In annex B, the AES11 standard also describes common practice in transmitting and receiving a plain word clock signal. In this context, the word clock is known as a Digital Audio Reference Signal (DARS). The AES11 standard defines a means for carrying a word clock over an AES3 connection. The length and quality of coaxial cables are important. Using clock distributing devices for parallel transmission is a better method. Ī chain connection from the source through the receivers may increase jitter.
The amazing word clock manuals#
An unfortunate aspect is that some equipment manuals do not indicate whether a hardwired terminator is included. Some digital equipment includes a switchable terminator, some include a hardwired terminator and others have no terminator at all. It prevents the clock signal from reflecting back into the cable and causing false detection of extra 1's and 0's. Proper termination of the word clock signal with a 75ohm resistor is important.
Items that should remain consistent are TTL level, a 75ohm output impedance, 75ohm cables and a 75ohm terminating resistor at the end of a chain or cable. Although the electrical characteristics of the word clock signal have not been completely standardized, some characteristics should always apply.

The amazing word clock code#
Time code can be used as an initial phase reference for jam sync using the word clock as the frequency reference. Timecode is metadata about the media data being transmitted. Word clock should not be confused with timecode word clock is used entirely to keep a perfectly timed and constant bitrate to avoid timing errors that can cause data transmission errors. It allows all the components in the signal path to process the data and remain synchronized with each other. The signal is used for synchronizing digital audio signals between devices, such as CD players, audio I/O cards, etc. The device which generates the word clock is the clock source for all the other audio devices. Various audio over Ethernet systems use communication protocols to distribute word clock. S/PDIF, AES/EBU, MADI, ADAT, and TDIF are some of the formats that use a word clock. Word clock is so named because it clocks each audio sample. In digital audio electronics, a word clock or wordclock (sometimes sample clock, which can have a broader meaning) is a clock signal used to synchronise other devices, such as digital audio tape machines and compact disc players, which interconnect via digital audio signals. Use the mark you made in Step 9 to determine the correct spot for the hole. The hole should be fairly large and not hinder the movement of the pin.
