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.

The Dual 1010 F in all the functions is similar like model 1010 A, but  in addition is equipped in function of variable speed control.
Pitch Control - each of the 3 standard records speeds (33-1/3, 45 and 78 rpm) may be varied up to 6% by means of pitch control. The selected speed may be checked using the stroboscopic disc supplied with the unit.
