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.

Harman/Kardon HK350i receiver

Although conservatively rated at 20 watts per channel into 8 ohms, the new Hk350i has the ability to develop great amounts of instantaneous power to handle peak loads. The result is an economical receiver that will outperform conventional receivers of the same power rating.

To ensure optimum separation and minimum distortion under all operating conditionas, the HK350i uses phase-locked loop circuitry in the tuner section. This system senses any phase error in the broadcast system and automatically makes the necessary corrections, providing better stereo separation and Total Harmonic Distortion levels than in conventionals tuners. The Hk350i also features our new stereo blend control that allows your speakers to sound their best even when they cannot be positioned perfectly.

The HK350i lso offers more convenience features than you'd expect from an economy receiver. Like LED signal strength meter, tpe monitor function, FM muting loudness contour, and accommodations for two pairs of speakers.

The Hk350i, although it's our lowest priced receiver, it gives you the ame advanced technology found only on the most expensive esoteric equipment.
