    Ok, heres the deal,

    My bass head (Peavey NitroBass) has a switch that changes from Passive to Active.

    Why is it that when the switch is set to passive, the volume is louder than when its set to active, although my passive bass is louder than my active bass anyway?

    Will it cause any damage to the speakers/head having the switch set to passive all the time?
  2. no all it is is a pad.

    its usually between -3db to -12db

    The active "switch" is just a pad to reduce the input signal. The purpose is to remove some of the "noise" that may be overamplified from an active circuit. I have a -10dB pad switch on my GK1001RB and I always leave it off. I just turn down the volume control on my active basses. As long as your input signal isn't clipping and your speakers don't sound like they're breaking up...shouldn't be any harm in running that in the passive mode all the time.
