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.

Phase Linear Model 200


 The Phase Linear Model 200 Stereo Amplifier is the best amplifier you can purchase for medium power handling applications. At 105 watts per channel, the 200 complements all high quality bookshelf speakers in the efficient to medium efficiency range. The 200 has enough power to eliminate clipping with most efficient speaker system as well as many inefficient systems
The Phase 200 has a Velocity Feedback switch which allows for a Reduction in current feedback. This results in a lowering of the damping ratio and this has been a recommendation made by various speaker manufacturers. In numerous speaker systems this reduction in feedback will provide a warmer, more mellow sound.
