Inline Volume Control - What Resistance?
myrmidon:
Hi All,
I would like to mount an inline volume pot somewhere beside the speaker (so that the player can adjust the volume 'on demand'). Can I simply wire this in series with the speaker to form a 'passive' downstream volume control? If yes, what resistance should the pot be?
Furthermore, (unfortunately I don't have any advanced electronics knowledge), what effect would such a pot have on the games? (BEcause the pot would be increasing the resistance on the speaker loop - is this bad for the audio amp?)
Thanks
WhereEaglesDare:
You need a pot that is designed for this application. A normal pot will increase the resistance, or impedance, but one designed to be a inline volume control will do what is called impedance matching and will not burn out your speaker output on your game. A normal one can blow your amplifier.

What you need is called an "L-Pad".

Aah, interesting (had never heard of that). Thanks for the info.
So I don't know what 'load' I would need. For example, would this one work?

if you are using pc speakers that already have a volume control knob, it may be easier to just replace/relocate that. I'm using logitech 2.1 pc speakers and will just be rewiring the potentiometer up to my mounted one. the original one is is a 10K linear.
