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 240

 Marantz Model 240 Basic Stereo Amplifier
Not just another pretty face, the Model 240 offers the same reliable power, the same craftsmanship and endurance as the Marantz 250. what it doesn't offer is the two front panel meters. With this model you get all the same high-performance features - but you don't get the meters to tell you about them. You get the Variable Overlap Drive, which automatically compensates for natural aging of components, giving continual "like new" performance. And the Model 240 offers complete stability regardless of load, massive heat sinks and more. 250 Watts continuous power into 8 ohms speakers, (typically 300) from 20 Hz to 20 kHz with total harmonic and intermodulation distortion under 0,1%. So, far the identical Marantz quality you're saving yourself some money. When you're thinking about buying a stereo power amplifier, think of the Model 240 as the one that's made to listen to - not look at.
