What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

McIntosh MDA 1000

Hear all there is to hear from your existing CD collection. Let the MDA1000 modify your music data stream from 16 bits to 24 bits, and to a sampling rate of 768kHz all while still in the digital domain. Then the MDA1000’s eight, 24 bit Burr Brown digital converter take things from there. This processing allows such gentile filtering to the converted signal that the original musicality comes through, instead of the sound of the digital circuits themselves. The difference is easily heard. Listen and you will be amazed at how older discs rival, or often exceed, the sound of the new “higher resolution format” discs.

The MDA1000 D/A Converter and its matching MCD1000 CD Transport represent the introduction of a new and elite product category from McIntosh. The philosophy behind this enhanced level of McIntosh products is nothing but the best…to deliver the absolute highest possible performance without design constraints. Available only through McIntosh Authorized Premier Dealers, the MDA1000 and the MCD1000 are merely the beginning of this exclusive line.

Seven Digital Inputs

3 Coaxial Inputs on RCA Jacks

3 Optical Inputs

1 Balanced Digital in on XLR Jack

Balanced (XLR) Outputs

Unbalanced (RCA) Analog Outputs

Front Panel Volume Control with

Optional Bypass Function

3D Glass Front Panel

Fiber Optic Lighting

Remote Control

POWER SUPPLY

Multiple layers of regulation provide clean power to all critical circuits. The power transformer has the lowest noise field of any available.

CIRCUIT SHIELDS

Each D to A Converter is shielded to avoid any chance of hum or noise getting through.

VOLUME CONTROL

Precision front panel and remote volume control allow the MDA1000 to function as a preamplifier in an all-digital system. Setup programming allows volume control bypass if desired.

FRONT PANEL DESIGN

3D front panel glass design is illuminated with long-life, cool-running fiber optics that make operation in low light easier. Silk screening on the inside of the glass front panel prevents wear of the nomenclature, ensuring lasting beauty and highest resale value…a McIntosh hallmark feature.
