The DDD-603 meter is capable of reading both AES/EBU and S/PDIF signals. Two
XLR connectors on the back of the unit are wired according to AES/EBU specs and
an adaptor described below should be used for S/PDIF signals. The meter input is
high impedance with minimal effect on the clock jitter. We found this type of in/out
superior to a regular 110 Ohm buffered in/out. In most situations the meter can be
daisy-chained, but in jitter critical applications (such as DAC inputs) it should be
connected at the end of the signal chain. The DDD-603 input/output is wired as
below:
The DDD-603 meter requires reg5V supply with min. of 1.5A capacity.
Every meter is supplied with such a power adaptor. Using different power supply
may
damage the unit and voids warranty.

Additional features
and software versions:
"Basic" version V1.3
"Full mastering" version V3.3
The DDD-603 meter is software based. Mytek manufacures two versions of the
meter: "basic" - V1.3 and "full mastering" - V3.3. The features described previously
are "basic" features. "Full mastering" softvare V3.3
provides extra features which can be enabled by setting the DIP switch on the back
panel of the unit. The switch works only if software version V3.3 or higher is
installed (it is disabled in the "basic" version V1.3). Version V3.3 has also a
function selectable at the front panel. For additional cost owners of the
"basic" version can upgrade to "full" version by exchanging the internal custom
memory chip at your dealer or Mytek.
