When you wind the unit up, you're not only winding the
turntable, but you're "loading" the mechanical
amplification system.
It works by virtue of a system of levers. A wound up
spring provides the power for this amplification. When a
very small
vibration is sent into the system, it "releases"
the tension
provided by the spring and transfers the vibration to a
much larger diaphragm movement system than would be
possible with just the very slight energy coming from a
wiggling needle.
As far as tone manipulation, this is all handled by a
series
of frequency tuned baffles and absorption modules. You'd
actually be able to control bass, midrange and treble.
Steampunk hi-fi.

RE: Link. This is one of the reasons to get up in the

Not really, it's just a case of clicking the "link" button and then copying and pasting the URL. |
