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.

McIntosh MT-5 turntable


McIntosh MT-5 precision turntable
MT-5 is a complete turntable package that is more than the sum of its parts. Engineered to exacting McIntosh standards, each piece contributes to its superb performance.
Advanced Technology Turntable
The MT-5 combines the latest technology in Phono Cartridges, Tone Arms, Mechanical Suspensions andRecord Platter Rotation for superb performance andaccurate operation.
Tone Arm
The MT-5 Tone Arm is made from Dural-Aluminumwith special damping material. The Tone Arm isboth light in weight and highly rigid. The noise freeVertical Bearings are made from two high precisionceramic surfaces. The Tone Arms lateral movement isperformed by a high precision Horizontal Bearing. Italso incorporates adjustable magnetic Anti-Skating.

Turntable Platters
The full size Outer Platter is made from a special silicone acrylic material weights five pounds, one and one-half inch thick. This helps to resist external vibrations from reaching the record during playback and its large mass provides the perfect flywheel action for stable playback speed. The inner platter is precision machined Anodized Aluminum weights one and one-half pounds and is six and one quarter inches in diameter.
Precision Motor and Drive Electronics
The Swiss made DC Motor has stainless steel brushes and is controlled by a highly refined servo control system assuring very accurate speed rotation.
Three Playback Speeds with fine Adjustments
The three playback speeds include 33 rpm, 45 rpm and 78 rpm. There is a separate trim adjustment allowing for accurate music reproduction for each of the three speeds.

Magnetic Air Dampened Bearing
The MT-5 Turntable Platter rotates on a ceramic bearing using magnetic suspension together with a cushion of air to provide vibration free rotation.
Multi-Layered Dampened Chassis
The MT-5 Turntable Chassis has a Stainless Steel base, with a thick Aluminum base plate and Acrylic top plate. The internal dampening material also helps to assure the only sound heard is from the record groove itself.
Power Control
The Power Control Input connection provides convenient Turn-On/Off of the MT-5 Illumination when connected to a McIntosh System with Power Control.
Fiber Optic Solid State Illumination
The even Illumination of the Front Panel and the Turntable Platter is accomplished by the combination of custom designed Fiber Optic Light Diffusers and extra long life Light Emitting Diodes (LEDs).
Glass Front Panel and Super Mirror Chassis  Finish
The famous McIntosh Illuminated Glass Front Panel and the Stainless Steel Chassis with Super Mirror Finish ensures the pristine beauty of the MT-5 will be retained for many years.

Features: 
MT-5 is factory adjusted for perfect playback. Tracking force, anti-skate force, cartridge overhang and arm height are all preset for maximum performance.
While the construction of the MT5 is meticulous, the setup is simple. In a few easy steps, you’ll be ready to enjoy your favorite vinyl recordings.
While maintaining complementary McIntosh styling, the MT-5 takes full advantage of the chassis materials used to suppress noise, resonance and coloration so the only sound produced is that which is on your records.
Includes a clear, form-fitting dust cover to protect moving parts and your records.
