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.

Moving Coil Dynamic Sterophones

Like other Signet products, Signet Stereophones are created in our electroacoustic laboratory. Assembly is painstaking, quantities are limited, testing is rigorous. And the standards reflect the highest technology available. There are but two Signet models; a moving coil dynamic and an electret condenser. Both benefit from the resources of one of the largest transducer manufacturers in the world. Yet each is also the product of a small group of skilled and dedicated specialists, the Signet Group.
