Introduction
The McIntosh MT10 Precision Turntable with the McIn­tosh MCC10 Moving Coil Cartridge offers the latest in playback of vinyl recordings. A full complement of perfor­mance features allows for the enjoyment of all recordings reproduced with f lawless realism. The advanced electronic and mechanical design ensures many years of smooth trouble free operation.
Performance Features
• Advanced Technology Turntable
The MT10 combines the latest technology in Phono Car­tridges, Tone Arms, Mechanical Suspensions and Record Platter Rotation for superb performance and accurate operation.
Introduction and Performance Features
• Illuminated Speed Meter
The Illuminated Speed Meter on the MT10 indicates the true rotation speed of the turntable platter.
• Magnetic Air Damped Bearing
The MT10 Turntable Platter rotates on a special bearing using magnetic suspension together with a cushion of air to provide vibration free rotation.
• Multi-Layered Damped Chassis
The MT10 Turntable Chassis is composed from a Stainless Steel base plate, a thick Aluminium plate, an Acrylic plate and together with internal damping material all help to as sure the only sound heard is from the record groove itself.
-
• Moving Coil Cartridge
The McIntosh MCC10 Moving Coil Cartridge has a hand polished ebony wood-tone body and is slightly rounded, leading to a resonance free construction. High impedance, together with high output voltage, ensures noise free musi cal reproduction. The ruler-flat frequency response from 20Hz to 20kHz provides solid realistic bass, uncolored midrange and natural high frequencies.
• Tone Arm
The MT10 Tone Arm is made from Dural-Aluminium with special damping material. The Tone Arm is both light in weight and highly rigid. The noise free Veritcal Bearings are made from two high precision ceramic surfaces with damping fluid. The Horizontal Bearing is a gimballed sap phire design.
• Turntable Platter
The over twelve pound, two and one-half inch thick plat ter is made from a special silicone acrylic material. 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.
-
-
• Power Control
The Power Control Input connection provides convenient Turn-On/Off of the MT10 Front Panel 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 de signed 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 ensure the pristine beauty of the MT10 will be retained for many
­years.
-
• Precision Motor and Drive Electronics
The Swiss made DC Brushless Motor is controlled by a highly refined sevo control system. As the Turntable Plat ter rotates, an optical sensor “reads” the 1595 micro stripes on a disk affixed to the bottom of the platter. This provides precise feedback information to the sevo control system thus assuring very accuate speed rotation.
