Do I really NEED a DI box for synths?

If I am using the 1/4" input on my Vintech 1073 or us an XLR to 1/4" adapter to get a signal into an XLR only pre, do I need to use a DI box?

Please, I need actual technical advice.

If I JUST have a mic pre with XLR inputs, but my synths are 1/4", do I just need adapters or a DI?

Please advise

My actual question...

Beyond the philosophical Yoda advice, do I NEED a DI box if I am then running keys into a pre-amp, like an outbaord set of SSL pres?

What does that do, not do, is needed, not needed? Or is this just an 1/4" to XLR adapter issue?

Please, some actual ifno would be great, please. Really.

If the preamp isn't seeing the impedance it wants to see, the synth won't tend to sound right, mostly frequency-wise. Use a box.

Generally, if your pre has 1/4" inputs on the front panel, like the vintech, you don't need a DI. Just plug into those. But if your pre only has XLR mic inputs you'll need a DI.

But it might still sound pleasant. It may be "distorting" in a musical way.

I just bought a radial Passive 2 channel DI just for that purpose and it works amazingly well.

Easy answer. Try what you have first. If it doesn't work/sound right, then you ask this question.

I've used preamps for synths a lot because my patchbay is balanced only and I don't have balanced synths. I only have a sansamp bass DI so I routinely use DI inputs or the regular mic inputs on a preamp. works for me, though I don't think having a stereo DI is a bad idea.

that's exactly the point: the only *actual* info that matters is what actually works, and the only way to figure that out is to do it yourself.

you're on the high end forum, you've come to a place where we blather on about how this $3000 compressor is less musical than that $3000 compressor, and we can only do that with authenticity when we've used the things in question. what will probably serve you better, here on this forum and in your studio, is to simply do the things that you are curious about and ask your questions based on your experiences.

we can tell you yes or no all day long --- and honestly the answer to any question here is always 'yes', 'no', and 'it depends' all at once --- but ultimately you still won't know until you do it. the reason most of us advocate this approach is that it will eliminate the need for you to continually rely on 'experts' for information which is generally available to you anytime, all you have to do is be willing to try things.

we're a helpful lot, you'll find us even more helpful when you meet us halfway.

The outputs of your synth are instrument level (should be anyway).

The XLR input of a pre-amp is usually mic level.

The 1/4" input of some pre-amp's could be either line or instrument level.

You should find out what your plugging the synth into first. If your pre's have an instrument level input then plug your synth into that.

Plugging your synth into a mic or line level input isn't going to sound "proper". This is what DI boxes were made for. That and making long runs of un-balanced signals.

I would already recommend using a DI box for unbalanced synths simply on the basis of reducing RF interference, mains and grounding hum - the sonic benefits of a good one are an added bonus.
