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.

Audiolab 8000C Pre-amplifier

The Audiolab 8000C pre-amplifier is a highly versatile control pre-amplifier..It offers the flexibility of tone controls, built in class A headphone amplifier and loe output impedence line amplifier. It has inputs for CD, phono, tuner, video, tape 1 and tape 2. The phono inputs match all types of modern Moving Coil and Moving Magnes cartridges. The low output impedance line amplifier is a miniature class A power amplifier with current mirror bias. Perfect for long cables and multiple power amplifiers That is especially important if you want to place your power amplifiers (e.g. 8000M's) close to the loudspeakers.
