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.

Akai AA-1050

 The AA-1050 the top-of-the-line stereo receiver. Part of Akai's new 1000 series of Stereo and Quad components. We believe it's the finest line of receivers, for the money, in the business.
Like all our receivers, the AA-1050 was built with the same commitment to quality that made Akai tape equipment internationally famous.
We feel you won't find another receiver that comes on for the price with better sound or performance. Or better styling. Clean. Brushed aluminum. Beautiful. The strength of Akai. It's in our AA-1050. it's in our 1000 Series. With power output from 14 watts to 80 watts per channel, there's an Akai receiver for you. So you can make your own strong statement.
