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 DR-750


Denon DR-750 Stereo Cassette Tape Deck
Denon has researched on better tonal quality through a tape transport mechanism, the head, and the amplifier to design the DR-750 cassette tape deck. The tonal quality depends on the characteristics and the construction of the tape transport mechanism and the head. Recording and playback head consist of unique Sendust tip developed by Denon, so that it records with a wider dynamic range together with a superior recording linearity and the lowest distortion at a high level. Combined with the Denon high quality head, model DR-750 achieved an excellent tonal quality and the performance of tape transport which is superior to a 3-head system.
