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.

Leak Delta Turntable

It is important that the turntable in your high-fidelity system should be specifically designed to complement in performance and appearance the other components in your system. To this end we worked with one of Switzerland's foremost turntable specialists to create the Leak Turntable.

It is a dynamically balanced turntable which weighs over half a stone, eliminating the distortions that occur in lighter turntables due to internal vibrations.

The chromium plated pick-up arm is so sensitive that it can be affected by the infinitesimally centrifugal force it creates as it moves towards the centre of the record. We compensate for this with a bias compensator utilising a minute counterbalance supported on nylon thread. The turntable also has a viscously damped pick-up cueing device. In spite of this precision the Leak turntable is, like all the finest machines, simple to operate and maintain. The speed of the turntable is infinitely variable between 30 rpm and 86 rpm.

The very silent 4-pole motor is spring mounted onto a rigid steel baseplate. The power is transmitted from the conical motor shaft to the turntable by a ruber covered idler wheel. The speed is changed by moving the idler wheel on the motor shaft.
