    Question Dumb Question

    When connnecting/disconnecting speakers should your receiver/amplifier be off? I've never been shocked but am curious if it is dangerous to do this with the reciever/amplifier on. I do turn the sound down so that I don't get loud bursts of noise going through the speakers.

    When connecting or disconnecting speakers you should do so with the power off.Damage to your amp could result otherwise.

    I don't believe the voltages are high enough for you to feel a shock, but as zapr says, your amp is what is vulnerable to damage, especially if your disconnected speaker leads accidentally touch each other and short out the amp.

    The amp should be off...

    I have seen a high power amp blow its entire right channel when disconnecting a pair of speakers (Quad 989's in this case) as the wires touched. Blue flash, terrible smell and $2,400 bill!!!

    I would shut the amp off, some amps can be damaged if you should accidentally short the speaker leads together.

    Thanks so much. Sometimes my cables came out of the speaker clips so I would just plug it back in with the amp on. Just the other day, the light came on and I asked myself wtf I was doing. From now on the amp goes off, because I surely don't want to fry my amp. Thanks again.
