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.

 The wrong cassette deck will play your tapes to death. Just a fractional misalignment of all those pulleys, belts and wheels, and you wind up with tapes that are more of a pain than a pleasure to listen to. That's why we took such care with the tape transport in our new TC-520.
The only directly power driven part, for instance, is the capstan. So there's less chance your tapes will feel stretched.
We've made sure that this crucial capstan is rounded to within 0,1 microns of perfection. So everything turns the smoothest possible circle. There's double belt drive for even more stable rotation.
While the DC motor is designed to give high torque and low vibration. Very smooth.
Just as smooth as all the other features.
Yamaha's superhard permalloy head means clean sound with less wear. You have the choice of low noise, chrome and ferrichrome positions. A bias adjust selector means you can choose the perfecct setting for each individual tape. While two illuminated VU's flash red for +8 dB, yellow for +3 dB.
Yamaha high performance means you can always expect pur natural sound with low distortion. So you'll never hear anything except what you want to hear on our new TC-520.
