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 2010

 Marantz Model 2010 AM/FM Stereo Receiver
The newest addition to the Marantz line of stereophonic receivers is the compact Model 2010. Here's proof that marantz can make a comparably priced receiver without compromising traditional marantz styling and quality. The Model 2010 is a full 20 Watts continuous power into 8 Ω speakers, from 40 Hz to 20 kHz, with THD and Intermodulation under 1,0%. This system combines all Marantz high-performance features into a smaller body, sized to fit any shelf or  table. Complete with tape, phono and auxiliary inputs as well as quick-connect output terminals fro main and remote speakers.  This precision-constructed unit also offers Gyro-Touch tuning for accurate reception; plus FM muting pushswitch, which eliminates inter-station noise when tuning. With built-in ferrite AM antenna and advanced soild-state circuitry throughout, the Model 2010 is the finest piece of stereophonic equipment in this price range.
