| Inline Volume Control - What Resistance? |
| (1/3) > >> |
| 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 |

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". http://en.wikipedia.org/wiki/L_pad |

Thanks for the info. So I don't know what 'load' I would need. For example, would this one work? http://www.allelectronics.com/make-a-store/item/8MLP/8_OHM_L-PAD,_MONO_15W/-/1.html |

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. |
