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 1214

The Dual 1214 auto-manual turntable offers the same precision engineering as our more expensive models plus ease of operation and many outstanding features, usually not found in a unit of this price range. The dynamically balanced tubular tonearm combines low mass with high rigidity. Tracking  force is applied by rotating a numerically calibrated dial to the desired settings. Anti-skating is easily adjustable. The adjustable silicon damped cueing system, functioning both in manual and automatic mode, allows the tonearm to be lowered to any groove of the record. The master switch is operated by means of a feather-light, horizontal sliding lever, for shock-free operation.
Variable pitch control allows all three speeds; 33 ⅓, 45 and 78 r.p.m., to be varied over a 6%range, which is equivalent to about half tone.

The 1214 comes complete with a Dual Ceramic Cartridge. Choice-wood base and hinged smoked-glass cover are available as optional extras.
Dual's silicon damped feather-touch cueing system is a truly professional feature. A flick of your finger releasses the tonearm to float down at the controlled rate of 3/16" per second. Piston action prevents side-shift of the tonearm. The cueing device will function both in manual and automatic mode. Cueing height is easily adjustable for single and multiple-play.


Tracking force is set with a continuously variable dial and is applied internally by a long main-spring colled around the pivot. This ensures maintaining of proper tracking force at all times, whether with one record or a stack of six.
Variable pitch control is another professional feature for perfect "tuning" to pitch tolerances of individual records. Also valuable for synchronizing tape recording and movie sound.
The low mass, rigid, tubular tonearm has near-frictionless movement in the vertical and horizontal planes due to hardened steel pivots, each supported by minniaturized ball bearings.
The counterbalance weight of the tonearm is easily adjusted for true dynamic operating balance. The Dual 1214 is supplied with a factory installed Dual Ceramic Cartridge.
