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.

Dynavector DV/20A and DV/20B Type2


 These cartridges are the successors of the famous Dynavector Ultimo 20A and 20B types which have been enjoying such very good world-wide reviews for their excellent musicality, technical performance and unusually high output voltage for moving coil construction.
Based an this very great success, we have re-designed them to even higher standards. Both the 20A and 20B Type 2 can now deliver an amazingly high output voltage of 3,6 mV, together with an astonishingly flat frequency response to 20 kHz.
The tracking ability is superb to match the most difficult direct cut discs. All its predecessors features are retained, but great technological advancement has given the new Type 2s more easiness and musicality. Thanks to very high output voltage and the light weight of the new models, many more music lovers will be able to enjoy the realistic sound of the moving coil construction without the nuisance or added expense of additional transformers or pre pre-amplifiers.
