fire or electrical shock do not expose the unit to moisture or use in damp or wet conditions. Do not place container of liquid on unit.
Heat:
Do not locate the unit close to excessive heat or direct sunlight, as this could cause a fire hazard. Locate the
unit away from any equipment, which produces heat such as: power supplies, power amplifiers and heaters.
Environment:
Protect from excessive dirt, dust, heat, and vibration when operating and storing. Avoid tobacco ash, drink
spillage and smoke, especially that associated with smoke machines.
Handling:
Protect the controls from damage during transit. Use adequate padding if you need to ship the unit. To avoid
injury to yourself or damage to the equipment, take care when lifting, moving, or carrying the unit.
Servicing:
Unplug power immediately if equipment is exposed to moisture, the power supply becomes damaged during a
lightning storm or if smoke odor or noise is noted. Refer servicing to qualified technical personnel only.
Installation:
Install the unit in accordance with the instructions printed in the user manual.

INTRODUCTION:
Thank you for purchasing the ART SyncGen. This product will allow you to improve the sound of your
digital recording system by providing a solid time-base reference. We hope that you enjoy the flexibility and reliability the SyncGen has to offer.
You can drive either the BNC Wordclock Input or the S/PDIF Input of your recording gear with one of
the SyncGen's outputs thereby allowing the SyncGen to work together with a wide variety of digital
audio equipment.
Using a wordclock generator will centralize all of the timing, reducing accumulated timing errors
between the individual units that make up a digital recording chain.
The ART SyncGen can also tell you about the status of your BNC wordclock cables and terminations.
You can see which pieces of gear are internally terminated, and if a cable is connected properly. A
green indicator shows correct termination. Red indicates an output that is shorted or over-terminated.
When a termination LED is unlit, the output is unconnected or not terminated.
Changing the Sample Rate
Depressing the front panel Sample Rate button will step through the six master clock rates with each
subsequent button push. The numeric display will indicate the clock frequency present at the BNC
wordclock and coaxial S/PDIF outputs. The SyncGen will also remember and maintain this sample
rate setting the next time that it is powered up.
You may however need to adjust the sample rate in other areas of your system in order to complete
the setup process. First change the sample rate setting in the recording software on your computer.
Second, some recording hardware cannot auto-detect and then lock to the incoming sample rate. In
these cases, you will need to manually set the hardware device sample rate using whatever means is
provided by the manufacturer of the hardware device, be it a software driver or a front panel control
setting.
Hooking up the SyncGen
Applying the SyncGen is a two step process.
1) Connect each audio device’s wordclock (or S/PDIF) input to the SyncGen.
2) Terminate each connection if required. (See below “Termination and why it is needed” )
All S/PDIF inputs are already terminated, therefore the SyncGen has no termination LEDs for its two
S/PDIF coaxial outputs.
Most products with a single BNC wordclock input are terminated. The SyncGen will immediately
recognize when it is connected to a device that has internal termination by illuminating the corresponding output termination LED green. If the termination LED for the output you have connected
lights Green, then you are done!
If the Termination LED is Off, then the connection requires termination. Add a 75 Ohm terminator at
the end of the cable run, either on the second wordclock input (Wordclock Thru) if available, or by
adding a BNC “T” adaptor. A BNC “T” has two female ends (for cables) and one male end (to connect
to a jack). You can buy these at RadioShack model #278-112.
