DIRECT-DRIVE with optically-actuated auto lift and shutoff
The direct drive DC servo motor is featured in the Marantz 6300 for three
compelling reasons.
One: The shaft of the motor is directly connected to the center of the turntable for more accurate rotation.
Two: The direct-drive motor eliminates the need for belts, pulleys and other mechanical parts that increase friction, impair accuracy.
Three: The DC motor is electronically, controlled for even greater precision. And precision is what the 6300 s all about. That's why Marantz design engineers chose the manual system in the first place.
Then they incorporated optically-actuated auto lift and shutoff to afford the Marantz owner automatic convenience without sacrificing quality.
Here's how it works:
When the tonearm is in position over the lead-in record groove, the manual/ auto push switch is on "auto" and the Cue Down switch is depressed, the platter will rotate and tonearm will descend. At the end of the record, a beam of light activates an electronic circuit that automatically lifts the tone arm and shuts off the unit. This optical circuit replaces mechanical linkage. Result: no friction, no mechanical wear. And viscous damped cueing provides smooth tone arm lowering and raising.
Stroboscopic control--again sophisticated optics come into
play. Surrounding the edge of the platter are small aluminum dots that are
illuminated by a neon strobe light during play. The light on the moving dots
creates easy-to see patterns that visually indicate platter speed. Here's how:
Once you have depressed either the 33-1/3 or 45 RPM selector push switch and
activated the platter, the moving-dot patterns will begin. Then you simply
turn the pitch control until the moving dots appear to stand still. Now you've
accurately set the speed for the original recorded pitch. If you wish to adjust
the pitch to your personal taste, turn the control for a variance of ± 3%.
The Marantz S-shaped static balanced tone arm has an easy-to-read tracking force control knob and vertical and lateral counterbalancing, plus Marantz anti-skate for still greater accuracy. There's even a plug-in cartridge shell for convenient cartridge exchange and a storage-mount for holding an extra cartridge.
The 6300. From its hinged dust cover, to its anti-static turntable mat, right down to its adjustable shock absorber feet, it's all Marantz. Common sense design with the future in mind...like the low capacitance phono cables that assure 4-channel capability whenever you need it.
