Empire 598 III Turntable
Created by concentrating our total effort on a single superb model.
The Motor
A self-cooling, hysteresis synchro nous type with an inside out rotor, drives the platter with enough torque to reach full speed in one third of a revolution. It contributes to the almost immeasurable 0.04% average wow and flutter value in our specifications.
The Drive Belt
Every turntable is packaged only when zero error is achieved in its speed accuracy. To prevent any variations of speed we grind each belt to ±0.0001 inch.
The Platter
Every two piece, 7 lb., 3 inch thick, die cast aluminum platter is dynamically balanced. Once in motion, it acts as a massive flywheel to assure specified wow and flutter value even with the volt age varied from 105 to 127 volts AC.
The Main Bearing
The stainless steel shaft extending from the platter is aged, by alternate exposures to extreme changes in temperature, preventing it from ever warping.
The tip is then precision ground and polished before lapping it into two oilite, self lubricating bearings, reducing friction and reducing rumble to one of the lowest figures ever measured in a professional turntable; -63 dB CBS ARLL!
The Suspension
Piston damped, 16 gauge steel coil springs cradle the arm and platter. You can dance without your stylus joining in.
The Tonearm
The aluminum tubular design boasts one of the lowest fundamental frequencies of any arm, an inaudible 6 Hz. Acoustic feedback is unheard of, even with gain and bass turned all the way up. The vertical and horizontal bearing friction is 1 milligram. This allows the arm to move effortlessly imposing only the calibrated anti-skating and tracking force you select.
The Cartridge
Empire's best, the 4000D/III, wide response cartridge is a standard feature. The capabilities of this cartridge allow you to play any 4 channel or stereo record at 1 gram or less. And the frequency response is an extraordinary 5-50,000 Hz, with more than 35 dB channel separation.
The Controls
The coordinated anti-skating adjustment provides the necessary force for the horizontal plane. It is micrometer calibrated to eliminate channel imbalance or unnecessary record wear.
Stylus force is dialed with a calibrated clock mainspring more accurate than any commercially available stylus pressure gauge.
A true-vertical cueing control floats the tonearm up or down from a record surface bathed in light.
At Empire we make only one model turntable, the 598111, but with proper maintenance and care, the chances are very good it will be the only one you'll ever need.
