You are now the
proud owner of one of the finest D/A converters ever built. The IDAT44 is
the digital-to-audio converter which culminates over eight years of effort by
Ed Meitner and his design team.
The result is a world-class digital audio system for the home. In the course
of our continuing research, attention has been devoted to every detail of the
digital-to-analog conversion path.
The innovative engineering behind this award-winning product has achieved recognition
in the form of several patents and through a technical paper presented to the
Audio Engineering Society.
following items should accompany your IDAT44 in its shipping carton:
- Power unit.
- Product Manual.
- A warranty registration
- A production
quality control checklist.
If any of the above
are missing please contact your dealer or our service support group.
To Know Your IDAT44
Some IDAT History
- In January,
1993, the Meitner IDAT (Intelligent Digital Audio Translator) was introduced
to the audio market with a price tag hovering around 15,000 dollars. It met
with rave reviews around the world. The IDAT was described as perhaps
the most technically sophisticated consumer audio product ever produced.
- At the same
time as IDATs were being produced, Museatex was launching a project that would
incorporate the IDAT algorithm and design features into a product that
would target a wider market at affordable prices. The key issue was to accomplish
this without sacrificing the ground-breaking performance of the IDAT.
- The results
were astonishing. The IDAT44 not only met the critical performance
specifications of the IDAT, but bettered them in several ways.
- The IDAT44
translates the stream of "ones" and "zeros" from your
CD deck to an analog signal compatible with your existing hi-fi system.
- It does this
better than existing D/A converters, especially the ones built into CD players.
- The power supply
electronics switch at a rate synchronized precisely to the sample frequency
of the recorded data. C-lock(TM), a proprietary jitter reduction technique,
is utilized to drastically reduce phase jitter in the digital bit stream.
Phase jitter is a cause of the "harshness" and "graininess"
in audio reproduced from digital sources.
75-ohm coax and fiber-optic TOSlink inputs on the rear of the IDAT44 allow
it to be connected with all standard digital audio sources operating at a
44.1 KHz sample rate. (This is the sample rate used by the Compact Disc.)
- INPUT SELECT
SWITCH.A slide switch on the rear panel allows selection of either a coaxial
or a fiber-optic input.
The analog outputs are two color-coded RCA connectors. The left channel is
white and the right channel is red. The IDAT44 outputs can drive any
- POWER SWITCH.
A slide switch on the IDAT44 rear panel allows you to switch the unit
on and off. If you prefer, you can leave the IDAT44 on at all times,
since it consumes very little power.
- RESET BUTTON
The IDAT44 , like most electrical units, can be disrupted by large
charges of static electricity. The reset button forces a hardware reset to
the DSP processors and re-initializes the IDAT44. Should the operation
of the unit be disrupted by static electricity or a power line disturbance,
press the reset button (RST) on the back of the unit. If it is more convenient,
the IDAT44 may be reset by switching the power off for a moment, then
- FRONT PANEL
DISPLAY: There are three blue display indicators on the front panel of
This light is illuminated when the unit is switched on and properly powered
The DMPH (De-emphasis) indicator comes on whenever De-emphasis is being applied
to the incoming data stream. De-emphasis is required for CD's that have been
recorded with frequency pre-emphasis.
When the incoming data stream has been locked to the IDAT44's internal
jitter reduction circuitry the C-lock indicator will illuminate.
