The serial transfer of digital audio data was already standardised by the AES (Audio Engineer-

ing Society) in the mid-eighties and dictates as such a 64 bit basic word width per stereo sam-

ple. Irrespective of the original word width (e.g. 16 bit) 32 bit is to be transferred for each mono

sample. A WordClock Generator produces per stereo sample, a cycle whose frequency corre-

sponds exactly with the actual sample frequency. A SuperClock Generator transmits the signal

in a 256 times higher clock frequency (256 FS). The question of which clock is the most suited

one has been under frantic discussion for some time now, but one must keep in mind that a

SuperClock can be a maximum of over 24MHz (256 x  96KHz) and may distort other equipment

in the studio. In addition, modern digital equipment also features high-quality error correction

components by means of which any disadvantage of a slower WordClock can be compensated.

The connections can be made by means of ordinary coaxial 75 Ohm antenna cable, or alterna-

tively you can buy ready-made standard cables in the specialised music stores.  In particular

for use in the "gig scene" you are advised to use highly flexible and technically robust cables.
