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.

Ortofon MC 10

There are as many expert opinions on HiFi as there are experts. With all the variables, an incredible range of systems can be produced and all have their different advantages but almost all experts agree that moving coil is superior to magnetic construction for cartridges.
Moving coil's  detailed reproduction of spaciousness, three dimensional imagery and startling transient response surpasses that of even the best magnetic cartridge.
There is really only one choice if you wish to take full advantage of the capabilities of your HiFi system. Until now the high cost of the hand built moving coil cartridge has kept peak performance beyond the reach of all but the most wealthy.

Now Ortofon who have continuously developed moving coil technology since 1948, are able to produce a moving coil cartridge at a price which compaares to the cost of medium quality magnetic cartridges.
Ortofon's long experience of cartridge design and manufacture make the finest reproduction available to all discriminating listeners with the MC 10 moving coil cartridge.

The MC 10's caantilever has been designed on new principles, making it easier and faster to produce. It is as light and as rapid as possible, utilizing a new aluminium alloy. The new cantilever design, together with a tiny, specially polished diamond, gives a very low stylus tip mass,excellent tracking ability, easy handling of transients and minimal record wear.
Owing to their small output voltage and low inner resistance, moving coil cartridges cannot be connected directly to a conventional phono input and it is therefore necessary to boost the signal.

MC 10 Cartridges are available separately or in a cost saving pack complete with the specially developet STM 72 step-on transformar for perfect matching to your amplifier.
