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.

Fostex A-2 reel-to-reel

The A-2 is two track on quarter-inch tape, mastering machine. The standard of the industry. But with one added attraction. The A-2 has sync. Which means you can extend its usefulness. When you need to cut a high quality, low noise, low distortion master, ecord on the A-2 in its normal mode. But when you need to perform a little fixing up, or you want to do some added production (like adding a few ideas at the last minute), use the A-2's Sync mode. It's built-in to give you added performance flexibility for your dollar. Another way personal Multitrack fits the equipment to your needs. And your wallet.
The A-2 packs all the features and functions of our multitrack recorders into a rugged, relatively lightweight mastering machine. It includes LED indicators of peak transient overload in record or playback modes. The A-2 gives you the kind of quality needed to help you produce stereo masters that truly showcase your talent.
