IMPORTANT SAFETY INSTRUCTION – READ FIRST This symbol, whenever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure-voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual. Read instructions: Retain these safety and operating instructions for future reference.
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.
If the Termination LED is RED, then there is an output-loading problem, and the output may be too low to function. Try removing the 75 Ohm terminator if you added one onto this output. If that is NOT the cause, then the output may be shorted. (A defective or improperly connected cable could cause this.) If an output is unterminated or unused, the LED will not light. The SyncGen uses discrete 75 Ohm output drivers that adapt to the output load.
Diagram 1.
Connecting more than one device to an output More than one digital audio unit can be connected to a single wordclock output by daisy chaining the audio units together using either their Wordclock Thru jacks or by the use of BNC “T” adaptors. ART products with Wordclock Thru jacks are NOT terminated internally, thereby allowing easy connection of more than one device to a single SyncGen wordclock output. A 75 Ohm terminator will be required on the last unit in the chain (furthest from the SyncGen).
WARRANTY INFORMATION: Limited Warranty Applied Research and Technology will provide warranty and service for this unit in accordance with the following warrants: Applied Research and Technology, (A R T) warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials for a period of one year from the date of purchase.
