Introducing Accutrac. The only turntable in the world that lets you tell an LP which selections you want to hear, the order you want to hear them in, even how many times you want to hear each one.
Sounds like something out of the 21st century, doesn't it? Well, as a result of Accutrac's electro-optics, computer programming and direct drive capabilities, you can have it today.
Just imagine you want to hear cuts 5, 3 and 7 in that order. Maybe you even want to hear cut 3 twice, because it's an old favorite. Simply press buttons 5, 3, 3 again, then 7. Accutrac's unique infrared beam, located in the tonearm head, scans the record surface. Over the recorded portion the beam scatters but over the smooth surface between selections the infrared light is reflected back to the tonearm, directing it to follow your instructions.
What's more, it can do this by cordless remote control, even from across the room.
The arm your fingers never have to touch.
Since Accutrac's tonearm is electronically directed to the record, you never risk dropping the tonearm accidently and scratching a record, or damaging a stylus.
And, since it cues electronically, too, you can interrupt your listening and then pick it up again in the same groove, within a fraction of a revolution. Even the best damped cue lever can't provide such accuracy. Or safety.
What you hear is as incredible as what you see.
Because the Accutrac servo-motor which drives the tonearm is decoupled the instant the stylus goes into play, both horizontal and vertical friction are virtually eliminated. That means you get the most accurate tracking possible and the most faithful reproduction.
You also get wow and flutter at a completely inaudible 0.03% WRMS. Rumble at -70 dB (DIN B). A tracking force of a mere 3/4 gram. And tonearm resonance at the ideal 8-10 Hz.
The Accutrac 4000 system. When you see and hear what it can do, you'll never be satisfied owning anything else.
Its father was a turntable.
Its mother was a computer.
