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 SE-300

 Pioneer SE-300 High Polymer Stereo Headphones
The operating principle of the E-300 is completely different from that of conventional headphones; a high polymer piezoelectric material is used for the acoustic diaphragms. This has revolutionized the headphones.
 Features:
Distortion is extremely small even for low level sound, because the effective area of the acoustic plate is increased. This result is greatly improved frequency response compared to conventional headphones.
Large input handling capacity allows you to listen to higher level sounds than was ever before possible.
These headphones have higher efficiency than electrostatic and electret headphones; no special output other than the amplifier's headphone jack is necessary for connection
Operation is very stable in environments of different temperature and humidities.
