class d amplifier line output advice

radams23j6 · 11th August 2011, 09:48 PM

I have a class d amplfier where the three outputs are used ie two normal stereo chnls out & third chnl to small subwoofer. Can i connect a line output from the the two stereo chnl ouput crossover boards safely or is there a better option, i want to use this to drive my external active bookshelf speakers which are not very sensitive but have their own tone controls. Any advice or suggestions would be "very much appreciated".

This is the area for forum problems, not audio problems. I'm sure one of the mods will move it to the right place.

If I understand you correctly, then no, you unfortunately cannot connect any line-level gear to the outputs of Class-D amps. (I'm sure it's technically possible - somehow! - in theory, but in practice it isn't done.)

And the power of the bookshelves cannot be boosted this way either. These simple things are surprisingly complicated

But I'm not 100% sure we're on the same page. I hope my answers make sense and are appropriate for the question
