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.

Features

4-position Tape Select Switches allow kinds of tape, including the new Metal Tape, to be used

Full logic control of the two-motor tape mechanism

SEN-ALLOY heads for Rec/Playback and Erase. (An SA erase head with high erase efficiency is used so that Metal Tape can be erased)

IC-constructed ANRS (Automatic Noise Reduction System) and Super ANRS

With the REC MUTE switch, you leave silent passages between program material

5-point multi-peak level indicator

Timer standby capability for automatic start of recording or playback using an AC timer.

Remote control terminal (for the optional remote control unit R-30E)
