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 250

 Marantz Model 250 Professional Stereo Power Amplifier
250 Watts of contiuous power may be more than enough for you own homemade jam session. Because the Model 250 offers the kind of brute strength you need for vibrant, professional stereo sound in a variety of  uses, such as studio monitoring, sound reinforcement and custom stereo applications. Although it's rated at 250 Watts RMS (125/channel), under typical use this Marantz amplifier delivers up to 300 Watts of power into 8 ohms, from 20 Hz to 20 kHz, with less than .05% THD and IM distortion. An added feature for the pro is the illuminated output level meters with Power Range Switching. These meters work as visual indicators, showing actual power output to speakers. With them, speaker overload and/or overdriving amp inputs can be checked and, consequently, avoided. Power, features, price. And the nicest thing about the 250 is that you don't have to compromise one for another.
