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.

Sony TC-K65

The Sony TC-K65 shares much in common with the TC-K61. Both decks incorporate Sony's smooth, two-motor and high-torque spooling motor. Both machines have the Sendust and Ferrite record/playback head for superior dynamic range and low distortion. And the K65 has the same microprocessor logic function sequencing and the same LED Peak program Meters as theK61. What distinguishes the K65 are two important operating modes: mic/line mixing in record, and Sony's extraordinary Random Music Sensor (RMS) in playback. With these features, the K65 achieves a new level of versatility and convenience.

Mic/Line Mixing
For recording flexibility the microphone and line-level inputs of the K65 can be mixed. Thus, you can record simultaneous music and narration, or add your own musical material to recordings of broadcasts and discs. The K65 facilitates input mixing with independent level controls for left and right "mic" and line inputs, along with a convenient master record level control.

Random Music Sensor
The TC-K65 incorporates Sony's RMS (Random Music Sensor) a system that can be programmed to automatically locate and play individual selections of music. Working in conjunction with the transport microprocessor, the RMS allows you to hear a cassette's musical selections in any sequence you choose. For example, you can listen to the third selection, and then the ninth and the second automatically.   You enter the desired sequence into the RMS using the "program" and "memory" buttons. With RMS, the deck automatically fast-forwards or rewinds locates the selection and plays. The numersal display glows to indicate each selection, RMS can distinguih up to fifteen selections on a single cassette side. ANd you can program up to sixteen instructions, including selection replays.
 You can also take advantage of the RMS without programming, RMS provides the ability to "skip" back to the beginning of a selection or "skip" forward to the beginning of the next selection.
These responsive functions of the RMS, along with AUto Play, Memory Stop and Memory Play timer operation and remote control capability make the Sony TC-K65 exceptionally convenient and effortless to use. With the K65, it is easier than ever before to hear exactly the music you want to year, exactly when you want to hear it.
