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.

Aiwa AD-F880

 Superior 3-Head Fidelity with Advanced Features
The AD-F880 is a quality 3-head deck with a variety of advanced features for superb high fidelity performance.
The 3-head design incorporates AIWA's super DX recording and playback heads which feature cores are wound with PC-OCC (Pure Copper-Ohno Continuous Casting) copper wire having ultra high conductivity for greater musical resolution.
The die-cast alloy Bias Shield Head Block minimizes interfrence between the recording and playback heads.
 AIWA's original micro-grain surfaced dual capstan drive improves tape transport performance, while the ATMS (anti-modulation tape stabilizer) damps out resonance for clearer sound reproduction.  The manual recording calibration system and bias fine adjustor allow optimum recording performance with any tape formulation you use.  Dolby B and C noise reduction systems work to reduce unwanted tape hiss, while Dolby HX professional circuitry works during recording to extend high frequency response with any type tape.
Convenience extras like wireless remote control, feather-touch IC logic controls, an electronic tape counter with memory rewind and repeat, and more make the Ad-F880 the kind of deck you can depend on for quality cassette performance.
