Plate amp speaker level input effect

[kenmcculloch]

My friend wants to add a sub to his main speakers. He doesn't have a sub out on his amp. Anyone have knowledge as to sound from the amp by using the speaker level inputs rather than the low level RCA inputs? Thanks.

Not sure exactly what you're asking.. but basically, it just works. There should be no sound quality difference from the sub's point of view, it just samples the amp out voltage, and uses that, rather than a line level voltage.

You may have to adjust the level on the amp, it likely will be different from what was right with the line in. And, if you're using the line in for HT, you probably need to adjust THAT level out so it won't be too strong/weak with the speaker level setting. Then everything should be in balance.

Now if you were asking about total sound quality, you might get better quality out of your main speakers. Due to the plate amp having a passive highpass filter (most of them do, check yours) in the speaker thru terminals, by rolling off the low bass from your mains, they will have less work to do. And, as a result, they should produce less distortion and sound better.

HTH...
