I have been playing with this with a few of my records. I believe I am using this properly (at least according to the Jay Rose blog reprinting some of the instructions from the manual). I do notice the high-frequency filter doing its job properly, but I think the unit is introducing more crackle, not removing it.
KLH Burwen TNE 7000A Transient Noise Eliminator
Hello. Does anyone have any experience with this unit? I recently bought one and am not sure if it's working properly (I really don't hear it making any impact on my records). Perhaps I'm not setting it up properly. Also how do you all feel about using this along with the SAE 5000A unit (I understand this is better for the louder single pops).
Thanks
Thanks

I just did a test and engaged the unit with a CD. It was only in the very extreme sensitivity and threshold settings where I was hearing the same noise (crackle) that I noticed on records. This crackle that I'm hearing is music being removed. When I back off on those settings, that crackle goes away. So I guess the unit is working properly. I guess I still have to learn to properly fine-tune the unit to balance the noise it's removing without impacting the music. |
Ok. I played with it more last night and realized that whenever the transient noise eliminator LED lit, I heard a tick (although it could have been a hole in the music from the removal of a noise impulse). If this is the case, should I hear this hole in the music? I did have my ear next to the speaker listening for this so I guess I should probably try the same passage but sit in my normal listening spot. I do remember that my SAE unit has the same audible artifact but since the pops it removes are much louder, the artifact is more acceptable than the original pops. |

The TNE uses a "bucket-brigade" type delay to replace the click so that there’s no audible effect from removing the click. If you hear a click every time the LED is lit, either the clicks exceed the ability of the TNE to remove them, or the TNE needs service. In proper use, it’s very difficult to detect that the TNE is in the circuit. |
I have one of these for a few years now, they work. Audio Proz in Boston will upgrade yours for about $250. VInce, the owner, worked with the designer and is an expert on these. I have spoken with him, if you have any questions call him, he loves to talk audio electronics .https://www.audioproz.com/AP.php?About_Us If I had $2000 I would buy a Sugar Cube, digital pop and click remover. |
