Hi all
Is there any way to decrease minimum audio level without soldering?
Thanks in advance
Best regards

There is a resistor on the volume control board. Short it out and the volume will go to zero.

Could you please point me to this resistor?
Which one exactly is?

It's the only resistor on the board with the Volume Control and MIC jack. It's a 10 ohm axial-lead resistor. Just short it out.

Why not just remove the pin jump from the rear if you want no volume?

Hi tsunami
I'm not going to permanently disable audio. I would like to have possibility to decrease audio volume to the level closer to "0" using potentiometer.
