lock and mute LEDs on Buffalo II

Zapped · 11th May 2011, 06:47 AM

Is there anything about the specific LEDs supplied with the Buffalo II that is critical for optimal circuit operation, or can I substitute others? I want to mount a small amber LED for mute, and a small green LED for lock on the front panel of my enclosure, so I can tell them apart from across the room.

BTW, what exactly do these two LEDs indicate? "Mute" seems like an understandable term, but what exactly is being muted? Same question for "lock".

Sorry if this seems dim-witted. Mea culpa!

Different color LEDs have a different forward voltage. Not significantly different, though (blue and white having the highest Vf). You may want to adjust the series resistance with your new LED. Otherwise there's no problem at all.
Mind you I'm not familiar with the Buffalo II. Yes, "Mute" should be just that - the output is attenuated ~100dB. "Silenced". "Lock" I assume disables controls so that they cannot be inadvertently changed. Same thing you find on consumer audio portables.

Lock indicates a signal lock

The only thing you need to avoid with LEDs is Hightower out LEDs that would draw too much current.

Thanks to Brian, and to Sofaspud, for the information and advice.
