Dual turntables (ad, June 1981)

Tunable, anti-resonance filter (Minimizes vibration and undesirable resonances in tonearm and cartridge.)

Tunable acoustic isolators (Adjust for maximum protection from acoustic feedback or external shock.)

Hydrodynamic suspension system (Absorbs spurious energy from sound waves and external vibrations.)

8-gram-ULM tonearm and cartridge system (Tracks warped records as if they were perfect makes all records sound better.)

Four-point gyroscopic gimbal (Maintains perfect dynamic tonearm balance and tracking throughout play.)

Any one of these Dual features had more advanced engineering in it: than most-complete turntables.
