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 SP25 Mk II

 Designed to meet the demand for a high-quality single record playing unit at moderate cost, this unit incorporates a number of special features including a cue and pause control, calibrated fine  stylus force adjustment, pickup arm bias compensation and a large turntable. On completion of playing a record the pickup arm automatically rises, returns to its rest and the motor switches off.
 The Garrard SP25 MkII is a 4-speed single record playing unit incorporating an improved tubular aluminium pickup arm with a resiliently mounted counterbalance weight and a calibrated dial to set stylus force easily. It is elegantly styled, and has many features associated with more costly equipment, such as a cueing device to lower and raise the pickup gently, a patented pickup arm bias compensator and a lightweight plug-in pickup shell which will accommodate a wide range of cartridges. In addition it has a large, loaded turntable driven by a magnetically screened resiliently mounted Garrard Laboratory Series electro motor, through a retractible rubber wheel. The pickup returns to its rest automatically after playing a record and unit switches off.
