T 405 / K405 UHF Muting Sensitivity

[DrWT]

I post this new topic into this section.
Not being mislead by the bunch of mike topics, I believe, I am perfectly right here. 

Whenever I switch on my headphone T 405 / K405 UHF, there is only signal noise to be heard.
I have to unplug and reconnect the Cinch connector(s) in order to generate a terrible cracking sound.
Then everything is fine for some minute(s) or so.
Sometimes the function stops when I listen to soft music.

Apparently the muting level in the transmitter circuit is set too low.

There are a lot of pots on the transmitter board.
I assume that one of them could be responsible for adjusting the muting level.

But which one??

Any advice is appreciated.

Dear Walter,

please dont touch any of the potentioneters inside - it will not work better after turning some of them.
The only way to eleminate your problem is to make the incoming signal source louder.

kind regards

Hello micdoctor,

Thank You for the warning and the advice.

I do not dare to touch any of the pots without knowing their function.

My idea was to make the incoming signal louder by adjusting the appropiate pot!

Best regards

It appears that nobody has any knowledge about the appropiate pot for solving my reported sensitivity issue. 
A schematic would be helpful to understand the circuit and to determine the variable resistor I am in chase of.
Even if there should not be a pot, where I assume it to be, exchanging a fixed resistor would change the sensitivity the same way.

If someone does not dare to publish the facts for me, I do not mind about a PM. 

Best regards

Hi Walter,
once again, raising the gain of the incoming signal eleminates your problem - you dont have to exchange anything !
