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.

Nakamichi CR-7A

The CR-7A from Nakamichi is a direct drive, three-head cassette deck with Dolby B and Dolby C noise reduction. The deck features manual playback azimuth tuning, asymmetrical dual-capstan transport, auto calibration of azimuth, level and bias andwireless remote control. The display shows remaining time elapsed time, or a four-digit counter reading in all transport modes including fast-forward and rewind. Other features include auto repeat, memoty stop, timer recording/playback, and a two-speed master fader control.

Escape from the ordinary.

Escape to the realism of Nakamichi sound.

The Nakamichi CR-7A Discrete-Head Cassette Deck - the most convenient - and sophisticated - recording instrument conceived by man. It selects equalization automatically - yet you can override the choice. It adjusts azimuth, level and bias automatically - yet you can match azimuth to any tape - from your armchair - with a wirless remote control. Its real-time counter readselapsedtime and time remaining. It will even fade out a recording just before the end - if you'd like.
