View Full Version : ploc sound with new caps !

03-19-2005, 11:54 AM

I change the capacitor on my handmade xover for 43xx which were 25 years old ( new dayton on medium , hf , uhf )

works good but when I start on the amp , I can hear a "ploc" sound on the right speaker .
when I turn off and wait only 15 seconds : no ploc .

Thre must be something wrong but I do not know where to go ; I just test the continuity of caps and it's ok ( I am not technical aware ! )

Thank you for information.

- Was is Das ,,, "ploc" ?

- What do you mean by "ploc" ?

- Is it just a onetime pop ? or is it a more continous sound ?

- If the amp is left on - does it continue to "ploc" ?

- Are you sure that you rewired everything , correctly ?

- If one side is good / then swap the 2 networks around / to see if the problem is actually in the network .

Well it sounds like a "ploc" or "tac" very short and only once at medium level .

when the amp is on I just have it once on the start of the amp ...

I already check up but I will check again .....

Make sure you try swapping the networks from one box to the other - to see where the problem goes .

It sounds to me like more of an amplifier problem. What happens if you switch sides? Does it stay with the speaker or go with the amp?

In fact I test each speaker and there is a small "ploc" on left and a bigger one on the right but apart this ploc on the beginning it works perfect for me ...

I'll switch the map output the afternnon .
