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.

McIntosh MC 1000 Mono Power Amp

McIntosh Is thought by many to have invented the high fidelity audio amplifier in 1949. And, through continuous research, McIntosh has been reinventing it ever since with new developments and refinements that bring us ever closer to the goal of absolute perfection in musical reproduction. This proven amplifier technology, together with a number of technical innovations, has resulted in audio amplifiers that are capable of meeting the challenge of moder performance requirements.

McIntosh power output wattmeters indicate the true power that the amplifier delivers to the loudspeakers, regardless of speaker loads or impedance variations. Driven by circuitry that constantly measures both voltage and current, these illumniated, peak responding meters are extremely acurate, responding to 95% of full scale with only one cucle of a 2,000 Hz tone burst.
Power Guard a patented McIntosh circuit design , eliminates harsh clipping distortion without sonic side effects Not a “soft clipping” circuit or a limiter, Power Guard has no effect prior to the clipping point of the amplifier. A waveform comparison circuit continuosly monitors, the output signal and compares it to the input signal. Should distortion appear in the output signal, Power Guard acts by reducing the level of the input signal until distortion is reduced below clipping then restores the amplifier to full gain. because it is so brief, only thousandths of a second, you won’t hear the gain reduction. power Guard assures your listening pleasure and protects your loudspeakers from the damaging effects of clipping distortion.

McIntosh has provided their unique output autoformers in all of their “flagship” power amplifiers since the beginning of the “solid state” era. McIntosh output autoformers enhance amplifier performance by providing optimum loading of the output devices. This assures that maximum current may be delivered by the output circuit without exceeding the safe limits of the output devices. Additionally, autoformers provide expanded operational flexibility and contribute to long, consistent performance with far greater reliability.
