    I have a Peavey TNT 115s that has a "Power Amp In" option on the front panel.

    If I connect a power amp through this, will it disengage the power section of the Peavey and allow me to run the 115 speaker with the connected power amp? Basically use the combo as a speaker cab only.

    Thanks for your responses.
  2. NO, that is the input jack for the internal power amp. You'd use that if you wanted to connect an external preamp up to the power amp instead of using the internal preamp. It does not break the poweramp -> speaker connection.

    If you want to use just the speaker, you'll have to add a speaker jack to the speaker cab because I think the speaker is hardwired to the internal power amp. You'll also want to somehow disconnect the internal power amp from the speaker when using it as just a speaker cabinet so as not to backfeed the amp and fry something.

    No. The "power amp in" jack is for the output of a separate preamp feeding the power amp and speaker in your combo. There is also a "pre amp out" jack which whill use the peavey pre and feed the signal to a separate power amp.

    Thanks Throbbinnut & Metron.

    I had a feeling I would not be able to do this.

    DO you have an old TNT or a new fancy one with all the red borders on the head? Because i know for a fact that on my old (80's) TNT, the wire is soldered, therefor i cant bypass the head.
