Is my amp Okay?

icecoolwas · 1st December 2008, 10:46 PM

Well I've connected my Amp to 12V 33A (In my house) through a power supply and Im using a rca to phono lead (headphone jack) then to a Headphone splitter, I heard feeding the amp from a headphone jack is bad, and I should use a crossover (a crossover is?) Is this a loud of.. you know what or is it true?

Thank you

Is there any chance you could rephrase that? It is hard to follow what you mean.

Well I've connected my Amp to 12V 33A (In my house) through a power supply and Im using a rca to phono lead (headphone jack) then to a Headphone splitter, I heard feeding the amp from a headphone jack (straight from the pc or any device) is bad and can mess up my amp, is this true?

Thank you

I dont see any reason that feeding the amp from a headphone jack would hurt anything. I've done it 100s of times on all sorts of gear. Never a worry.

You may get a higher level out of the headphone jack than normal, but just start with the amp volume down low to be careful.

Uh, well, no. The power supply didn't make sense, tho.
The "In my house" should have tipped me off, yeah?

Sometimes I'm just plain slow.....
