Adjustable volume on soundboard
I am going to use this Adafruit Audio FX Sound Board Product ID: 2210 in a museum exhibit, and I was wondering if it is possible to convert it to mono or to add a variable volume control. Thanks in advance.

Re: Adjustable volume on soundboard
You would need an external amplifier to have a variable volume control (I assume you mean a knob or slider). To get mono you would need an external circuit to mix L+R or just use mono sound files.

Re: Adjustable volume on soundboard
Would it be possible to place a potentiometer between the sound board and external amp to achieve this? What value pot would work? Once again, thanks for your help.

Re: Adjustable volume on soundboard
An amplifier should have some sort of gain control. That's a better approach. Just a note, if you are using an external amp, use the L/R pins on the edge of the board (which are line out level) rather than the amplifier output.
