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.

Denon PMA-510 amplifier

High c/p Direct A - Pre-mai amplifier

Highly efficient non-switching power amplifier delivers large output power of 50 W per chqannel.

Super equalizer amp and non-switching power amp. 2-stage pre-main amp equipped with direct DC servo circuit substantially imoroves S?N while reducing distortion. Super equalizer amplifier offers surprisingly wide range of reproduction.
