When we told you Acoustic Signature didn't overlook anything in the design
of their turntables, we meant it. Recently the engineers redesigned the
motor electronic to better meet your needs. The result is the AlphaDIG Motor
electronic. The perfect engine for your Acoustic-Signature turntable. All AC
synchronous motors are normally speed-linked directly to the frequency of
the main voltage from your wall.
A simple transformer is all that most manufactures use to convert wall
voltage to the motors input. This is problematic for several reasons. The
voltage from your wall contains quite a bit of "noise", spikes and
distortions, that can seriously affects the performance of the motor,. The
result is an unsatisfying listening experience. And your fun listening music
depends extremely from the quality of main power. The AlphaDIG completely
decouples your motor from your wall voltage, making the Acoustic-Signature
turntable invulnerable to AC power fluctuations. This is achieved through a
series of refinements. In this brand new design we use fully digital output
stages and a quartz locked technology.
It is impervious to the negative effects of mains voltage fluctuations and
household appliances that produce ‘noisy’ mains that can have a very great
detrimental effect on AC motors and therefore the turntable performance and
ultimately the sound. And a quartz precision DSP then produces a perfect
sine wave at 24VAC to run the motor, resulting in a perfectly steady and
constant platter rotation. The AlphaDIG control is the perfect design
solution. The AlphaDIG is impervious to the negative effects household
appliances can have on a turntable.
The AlphaDIG can power up to three separate motors. Similar power supplies
cost hundreds, even thousands of dollars. Acoustic Signature provides the
upgraded AlphaDIG with every Ascona or Thunder
turntable at no extra cost. For the other models the Alpha-S is included.
Which also generates the sine wave internally but in a more conventional
analog design. The Alpha -S is able to drive one motor. From the wall to
your ears no stone was left unturned. Using the Alpha improves the sound
quality of the turntable in a very effective way.
