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.

Pioneer CT-F 7272

Front-Access Stereo Cassette Deck with Pioneer-Exclusive Automatic Chrome Detection, Vertical Cassette Hold, Dolby, Memory Stop and Other Advanced Features.
The Pioneer CT-F7272 isn't the most elaborate nor expensive deck on the market. But it has a number of exclusive features that add up to the kind of handling convenience and musical quality that aren't normally found in its price range. Among them is the Pioneer-perfected Automatic Chrome Detection System to eliminate the guesswork when you use wide-range Chrome tapes. It switches the Bias/Equalization to the correct values for Chrome, and also makes it easy to take advantage of the newer Ferrichrome as well as standard low-noise tapes. Advanced features like the Pioneer-exclusive Vertical-Hold Cassette Compartment help you realize the full potential of the space-saving front-loading format.

Tapes are held firmly upright so you can read labels and see tape movement. All controls are up front for quick access. They include those for Dolby, Memory Stop and the easy-touch pause and tape-transport keys. Big, accurate Vus twin Chrome/ferrichrome indicator s, LEDs for Rec and Dolby modes and separate controls for input and output improve handling ease.  Inside there's a wide-dynamic -range preamp plus a precision DC tape drive system with low wow/flutter, a tough Ferrite-Solid head, a built-in MPX noise filter for recording FM stereo , and more. The Pioneer CT-F7272  is guaranteed by Pioneer to bring you the convenience and quality you can't beat in its price range.
