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.

Scott PS-18 turntable

Semi-Automatic Turntable
The Scott PS-18 is a belt-driven two-speeds semi-automatic record player complete with factory installed pickup. Overall performance and soun quality is about average for the price, though the system is sensitive to external shock and vibration. The motor starts when the tonearm is moved off its rest. At the end of play the tonearm recycles to the rest and the motor turns off. The tonearm has a micro-adjust counterweight that serves as an 0 - 4 gram VTF (vertical Tracking Force) adjustment calibrated in 0,5 gram increments. There is a calibrated anti-skate. The pickup rated for 1,5 to 3 grams VTF, is factory installed in a fixed headshell. The stylus overhang gauge is a reference mark on the shell which isn't sufficiently accurate for user-installed pickups. The tonearm rest has a positivie user-applied lock that prevents accidental displacement of the tonearm from its rest, which might result in stylus damage. The PS-18 we tested was from the first production run at the factory. Subsequent units are to be delivered with a universal headshell mount to give the user more flexibility in cartridge selection and easier installation.
