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.

Krell FPB-200C power amplifier


Power is a vital key to accurate sound reproduction. But power alone provides but a translucent window; it often dulls our aural perception. For true transparency - the exciting immediacy that conveys both the shudder and the shimmer of today's best sources - power and finesse must go hand in hand.
The FPB amplifiers respond to this challenge with a unique and potent array of highly refined technologies. True balanced signal paths from input to output guarantee virtual immunity from noise  as theyenhance speaker control. Class A operation provides sound gloriously free of switching transients while the Krell patented Sustained Plateau Bias II circuitry avoids the heat and inefficiencies of less sophisticated implementations. CAST, a radical and illuminative revision of the system-amplifier interface, eliminates cable variations that can adversely affect sound.
Thus, every amplifier in the FPB Series provides absolute and unwevering control.
