ADAT Interface (with S/MUX ™)
ADAT MDM interface is equipped with two ADAT ports, A an B which allow to operate
with either one or two ADAT MDM machines or interface to other ADAT compatible
equipment for up to 8 channels of I/O and signals up to 24/96. ADAT interface uses
clock embedded in the optical signal and no wordclock is required to operate the interface
although it can be used when appropriate.
The diagrams below illustrate most popular system applications. We recommend one
tailored to your equipment and needs. Because of sample accurate operation of ADAT
MDMs several 8X96 units can be stacked to increase number of channels. In this case the
first ADC is usually the clock master while the rest are clock slaves.
Detailed description of dip-switch functions can be found in chapter “dip-switch
settings”). Not all possible setup configurations are mentioned (such as e.g. 16 bit/96 k)
48 or 96 numbers are used as an abbreviation. They mean 44.1 kHz and 48 kHz OR 88.2
kHz and 96 kHz sampling frequency.
Users of 20 bit ADAT MDMs, ADAT interface equipped harddisk recorders and certain
ADAT interface equipped computer cards (Hammerfall, Sonorus Studi/o) can take
advantage of 96kHz capability of Mytek ADAT interface which is achieved by
employing sample splitting technique known as Sonorus S/MUX (tm). S/MUX ™ sample
splitting has been design to allow 96k operation using standard 48k ADAT interface
transmission, where one high speed 96k channel is split between 2 48k channels (tracks).
This technique is compatible with dual wire AES, Prism Sound Split96 (tm) and
recording technique used in Tascam DA98HR. In other words 96k tapes recorded on
DA78HR using Mytek 8X96 can be played back on DA98HR without the need of any
decoder. Read more in chapter “S/MUX”
For these concerned with 20 vs. 24 bit sound quality, we’d like to assure you, that signal
recorded at 20 bit using sophisticated SupershaperHR ™ is virtually indistinguishable
with 24 bit. As a matter of fact we challenge anybody who can distinguish these two
settings, especially at 96kHz. We can safely say that 20 bit 96k masters produced with
Mytek 8X96 will outperform most of other 24/96 masters produced with different
equipment.
