AMPEG PF 50 how do you use the DIs live?

Discussion in 'Amps and Cabs [BG]' started by JWS, Nov 8, 2019 at 12:02 PM.

  1. Hi Bass experts,

    I have a new used AMPEG PF 50 in my possession and ask my self how do I want to "DI out" at the next live gig? How do you use it live?

    1. Both DIs simultaneously -> is there any chance for phase problems?
    Both DIs one pre the other of course with Level issues when i need to get louder on stage.

    2. Just the one after Powertubes...

    3. Just the one after preamp tubes ... post

    4. Just the one after preamp tube .. pre

    Endless options.. what are your experiences?
    Thanks for all your effort and expertise in advance.

    Greatings from Bavaria.

    Why do you need multiple DI sends to the front of house?

    So Anyway, I'd only send one signal to FOH. More than that and you're asking the FOH staff to spend more time with your sound than necessary.
    And we'd love to hear about Bavaria!

    As a general rule, send FOH pre-EQ. Many FOH techs/companies always use an external DI box before the amp to be safe, in which case you don't need the amp DI at all.

    If you don't change the settings on the amp during a gig, then you can talk to FOH about their preference for your other DI options on the PF50T.

    While your "awesome overdriven tone" may sound Great to you, the FOH may think not. Most likely they may think wth is this guy sending us?

    A few years ago I joined a soundman forum asking for advice and the gist was pre-eq DI was preferable with solid state and post-eq DI with tubes.

    I’ve never had an issue sending post-EQ to the soundman.

    If that forum is anything like TB...well, you know. :roflmao:

    It sounds like both you and the FOH people you work with know what you're doing. I'm not sure where you are, but out here FOH seems to like pre-EQ unless the cab is also getting mic'ed. What will piss them off is getting some wildly EQ'd feed that sounds good on the stage amp that they have to reverse EQ.

    I run our pa on gigs and always use the transformer out di. Sounds great coming through the pa.

    I totally get the clean D.I. to F.O.H. crowd here. However, the transformer out on these heads is friggin glorious. I have never had a sound guy say anything other than gushingly positive things about the way this head sounds. For playing 'bass' the PF50T is easily my fav amp.

    Some A-Hole tells you to plug-in. You do. Then you complain about the mix at the end of the gig. Not much more to it than that.

    Transformer DI out is the only way to go, trust me! That way the house gets the entire sound of the amp, and not just pre or post-EQ. But just remember that whatever you send to your cab goes to the house, so you don't want to be making drastic changes during a show. Knobs at noon is how you get flat response out of it, though, so when in doubt about your house sound, they're a good reference point for any sound tech to deal with. And make sure you tell the tech that if he gives you any static. I like to scoop a tiny bit of mid at 800 hz and reduce treble myself, but YMMV.

    Hallo JWS :)

    The tranformer D.I. is great! Use it!

    Why would you need to get louder? With a good monitor you should always hear yourself!

    => No volume wars on stage!!!! :D

    The "Pre" DI is the cleanest and loudest (in my experience).

    Seriously, that is THE reason to have that amp. IMO and whatever, but it'd be a shame not to.
