DDT compression and do I need it?

  1. Hey,

    I have a Peavey mark VI Bass head. for all the years I have had it I always followed the manuals instrutions to leave the DDT enabled to protect my speakers. Does anyone know exatcly what this does? I am running an 8ohm EV 4X10 and a Old 8ohm JBL cabinet. I dont always use the 18. In fact if shutting off the ddts will help me get a little more volume I'll probably drop the 18. I am going to experiment at rehearsal tonight with disabling it, but I'd still like to know what exactly it is compressing..

    if it's protecting the speakers, it's probably a clip-limiter..

    I think it's current limiter in the power amp realm.
    I had Peavey Mark VI head as well. I operated it both ways with DDT in and out. Sounded really good too. As I recall, shutting down the DDT did give it a bit more balls but it did break up a bit. Use your ears see what you like. Of course, I could be wrong.................

    I used to own one of these. However, Trip, I didn't think it sounded very good. Now I use GK!:D

    Yeah, it's just a power amp limiter. I thought that it squashed the sound too much, but then again most Peavey amps do that anyway without the DDT compression.

    Sulphur La,
    I play GK myself these days.;) :D I am one happy boy!! I really do recall the Peavey sounding pretty good though.
  6. Well, I shut it off and didnt really notice much of a difference.. but then again when it was on it was'nt really coming on. I think it is a peak limiter on the preamp section. When I have the pre cranked up, thats when it comes on. Tonight I Cranked the main up to 8 and left the pre @ 2, sounded better.

    I am looking for another amp, shopping a hartke 3500..
