DI on a board? Why not use the one on an amp?

    Hi,
    Often I read stuff that's similar to this:

    " I want all of my effects to affect the front of house sound so I always have my DI at the end of the chain"

    I'm thinking ok, fair enough, Then I look at the micro VR sitting behind me now in my office and I see a DI. The other day I was at "club soda", a pretty big place and I spotted this on stage:

    ampeg.jpg

    I went and asked the sound guys why that was there and they replied, it's his DI ..

    Yesterday I saw some great NAMM pics from the guys @Darkglass with an Aguilar TH 500 in the background.. it also has a DI.

    So I'm thinking, I like the sound of my little ampeg, right now, it's my sound. Someday I'll grow a pair and get a TH 500 or something and I'll like the sound of it, when that happens that'll my new sound.

    So question is, Why would you use a DI from a pedal instead of the one on your amp? Pardon my ignorance, I've only played twice on a stage, so I have a lot to learn!

    :meh:

    I usually use the DI from my amp, but I always keep a DI with me. If the amp goes down, I can still DI to the PA. If all you have is the DI in the amp, if the amp dies you are left with nothing.

    I am with you, never really saw the logic, for myself, of a DI or pre on my board. I use my amp's pre and DI. But I do bring either another amp or a Sansamp as a backup.

    Lots of reasons for choosing DI placement. Could be that the amp DI is pre EQ and they want to dial their DI tone from a pedal. Could be that the amp works better running through speakers and when sending a signal to the soundboard they might choose a DI with some kind of speaker simulation.

    My SVT 4 Pro has a DI and I use it, but once in a while it buzzes like crazy (certain venues). I then use the pre-amp out to my handy passive DI box (plan B) kept for just these issues.

    Edit; There is no ground lift on the 4 Pro's DI output (my cheapo passive DI does however and that fixes my issue when present) so I think the 4 Pro would have benefited from one more simple spst switch (a ground lift switch)...

    Not all amp DI's offer a pre/post-EQ choice, which can be big. If you have to add a lot of treble or mid on stage and that can't be bypassed for FOH, you run the risk of sending the sound engineer a signal that he may not be able to work with as easily. I prefer a discrete DI for that reason mainly, but also because I like the 'flavor' of certain DI's and know how they will impact my sound. Plus, as was already mentioned, if the amp dies, the show can go on!

    If I'm using a supplied backline, on a travel date for instance, I don't want to question what kind of DI will be available. Having a simple, great sounding, no-power- required, passive Radial JDI at the end of my board is a safety precaution. I always know that I'll be able to get a great sounding signal to the board.

    Micro VR's DI is pretty good if you don't crank the gain super hard. Tends to run hot and adds distortion if you do. I use an outboard DI because it's better ;) but I've used the Micro VR DI on occasion and it's as decent as any SS DI.

    I think I understand, but then what you're saying is that your amp is not really part of "your sound" when you have something like this at the end of your board?

    Sometimes it's impossible to remove the noise from a bass head's integrated DI. It depends on the quality of the head and how carefully it's DI is designed. MANY integrated DI's are nothing but an afterthought and perform quite poorly. A good quality stand-alone DI unit, whether it has a preamp or not, can be a lifesaver in some situations. For some having a preamp that is integrated as well also opens up many options, particularly if they play passive instruments and want to goose bass and treble a bit to add a little more flare to the tone.

    I'm in the last group, playing mostly passive instruments. They sound great already, so having a good preamp that can lightly alter that tone is a huge plus. I can throw it in my gig bag and have that tone anywhere. It kills ground loops also, which is great. For me, since most of the time I'm playing with IEM's and not an amp, it helps me get a consistently great tone that is familiar to me most anywhere I play. As others have said, they tend to be less likely to die on the gig as well, so you have a safety net.

    IMHO, a good DI is a must have tool that is always with you.

    Oh Jimmy! Please explain, can you get an ampeg soung with an outboard DI ?

    And actually I think that's the real question there.

    Mainly correct. Depending on the size of the venue there will still be some "stage bleed" from your amp. But the PA will have none of the amp sound in it.

    I played a gig where the soundguy was very reluctant to use my amp's DI output. Yes, it was a CRATE amp. No problem, I whipped out my SansAmp bass DI and used that for the soundman's feed, used the parallel out to feed my amp.

    The SansAmp or a Countryman DIs are 'industry standards' and sound guys like having something they're familiar with.

    Or musical theatre gigs as well. Church and Pitwork are primarily the reasons I rely on everything other than the amp for my sound.

    I can with my DI...A-Designs REDDI. It was inspired by the B-15 and sounds like a B-15 being speaker level DI'd when you give them both the same EQ.
