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.

Mitsubishi DT-10 cassette tape deck

Advanced Features and Superior Performance
The DT-10 offers both excellent basic performance and great ease in use combined with the attractive lines of the whole Mitsubishi Audio Component line0up. Ultralow wow and flutter - only 0,06% WRMS; are ensured by the use of a DC servomotor with large (2-7/8") flywheel, a capstan circular to within a 0,3 µ tolerance, and a high precision drive assembly.
Special circuitry and selected components help to realize the full advantages of Dolby noise reduction. Mitsubishi's own ultralow-noise PNP-type epitaxial transistors are used in the first stage of the recording equalizer amplifier.

Residual tape meter
The DT-10 has a special meter to tell you how much time is left before the tape will end. Often useful during playback, it is an invaluable aid to high quality home recording.

Recording Master Volume Control and Mixing Facilities
Like the DT-30 , the DT-10 has separate level controls for Mic and Line inputs, so that both can be mixed, and a master recording level control for professional-type fade-in and fade-out effects.

Other Features and Functions
