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.

Mark Levinson ML-2


ML-2 Monophonic Power Amplifier
ML-2 Class A power Amplifier in the appropriate system will produce striking sonic results. Each musical instrument is more articulated, while clear and open sound is maintained. Harshness seems to disappear from instruments with higher frequency content, such as violins. Music takes on more body and fullness. Absolute solidity of deep bass gives the entire performance an essential foundation and enables the listener to hear notes and passages that were previously inaudible. With quality recordings, the image of a performance is precise and remarkably stable appearing to emanate from a wider, taller and deeper stage.

The ML-2 may be operated in either the inverting or non-inverting mode. This allows a pair to be used in bridged configuration without additional circuitry. In bridged mode, two Ml-2s deliver twice the output voltage and four times the power. The power supply is fully regulated under all operating conditions. The ML-2 offers completely modular construction allowing efficient up-dating 9when available) and ease of servicing if required.
While outstanding performance can be achieved in high power amplifier designgs, the refined sound quality offered by ML-2s can only be attained by a design that, by today's standards, is limited in output voltage. The ML-2 is rated at 25 watts continuous sine wave power into 8 ohms from 20 Hz to 20 kHz with no more than 1% THD. For this reason, Ml-2s work best with higher efficiency loudspeakers, in multi-amp systems, or with lower efficiency speakers where loud listening levels are not required. While Ml-2s may not be optimum for every application, in the appropriate system they offer a beauty of musical sound unachievable by any other design.
