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.

Marantz Model 2230


 MARANTZ MODEL 2230 AM/FM STEREO RECEIVER
With impressive specifications and Marantz-exclusive features, the low-prieced Model 2230 offers more value and performance than any other receiver in its class. It delivers 60 watts continuous RMS into 8 ohm speakers from 40 Hz to 20 kHz with total harmonic and intermodulation distortion under 0,5%. Frequency response is ±0,5 dB. Stepped, three-zone controls for Bass, Mid, Treble. Provisions for tape decks, phones, record changers, 4-channel adaptors. Ultra low-distortion FET, RF and IF circuitry. Massive heat sinks; automatic protection for internal circuitry and associated speakers, plus the famous Marantz gold-anodized front panel. Completely enclosed metal chassis finished in simulated walnut or with optional WC-22 walnut cabinet.
