Speaker making strange sound when muted
Posted: Tue Nov 02, 2021 6:14 pm
Hi guys. I'm hoping someone could help me wire up the volume wheel. It's 5 stereo, but only hooking up mono.
So far the headphone jack works & the speakers work whenever I unplug the headphone jack.
Headphone jack: PJ-325
Volume wheel: B103
Amplifier: PAM8403 green
The wiring is:
Low pass filter - Headphone Jack - Amplifier - Speaker.
I currently have the volume wheel connected between L in & Speaker - on the amplifier. Everything is connected to the left output speaker in mono.
The volume wheel is working if it's not completely muted, but makes a horrible noise when muted.
The same noise occurs when I plug something into the headphone jack.
I tested using a different potentiometer & got the same issue, so much be wiring?
Any advice would be appreciated, thanks!
