Which DI design for guitar pedals in AUX loops?

[Sheriff]

Hi!
I've searched this and several different forums but need some further guidence.

I'm building a pedal board for my guitar rig, and I'm going to build a DI system so I can use my delay and reverb units as post effects in AUX loops on my recording interface (Maudio 2626) (Bal. line level out, mic pre input)

I need some help to find the right design for this application. I've would prefer building an passive DI to keep it simple and small and I've looked into jensen designs. When inserting the effects to the instrument input(active DI, 1Mohm) on the 2626, I get a decent signal.

1) Since I can adjust the send level, do I really need an reamp box or attanautor in front of the effects?

2) I need to split the send signal to three units, and I have an active Axess Electronics Buffer/splitter, which is designed for High Z outputs. Is it better to use an passive splitter? (Like: http://www.jensentransformers.com/as/as013.pdf)
And what affect will it have on question nr 1?

3) Will a passive simple transformer based DI do the job between the effects out and mic pre input? Or do I need an higher input impedance like in an active DI? (The DI input I tested had 1Mohm impedance)




Thanx for all help

Hi
I'm no expert, but:
1) you'll almost certainly be ok without an attanautor in front of the effects

2) active and passive will both work v well - the choice is subjective. If you have the $$$, a high-end passive unit is attractive
No effect on Q 1.

3) a simple passive DI can do the job between the effects out and mic pre input. Tho watch out for cheap ones that attenuate low lows and high highs.

1M input impedance is high (perhaps too high if you are using good quality cables).
