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 2001 turntable

Transcription Turntable

The new leak 2001 transcription turntable incorporates a unique spherodynamic method of isolating against external shock vibration and acoustic feedback. Small jolts which can damage an expensive record are eliminated.

The turntable itself is belt driven and its speed does not vary by more than 0,1% even when using a record cleaning device.

The synchronous 10 pole motor with a ferrite rotor ensures accuracy of speed even with changes in supply voltage and loading.

The precision engineered pick-up arm accommodates all cartridges with standard 127 mm mounting centres and has adjustable bias setting and adjustment for minimum tracking error with any cartridge.
