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.

Cambridge 540P

Cambridge 540P - MM phono pre-amplifier
The entry-level 540P is a high quality Moving Magnet design featuring single-ended "Class A" gain stages and a discrete transistor input stage instead of the more common integrated circuits. The 540P employs a highly accurate active RIAA equalisation system. The rear panel benefits from gold plated input connectors to minimise signal path interference and reduce surface degradation. An external 12 volt power supply comes as standard.
This unit feature the now customary Azur steel chassis and a robust anodised aluminium front plate.
