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.

DUAL 1010 A

Auto/Standard Turntable for single play and changer operation.
The ingenious design of the top/mounting spring screws makes it possible for you to mount and secure the Dual 1010 to its base - or to the cutout mounting board of a console -  entirely from the top. No need to fumble underneath, nor to take anything apart.
The Dual 10101 tonearm is designed for tracking at the low stylus forces required by high compliance cartridges. Once adjusted for your cartridge, the force will remain highly linear for a complete stack of records. Stsylus force is adjusted by turning the knob located at the pivot; clockwise to increase force, counterclockwise to reduce force. The range of adjustment is from 2 to 7 grams, with clock stops at 1/2 gram increments.
The tonearm has been set to descend accurately into the lead-in groove. But if the dimensions of your cartridge and/or the location of its stylus cause the lattere to touch the record either too far in or too far out, it can be adjusted quite easily.

All the operations of the Dual 1010 are activated by smoothly acting slide switches. Unlike push buttons, they do not jar the spring-mounted chassis or induce even momentary vibration. Thus the three spring-mounted footings of the Dual can enjoy a softer, more shock-absorbent characteristic, rather than a compromised stiffness.
