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.

 This dependable auto-return belt-drive turntable offers the multiple benefis of precision and convenience. Its uncomlicated mechanism permits the stylus to track freely, as on any first-class manual, until the stylus enters the lead-out grooves to the record, or until you trigger the Reject control. All controls are grouped at the right side to enhance ease of operation.

Dependable Auto-Return/Shut-Off Operation
No-Rumble Belt-Drive
JVC 4-Pole Synchronous Motor
Practical performance at a  pleasing price
 Dependable, Belt-Drive System
A 4-pole synchronous motor and belt drive system are employed in this unit for silent and reliable operation. The nonferrous die-cast platter of the JL-A20 is spun precisely for more critical operation. This motor maintains very close tolerance speed accuracy regardless of changes in loads or power voltages.

Th and Anti-Skate Device
The tonearm features JVC's TH (Tracking Hold) system to avoid mistracking, distortion, channel imbalance and undue record wear. The anti-skate device is of  the easy-to-use knob type that lets you apply the required anti-skate force even while the arm is tracking a record. Record and stylus wear is thus reduced. Like the JL-F30, this model features the low-silhouette look abd gets you closer than you've ever been to The Musical Truth,
 Auto-Return/Shut-Off Convenience
Place the stylus on the first groove of your favorite record, then sit back and enjoy the music - leaving the rest to the automatic mechanism of this unit which sends the arm to its rest and turns off the power at the end of a record. You operate the reject lever to interrupt play and send the arm backto rest. And the oil-damped Cue lever lets you menually place the stylus on the groove of all your favorite selections, regardless of the arranged sequences of the record.
