View Full Version : Is the point to make the platter as dead as a wet noodle, or .....

Should it still retain a slight ring? I say this because between the roofing tape applied to one part of the platter, and silicon tub caulking on the underside where the balance weights are applied, and the Target mat on the top, the platter is dead; like the parrot in the Monty Python skit. The turntable is now eerily quiet, and records take on a different personality. Does ringing ruin the sound, or add to its charm? Did I overdo the damping thing, or should I be applauded for producing an inert platter? I have never heard such a quiet idler-drive turntable.
Thoughts please.

Dead is best. :thmbsp:
The idea is to drain off any resonances produced by the stylus and transmitted to the platter via the record. Otherwise it's like having an overly live room. Think of trying to get the turntable/record combination to sound like the master tape. No echo, ringing or other sonic artifacts should be introduced to the reproduction chain. :banana:

Do you have some wierd fettish when it comes to farts and crapping? What do you find so cute about it, that you have to share it with us at the end of each post? :puke2:
Just real curious, because it is so vulgar.

is that true because when off the table one platter i have has a full ring when tapped
like a bell if so what is deeded to deaden it?


Any damping tape, putty or viscous material will do, but consider this:

Off the table ringing is damped when it is "on the table". You should have concern for any ringing that still exists when the platter is resting in place. A dead platter will likely still be dead once installed, but the resonance of the table, rack, amp, or room furniture add to unwanted vibrations and should be toned down with damping to lower their resonant frequencies. All items resonate, you just want them to do so below the frequencies in your music.

Rediculous to do, but the resonant frequency can also be raised above the frequencies where it can do harm to the tracking.
For example: the arm of my Dual 1229Q has carbon-fiber (very space-age for 1974) parts. I believe that carbon fiber has resonance properties very different from zinc and aluminum alloys. It would raise the resonant frequency of the arm, right? It must do something, because it cost a bundle to make that stuff in 1974.
