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.

Kenwood KW-5066

 4 head Sosslid State Streo Tape Deck
Kenwood's KW-5066 is equipped with epoch-making Recording Bias Adjustment, high Speed full Track Erase System, Sound-on-Sound and Echo Recordings with Level Control etc., which will no doubt recall the real pleasures of Recording most tape decks have been long passed by.  Its recording and reproduction quality is needless to say refined by low noise pre-amplifiers. Add on your line-up and fully make use of  this Super Recording machine, KW-5066.

Special Features
Recording Bias Adjustment System permits the most desiderable bias for high fidelity recording on the recorder for a specific tape by the incorporated test signal oscillator.
 The exclusive Full Track Erase head with triple safety mechanism for rewinding provides instant full track erase of a pre-recorded tape.
 Easy-to read large size dual illuminated VU meters on the front panel ensures accurate recording and playback levels.
 Separate Input and Output level Control for easy monitoring.
 The exclusive DIN connector permits easy dubbing.
 Easy loading by one hand.
Sophisticated special recording can be done by setting only Sound-on -Sound and Echo recording level control and switch on front panel.
 Auto-Stop mechanism built into the head housing and 4-digit tape counter.
 Low-noise Silicon Transistors are used in special record and playback pre-amplifiers for high signal-to-noise ratio and low distortion.
 A Tape  Monitor Switch enables a fast, easy means to check sound immediately before and after it is recorded during the recording process.
 Three tape speeds to suit your recording requirements - 71/2 ips and 33-/4 ips speeds for high fidelity recordings and 1-7/8 ips for speech recordings
Noise Filter enables one to eliminate undesirable hiss noise on pre-recorded tape.
