Dbx 3bx pops


Hi People, i rarely ask in the forum, but this problem is driving me kinda crazy. I have a 3bx ds dynamic range expander that i use with my turntable and, only with certain albums and certain songs, it makes a poping sound. The "pop" sound always happens in the same part of a song, so it's not random, and it depends on how much expansion or impact restoration i have dialed. Could it be that the dbx is making my amp clip? (i have a cambridge axr 85 amp). The popping sound is so loud that it scares me everytime...but it only happens if im using the dbx. 

In this video you can clearly hear it after the part that says "New York times"

Hello mofimadness. The pop only occurs in a specific part of a song, and always on the same part. I can put the stylus in that section of the song, and it will pop every time in that specific part. I tried with other albums, and it's the same, so it's not the LP.  You are right, it sounds like a discharge to me as well, but I think if that was the case, the pop would be random. 

Exactly, when i turn up the expansion level, the "popping" starts. In some cases, like in this album, i cant turn the knob even a millimiter without popping, so i assume its related with the frequencies of the song. I will check again if all the caps are ok just in case, but this problem im having its in fact really weird.

Hi islandmandan, how are you doing? I know this is kinda taboo to say in the audiophile world, but i really like the effect that dbx provides. It makes the music more "spacious". Although, it is true that without the dbx in the chain, my system doesnt have any problems hahaha.
