The professional way to do this, is with a DI box. I think these are the best:

But in a budget, an impedance marching transformer will do the trick:

Edit: didn’t want to leave out the a solution.

It'll work in a pinch but it is not technically correct; what you're describing requires a balun, it's a matching transformer to connect your unbalanced end to a balanced connection.

You should still use a shielded cable, the 'green' goes to the shield to prevent interference.

Is your impedance matched correctly? What is the actual microphone you're using? You may need a circuit which also matches impedance. Here's an example.

You can also get a USB adapter for standard vocal mics, like this one:

There may be a mismatch between your standard vocal mics and your sound card, possibly an impedance difference. Are you plugging them into a mic input or into a guitar/instrument input? The latter are high impedance and most vocals mics are low impedance; you can get an inline matching transformer if that's the case.

I see what you're talking about. I'm not so concerned about noise as I am about doing this in a weird/hacky roundabout way.

Why stereo? I get that it's nice, but you're going to double the number of buses used per channel, which seems pretty wasteful.
Or to put it another way, it makes more sense to have 16 completely separate monitor channels than it does to have 8 stereo channels and probably end up sharing them. The logic being, if you're running a large enough event to require 8 monitors, you'll probably eventually need more monitors or buses. It can be a major pain to re-route everything to make it work.


If you do somehow have 16 buses to spare, run them all into passive DI boxes via a gender changer adapter or cable (https://btpa.com/MIC3-XX.html for custom length female to female xlr) and use a TS 1/4in to 1/4 TRS (aka insert cable) to get your individual mixes. This usually works for passive DI boxes, almost never works with active boxes. You'll be buying 16 DI boxes (and probably a couple spares), 16 female to female XLR cables (and probably a couple spares) and 8 insert cables (aka 1/4in unbal to TRS, probably at least 1 spare).

Or, the other route is to use the Shure a85f in-line inpedance matcher (or similar) to get your XLR channels to 1/4in TS https://www.amazon.com/Shure-A85F-Transformer-Female-4-Inch/dp/B0006NMUHW, then use a Y adapter to get to TRS https://www.amazon.com/Hosa-YPP-117-Stereo-Breakout-Cable/dp/B000068O54
I didn't bother to spec anything nicer than Hosa cabling here, you probably should look into something nicer if this is the route you take.

You can also try not using the DI boxes and losing the impedance matching. Sometimes this works, sometimes it doesn't. Hard to tell on paper if you'll get away with it. I'd personally try one channel worth this way and if it works roll it out to the rest. It's a much simpler, single cable setup (although technically "wrong"). BTPA.com and others will make you custom cabling, and if your order is pretty large they'll work with you on price if you ask.

Yea you could just use the line out (or even the headphone out if you take care with gainstaging) and send that to your mixer. And send the guitar to the mixer. and then have the drummers headphones connected to the mixer instead of the interface.

I have done a similar setup once and used a simple behringer amp sim pedal to create the scratch guitar, worked fine. We had the guitar and the bass playing on headphones live with the drummer, but only drums in the room were recorded. If it is any type of authentic rock then I'd listen to steve albini and try to make the band play together live anyway, for a more natural result than overdubbing everything. But that's a completely artistic choice at that point. Theres no one right way to make a good record I guess.

As for the DI- solution, no idea, I don't have a DI 100, you would have to try and listen how it sounds and compare it to a real mic input. I'd maybe try to get a low-z to high-z adapter though, something like this: https://www.amazon.com/Shure-A85F-Transformer-Female-4-Inch/dp/B0006NMUHW

Howdy partner.

In addition to the Balanced vs Unbalanced issue, the other issue is impedance. Pedals are designed for High Z inputs. You would need a device like this: Shure A85F Transformer; Low Z, Female XLR to High Z 1/4-Inch Phone Plug https://www.amazon.com/dp/B0006NMUHW/ref=cm_sw_r_cp_apa_i_UJTtDbTBKTBW2

This would make sure you have a good damping factor which in turn will give you good signal.
