to perimeter, this tends to vary the resonant frequency within the foot—diffusing
one potential path for vibration. To further deaden vibration, the feet of the DVP-
NS999ES use non-rebound rubber on the bottom.
Locating the insulator feet screw holes off center means a constantly
varying radius from the hole to the edge. This diffuses shelf-borne
resonance.
Advanced FX Mechanism (DVP-NS999ES)
Not only the chassis but also the disc drive mechanism itself is designed
to minimize resonance. Sony's Advanced FX Mechanism includes four important
advancements:
The Fixed Base Unit improves tracking stability and reduces transport
vibration at the source.
The Hermetic Shutter controls air-borne vibration.
Sony's BMC mechanical deck helps prevent resonance from affecting disc
playback.
The Precision Drive™ 2 system helps provide accurate, uninterrupted
playback even with warped, scratched or dirty discs.
Fixed Base Unit Mechanism (DVP-NS999ES)
On a conventional CD or DVD drive, the spindle, drive motor and optical
pickup are mounted on a pivoting base unit. The pivot is necessary because the
base unit needs to drop out of the way when the disc drawer is opening and
closing. And it needs to swing back up into playing position once a disc has
been loaded. Unfortunately, this pivoting mechanism is an open invitation to
vibration and resonance.
Sony engineers demanded more. For the DVP-S9000ES, they developed
the fixed base unit mechanism. Sony's DVP-NS999ES incorporates the second
