About Wordclock

Digital audio equipment must be synchronized when

digital audio signals are transferred from one device to

another. Even if both devices use identical sampling

rates, digital signals may not transfer correctly, or audi-

ble noise or unwanted clicks may occur if the digital

audio processing circuits inside each digital audio

device are not synchronized with each other.

Wordclocks are signals that enable digital audio pro-

cessing circuits to synchronize with each other. In a

typical digital audio system, one device operates as the

wordclock master, transmitting wordclock signals, and

the other devices operate as wordclock slaves, synchro-

nizing to the wordclock master.

If you are digitally connecting the 01V96i to other

equipment, you must decide which device to use as the

wordclock master and which devices to use as slaves,

then set up all the devices accordingly. The 01V96i can

be used as the wordclock master running at either

44.1kHz, 48 kHz, 88.2 kHz, or 96 kHz, or slaved to an

external wordclock source.

Wordclock Connections

To establish wordclock synchronization between the

01V96i and external devices, you can distribute word-

clock signals independently via dedicated cables, or you

can use clock information derived from digital audio

connections.

The WORD CLOCK IN and OUT connectors transmit

and receive wordclock signals independently on the

01V96i. The following examples show two ways in

which wordclock signals can be distributed and received

via the WORD CLOCK IN and OUT connectors.

Daisy Chain Distribution

In this example, the wordclock si gnal is distributed

in a “daisy-chain” fashion, with each device feeding

the wordclock signal from the wordclock out con-

nector on to the wordclock in connector of the next

device. This method of distribution is not recom-

mended for larger systems.

Star Distribution

In this example, a dedicated wordclock distribution

box is used to supply wordclock signals from the

wordclock master to each wordclock slave individ-

ually.

If the external devices do not have wordclock in and

out connectors, you can use the clock information

included in the digital audio signals. In this case,

digital audio signals and wordclock signals are

transferred via the 2TR OUT DIGITAL and 2TR IN

DIGITAL jacks or via the digital I/O card installed

in the rear panel slot.
