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.

Onkyo M-5000R

Thrill to the Visceral Power of Stereo
Music, when you hear it in all its glory, has the power to lift the spirits and transport you into another realm. Driving you there in audiophile style is Onkyo’s newest hi-fi power amplifier, the M-5000R. Signal quality on the M-5000R is meticulously preserved by new AWRAT technology, while three-stage inverted Darlington circuitry provides extremely efficient power output. Massive twin toroidal transformers and four 27,000 µF capacitors work to stabilize the power supply and current, respectively. And to minimize errors in stereophonic playback, the amplifier incorporates a totally symmetrical alignment of power devices for left and right channels.
