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.
#Studio 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. Professional digital audio equipment may have a word clock input or output to synchronize timing between multiple devices.
#Studio 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. 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.
