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.

Garrard 401

 The Garrard 401 which operates at three standard speed is produced to the highest  technical specification to meet the most exacting requirements of radio, television and recording studios as well as for high-fidelity enthusiasts.
Styled by one of Britain's leading designers it presents an elegant appearance in metallescent charcoal with chrome relief. The balanced, machined turntable is an aluminium, gravity casting weighing approximately 6 lb.
Accurately spaced, gear-cut stroboscopic markings on the periphery of the turntable are illuminated by a high-intensity neon lamp situated in the rigid aluminium base plate.
This is a unique feature of the 401 and enables the user visually to check that the turntable is running at exactly the correct speed.
 Fine speed adjustment is achieved by means of an eddy current brake; a control on the unit base allowing the speed to be veried by plus or minus 3 per cent.
The high - and low-range (110 -125 V and 220-250 V) shaded-pole induction motor, encased in a heavy iron casting to provide full magnetic screening, is isolated from the base plate by six tensioned springs. This provides an effective vibration barrier between the motor and the rest of the unit. The spindle is machined from a high grade of steel which is then hardened, tempered, ground and superfinished.
A double-pole switch is used for the power supply to the motor and is fully supressed. Each unit undergoes the most rigorous inspection and test, and the final performance figures are recorded on an individual test report which accompanies the unit.
 Every Gerrard Unit is 100% inspected on the very latest electronic test equipment to make sure that it conforms to the high standard of quality and reliability for which Garrard are world-wide renowed.
All Garrard units are wired for stereo reproduction (also suitable for mono) and all automatic turntables have facilities for manual (single record) operation.
Each model has been specially designed to meet specific and exacting requirements giving a complete range from the highest quality transcription tuntable to the popular priced automatic and single record-playing units.
 Leading designers keep Garrard to the forefront in contemporary styling.
Special durable finishes are used, making every Garrard unit suitable for tropical conditions.
Each unit is supplied with template (giving all dimensions), transit or fixing screws, installation and operating instructions.
Units not supplied with pickup cartridge should be fitted with the cartridge of your choice. For advice, consult your dealer.
All Garrard models are designed to play records conforming to I.E.C. Publication 98, BS1928;1965, and equivalent national standards.
