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.

Yamaha K-960 (1981)

when yamaha's audio engineers decided to design a truly high performance cassette deck, they didn't overlock any details. First, they chose a two-motor transport, but redesigned the system to eliminate the instabilities of conventional two-motor designs. For the Rec/Playback head, they used the finest material available - Sendust - formed by a unique Yamaha process for absolute purity. With 5-layer core lamination and low impedance design, this head is superior to ordinary types in all respects. And for the best possible dynamic range and signal-to-noise ratio, the dbx system was included.
Add to this features like fine bias adjust, focus switch, metal compatibility and Dolby NR, and the result is the K-960 - a triumph of cassette deck engineering.

Frequency response: 40 - 22,000 Hz (metal tape)
S/N ratio: 100/60 dB (dbx on/off, metal tape)
Wow and flutter: 0,028%
Input sensibility: 50 mV
Input impedance: 100 kohms
Output sensibility: 340 mV
Dimensions (W x H x D): 435 x 141 x 304 mm
Weight: 8 kg
