I Have Airborne Feedback And Never Realized It...Till Now


  While my ZYX Airy is out for a rebuild, I hooked up my CAL cd player/transport and started playing CD`s that I had recorded from vinyl using a Tascam 900.
When I do the recording, nothing is on but the TT setup and the recorder. Room is dead silent. No speakers

I`ve  been listening to a disc or two over the last few nights.

Last night, I was listening to a CD I made of Lindsey Stirling`s 'Shatter Me' LP
I was hearing so many odd/different sounds that I never picked up on before using the TT.

For example, I heard growling sounds (seriously) back ground noises and other THINGS that all were hidden when I was playing the TT.
This LP is Bass Heavy! Lots of energy in the air. With 3 15" subs I know that.

My TT is pretty much isolated IMO
I use a Rega wall mount bracket that is bolted to my equipment rack not the wall.
I have the TT sitting on a SRM isolation platform that sits on the Rega bracket
Concrete slab floor.

No doubt the cartridge is picking up on all energy that and resubmitting it.

This won`t be an easy fix I`m afraid..  :(

Good, normally you need much more and not only at first reflection points, probably you need some serious bass traps. 
If so then you need a room treatment, order acoustic analysis of your room and buy absorbers, diffusers and bass traps for your room.

Concrete floor is the worst material for listening room, if your walls are similar then it’s terrible.
Audio-Technica designed pneumatic insulators (AT-616) long time ago and this is still the best solution for turntables under 60kg weight.
