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.

Luxman K-117

 High Capability Dolby / Metal Cassette Deck

The Luxman K-117 cassette deck incorporates the most modern and desirable features of contemporary cassette deck design. In keeping with the long-standing Luxman reputation in tape deck technology, it affords the discriminating listener accurate sound reproduction that's true to the music.
The K-117 is fully compatible with metal particle tapes, and it has been thoroughly engineered to make full use of their extended high frequency response and wider dynamic range. It also accepts chromium and normal bias tapes and features Dolby circuitry.
The K-117 also offers some unique features of its own.
 A bias Fine Control, operated from the front panel, lets you alter bias current within ±15% from the nominal (average) bias point. In effect, it gives you the freedom to subtly alter the frequency response for any given tape.
Instead of VU meters, the K-117 utilizes a fluorescent peak level indicator for quick response to the recorded signal. To help you handle the extended dynamic range of metal tapes, the indicator has provisions for an additional 3 dB of level which becomes up to +8 dB.
Tape movement is activated by logic/solenoid feather-touch controls, for which an optional remote control box is available. An auto-repeat function automatically rewinds the tape at its end and repeats play.
Of course, it's the sound of the Luxman K-117 that really counts. And that's how it sounds. Like a Luxman. Free of audible distortion, full range, and accurate.
