LM3886, mute question...

CJ900RR · 9th March 2008, 02:08 PM

Short question. Is the cap in the mute-"network" really nessesary. Or is it just there to smoth out the mute function. Would a resistor to V- be enough to unmute the circuit?

What I can read from the datasheet it would be enough with the resistor, but I ask just to be shure.

The cap helps to delay the unmute, which helps avoid pops as the amp comes up to operating levels.
