Construction
Three-Chamber Structure
88FD
The power supply, digital processing, and audio circuit blocks
are separated by the three-chamber structure to eliminate
electrical and signal interference between the blocks, with the
power supply block and digital processing block enclosed in
separate shield cases. Each circuit is isolated to cut out
unwanted electrical signal to provide clear audio and video
reproduction.
Double-Layered Chassis
88FD 85FD
The 1.6 mm-thick chassis base is reinforced with a 3 mm-thick
plate. This Double-Layered Chassis structure provides a low
center-of-gravity and overall rigidity that prevents the transfer
of external vibration to the inner chassis, and offers a superior
reading of the disc.
Highly Rigid Center Frames
88FD
Inside the chassis, two steel center frames provide additional
rigidity, while an optimal layout is adopted to minimize
vibration and signal loss.
Steel Plate Top Panel and Aluminum Side Panels
88FD
To ensure rigidity, the 1 mm-thick steel plate top panel is fixed
at multiple points. Designed to eliminate the most minute
vibration inside the chassis, aluminum which has high damping
effect, is used for the side panels.
Steel Plate Bonnet
85FD
The 1 mm-thick steel plate bonnet provides extra rigidity to the
chassis.
Rigid & Quiet BD Drive
88FD 85FD
The high performance Rigid & Quiet BD Drive provides strong
resistance against vibration with its rigid structure.
Steel Shield Drive Case with Anti-Vibration Paint, Steel Drive
Base, Tray Shaft, Tray with Anti-Vibration Paint
The BD drive is housed in a shield case with anti-vibration paint*
and fixed to the steel plate drive base for reduced vibration. The
drive base and the chassis are fixed via the damper, so vibration
from the drive will not be transferred to the chassis. The tray
shafts on both sides provide a steady loading of the tray. A special
paint is applied to the disc tray for enhanced anti-vibration and
damping effect.
* Drive case anti-vibration paint only on BDP-88FD
Acoustic Damper Tray
The Acoustic Damper Tray features separate disc tray cover and
tray base which are connected by springs. The design provides
enhanced damping effect by preventing the vibration generated
inside the drive from being transferred to the chassis via the tray.
