The Dual 508
Extraordinary performance at a surprisingly affordable price.
Single-play,
Vario-belt drive turmtables.
Dual
Exclusive Features:
ULM tonearm
and cardridge system; less than 8 grams total effective mass.
New XM300
allow tonearm increases rigidity, reduces resonance.
Tunable
acoustic isolators minimize acoustic feedback and external shock.
Vario-belt
drive with hightorque synchronous motor.
HDC (High
Damping Compound) housing provides high internal damping and suppresses
external interference.
Unique
dust-cover hinges allow placement close to rear wall.
Unique
Vario-Belt Drive
The 508 also
feature Dual's unique, patented Vario-belt drive system with high-torque
synchronous motor, Vario-pulley and precision-ground belt.
Speeds can
be changed even while the platter is rotating, and the belt is never twisted or
distorted. Speeds are adjusted by expansion.
The moment
the ULM tonearm touches down on your favorite record, you will appreciate what
Dual engineers have accomplished. You will hear a purity of tone that has never
before emerged from the grooves. Even if the record is warped.
ULM : Ultra
Low Mass
ULM is
Dual's exclusive Ultra Low Mass tonearm and cartridge system with total
effective mass less than 8 grams. That's less than half the mass of
conventional tonearm and cartridge combinations. This major breakthrough by Dual has been
acclaimed throughout tha audio industry, especially by the independent test
labs. These labs have begun to use warped records as "real-life" test
instruments.
