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.

Besides raising and lowering of amplifier volume, the remote transmitter can be used to switch modes from Tuner to Tape, Aux to Phono, etc. Another remote function sure to come in handy at times is the -20 dB muting facility.
