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-540 amplifier

PMA-540 Direct A, Real Drive Circuit - Integrated Amplifier

Non-switching power amplifier delivers 60 W + 60 W power output

Super equalizer amplifier provides a wide RIAA deviation from 20 Hz - 100 kHz ±0,2 dB

Real drive circuit reduces distortion during speaker drive by 1/50

Newly developed real time tone control circuit prevents deterioration in sound quality

Provided with A, B speaker system for individual On Off switch.
