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 GT-35 turntable

The GT35 is a perfect example of meticulous engineering. Everything about it - its impressive rumble, wow and flutter specifications, its low tonearm mass and low bearing friction - confirm the visual and tactile impressions you get of high performance.

The tonearm

Garrard engineering has given special attention to this critical aspect of record play. The tonearm of the GT35 weighs just 12 grams, lower than any automatic turntable in its price range. The tonearm features an ultra-light magnesium headshell and jewel bearings ensure that the finest and lightest tracking cartridges will perform up to their maximum capability.

The motor

A DC servo-controlled unit incorporating electronic sub circuits in a self-correcting network. Rumble, wow and flutter specifications rival the finest turntables, including the expensive direct drive units. The GT35 motor rotates records at rock-steady speed with total freedom from AC vibration.

The platter

Dynamically balanced and die-cast from a special aluminum alloy, assuring uniform density. It is rotated by a precision-ground flexible belt, further reducing vibration. The GT35 specifications are well within the professional transcription category.

 

 

Variable speed

Electronic control with independent adjustments for 33-⅓ and 45 rpm. Correct speed is monitored by a stroboscope cast into the periphery of the platter. It is illuminated by an LED ( rather than the usual neon) resulting in a distinct image easily read, even in a brightly lit room.

Base and dust cover

Both the glass filled polyester  upper section and lower wooden section of the base form a barrier against vibration and resonance. Special shock absorbent feet minimize acoustic feedback. The dust cover pivots freely and can be raised and lowered even while a record is being played.

The Delglide Automatic System in the GT35 offers unerring accuracy and silent and sure operation. The combination of measured performance and features achieves the goal of its designers totally gratifying music reproduction.
