Hi I’ve read in a few places that plugging the amplified speaker out from a receiver into an active speakers in is bad but never why this is. Can anyone explain why? Can signals not be amplified multiple times, or is it because there is a higher likelihood of exceeding the wattage that the speakers were designed to handle? If that’s the case would keeping the receivers out volume low reduce the risk of damaging the speakers? More specifically I’m looking into getting powered speakers with the intention of getting a decent turntable at a later time. My current receiver has low power output: Emerson AS2630 with 15 watt output per channel Speakers: Klipsch R-51PM speakers rated at 60W per channel.
If you don’t have RCA pre outs, headphone to stereo RCA’s would work but still not be ideal depending on which active speakers you have.
The input to an active loudspeaker (one with an internal amplifier) can easily be be overloaded if driven from the speaker output of another amplifier.
The active loudspeaker expects a “line level” signal of 1 or 2 volts maximum. Even a low powered receiver puts out much more than that .
