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.

EISA 2012-2013 Audiolab M-DAC

 The new age of USB computer audio has rekindled the flame of the outboard D/A converter (DAC). Among this new breed of USB DACs few are as simple to implement or as versatile in use as Audiolab’s fabulous little M-DAC. It works directly with virtually all PCs and Macs without special USB drivers while its bold display shows a wealth of information about the incoming music data. An onboard volume control lets the M-DAC do the job of a preamp just as the choice of seven digital filters allows fine-tuning of its sound. And what a sound – powerful, insightful and delicate, it cuts to the heart of the music while remaining faithful to its soul. This is a very high performance product that’s perfect for both the computer audio novice and seasoned enthusiast alike.
