What is a word clock used for?
Word clock is used by the receiving digital device to lock to the incoming digital signal. Every digital device, from a simple, portable CD player to a Pro Tools HD rig, has a word clock. Not to be confused with sync clock (like MTC or SMPTE), word clock is what tells an A/D or D/A converter when to begin each sample.
What does word clock embedded mean?
Word Clock is a timing reference for digital audio devices. … Word Clock provides a measurement of the passing of time at the speed of the sample rate. It allows multiple digital audio devices to synchronise with one another. Word clock may be embedded in a digital audio signal or generated and transmitted separately.
Do I need a word clock cable?
The clock provides the timing information and lets the digital signal be converted back into analog at the exact time it needs to be. … Every piece of audio equipment has internal clocking, but if you want to use multiple devices, you need digital cables such as BNC, ADAT, or S/PDIF to synchronize them together.
Is word clock analog or digital?
The word clock signal doesn’t contain any other data. This allows it to do one job, and do it well. Many modern audio devices, such as analog-to-digital converters, have built-in word clock generators. In this article, we’ll focus on a couple of devices where the sole purpose is clock signal generation.

Do I need a clock for my studio?
In most compact project studios, there’s little need for a master clock. The required system clocking can usually be achieved by interconnecting the equipment directly and, as explained above, where there’s only one A‑D in the system, it’s generally best to use that as the clock master anyway.
What is master clock audio?
The master clock is controlling the rhythm of the CD player by telling the DAC chip exactly when to convert the audio signal from digital to analog. To have the best possible sound, it is vital to have a master clock that has a very stable clock frequency and lowest possible jitter.
What is master clock generator?
The master clock generator is an extremely stable oscillator that supplies external clocks to digital devices (such as a transport, D/A convertor, Super Audio CD player) equipped with clock input terminals.
Can you daisy chain word clock?
So most clock generator manufacturers strongly advise that you not daisy chain using the in-to-out connectors on your audio devices. One tech rep put it this way: “Every (passive) daisy chaining of clock lines degrades the quality of your clock signals regarding their jitter performance and voltage level.”
How are signals clocked?
We can define a clock signal as a particular type of signal that oscillates between a high and a low state. The signal acts like a metronome, which the digital circuit follows in time to coordinate its sequence of actions.
What is a BNC word clock?
The word clock is a square wave signal that is transmitted via a 75Ω BNC connector. A square wave, of course, alternates between high and low states, which makes it ideal as a timing references. … Most professional digital audio devices have a word clock input so they can work in sync with other devices in the studio.
Can ADAT carry word clock?
By contrast, AES3, S/PDIF and ADAT all embed the clock pulses within the audio stream by using a type of modulation process.
Does AES need word clock?
S/PDIF, AES/EBU, ADAT, and TDIF are some of the formats that use a word clock. … The device which generates the word clock is the only master clock source for all the slave audio devices.
What cable do I need for word clock?
A word clock signal is typically a 0 to 5V square wave at the digital audio sampling rate. The word clock jacks use standard 75 ohm BNC connectors, and standard 75 ohm coaxial cable should be used (coaxial television cable, not shielded mic cable).
