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.

Marantz Model 19


 This is simply the most expensively designed stereo receiver in the world. The Model Nineteen offers more for your money than any other receiver made today. By talking the finest FM stereo tuner, the most sophisticated of stereo preamplifiers, plus high-performance power amplifier - and blending them all into one precision machine… the Marantz Model 19 is a study in excellence. Here's why.
 

 The Model 19 offers 100 Watts of continuous power into 8 Ohm speaker from 20 Hz to 20 kHz. And total harmonic and intermodulation distortion is less than 0,15Z% with ± 0,25 dB frequency response. The built-in oscilloscope is a visual indicator that shows the finest tuning adjustment for perfect reception, even on the weakest stations. Also, the Marantz exclusive Gyro-Touch tuning wheel reduces friction and wear and asures optimum tuning accuracy. And there's the Variable Overlap Drive. This automatically compensates for natural aging of components, making each listening experience an openng night performance. Now, put all these exciting features behind a gold-anodized front panel with etched black lettering and frame it in sleek, hand-rubbed walnut cabinetry. And you have the Model 19 .
