CONGRATULATIONS!

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.

The following items should accompany your IDAT44 in its shipping carton:

Power unit. (Wall Pack)
Product Manual.
A warranty registration card.
A production quality control checklist.

If any of the above are missing please contact your dealer or our service support group.

Getting 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.

Operation

INPUTS.The 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.
OUTPUTS. 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 audio preamp.
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 on again.
FRONT PANEL DISPLAY: There are three blue display indicators on the front panel of the IDAT44.
Power: This light is illuminated when the unit is switched on and properly powered up.
DMPH: 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.
C-Lock™: When the incoming data stream has been locked to the IDAT44's internal jitter reduction circuitry the C-lock™ indicator will illuminate.
