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.

Pioneer PL-2 turntable


A poorly-engineered direct-drive turntable is inferior to a well-engineered belt-drive turntable - that's the axiom we have believed in and followed over the years. A prime example is the PL-2 belt-drive turntable. For its price and performance, it beats any competitive model, belt or direct driven, hands downs.
The belt-drive system of the PL-2 is an updated version that provides all the necessary torque and accurate speed control. A finely polished elastic belt is driven by a Pioneer DC motor. The motor assures smooth platter rotation, while the belt absorbsfinally all traces of vibration while powerfully transmitting motive power from the motor to the platter.
Where the PL-2 differs from the conventional belt-drive model is its Stable Hanging Rotor, a kind of cup fitted to the shaft under the platter. It gives the platter a stabilizing force that keeps the platter steady as it revolves, reducing potential platter wobble.

Giving the Pl-2 aa distinctive look is a straight low-mass PG tone arm. Since it is insensitive to resonance and hence to warps and eccentricities of records, it tracks even the most difficult-to-follow record grooves easily. The arm combines high tracking ability with high sensitivity to permit the use of any cartridge, whatever its compliance or operating principle.
Like all Pioneer turntables, the Coaxial Suspension system protects the arm, cartridge and records from acoustic feedback. And that's the reason why the Pl-2 boats a high Signal-to-Noise ratio of 68 dB.
The PL-2 is an auto-return model. At the end of play, the arm automatically returns to its rest and shuts the power off. Operaation couldn,t be simpler; There's just one control - for speed selection - on the slanted front edge of the turntable.
