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.

Phase Linear 8000 turntable

Model 8000 Series Two Linear Motor Turntable

No other turntable can match the Phase 8000, because no other turntable has such advanced motors. You can't buy a quieter turntable. Or one with as low wow and flutter. Or one that tracks better.

The Phase 8000's tangential tracking tone arm keeps the stylus in perfect 90° tangent with the grooves. It's the same way the master disc was cut, so the motion of your stylus is identical to the cutterhead stylus. There's absolutely no tracking distortion. No crosstalk. No skating force that can actually re-cut your grooves.

 


New Linear Motor Eliminates Mechanical Linkage

Other manufacturers have tried to move tangential tone arms with worm gears. Belts. Rollers. All with the same sad result; Mechanical connections pass on the noise and vibration of the motor. The Phase 8000 solves this problem with an ingenious Linear Motor. The tone arm base is a permanently magnetized armature that glides along guide bars above electro-magnetic coils. The arm moves by direct induction - not mechanical connection. So there's virtually no noise. Inside the tonearm, an opto-electric detector cell senses the slightest tracking error, and instantly sends correcting signals to keep the arm on track.
