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.

Denon DTR-2000

 DTR-2000 is one of the first DAT (Digital Audio Tape)Recorder  created for consumer users . By incorporating the SCMS (Serial Copy Management System), it enables users to make as many direct, first-generation digital dubs of CD's and other digital program sources as they wish, while limiting the ability to make digital copies of copies.
It also features an advanced version of Denon's 20-bit Super-Linear D/A (digital-to-analog) converter, called the lambda SLC.  The DTR-2000 comes with full-function remote control and complements ita analog connectors with both optical and coaxial digital inputs and outputs. While a number of manufactures have adopted one form or another of 1-bit D/A conversion. Denon has chosen instead to remain with the eight-times-oversampling, 20-bit Lambda SLC system, originally developed for its top CD players. 
 The Lambda enhancement is designed to minimize the zero-crossing distortion that is characteristic of most multibit D/A converters. Non-linearity is reduced still further by very careful factory adjustment of the converter's  MSB (most-significant-bit) registers. At the other end of the process, ahigh-speed analog-to-digital converter is used to quantize analog input signals.

The transport mechanism inside the deck is similar to that of a miniature VCR and uses the same helical-scan principle. The high tape-to-head speed needed for mutimegahertz frequency response, is achieved with a pair of heads mounted in a rapidly rotating drum set at an angle to the longitudinal direction of the tape.
