Schiit SYS Passive Preamp

  Hello~
Can I connect it like this?
Modi > Sys > Power Amp > Speakers
or do I have to buy a preamp to use the modi with my power amp like an Asgard 2?

Yes! Exactly as you have above!
 
Basically anywhere you have RCA connections, you can passively adjust the end volume via the Sys. It's a great little box, which does not alter the sound signature, only the volume

I use Sys in the same way. Mine is a little more complex as you can see below. But basically same idea.

Hey guys, happy new owner of a Vali 2 here. I heard that I could theoretically use a SYS in reverse if I wanted to use both my Vali 2 and a Magni 2 with a Modi 2 DAC and switch amps depending on my preference. My question is, how exactly would they all connect "in reverse" with the SYS?

Plug the Modi into the output of the SYS. Plug the Vali and Magni into the inputs. Done.

One thing to keep in mind is that it wasn't designed for this and you lose the use of the volume knob. For me that volume knob was important (matching was a bit difficult between the amps) so I bought this:

And that one is designed to actually perform the task, so it has more options like switching off one signal to the amp :)
 
And, if you're in Europe it's a lot cheaper as well :p

Ah nice, thanks. That looks to be a bit overkill for my needs though. Just want to be able to switch between Magni and Vali without swapping cables every time. Does the SYS attenuate some of the incoming signal from the Modi?

I believe not because you have to have the volume at max for it to work properly.

Out of curiosity: why is it overkill? It doesn't have that many functions :grin:

Well, true. Probably just too many functions for me.

For starters, it has its own headphone amp! Not to mention all those XLR jacks, I don't (yet) own anything that has XLR plugs. Perhaps I'm just trying to justify not spending any more money, outside of a Schiit stack, haha.

I forgot about that one, it won't work in passive mode (aka no power plugged in) which is how I have set it up. The headphone amp is more of a gimmick though if you ask me. The rest of the unit doesn't need power as it's completely passive.

The xlr is a bit odd I agree but that's because this is a professional audio device, I solved that by buying some xlr to rca cables from thomann.de. Studio grade microphone cable for not much money with neutrik connectors, work like a charm!

And this would replace the SYS preamp as the cheaper option (at least in Europe, can't check other parts of the world) while being more fit for your use case.

Admittedly, the SYS is prettier of you have the complete stack. :wink:

Certainly! It's $225USD here in USA, so it's a little out of my budget, but I might actually have a friend that could benefit from this. 
 
As for myself, yeah, I'll keep everything in the Schiit family. Haha!

Can someone comment more about how using the SYS in reverse removes the volume knob's functionality? I am currently using it in reverse to switch between a logitech computer speaker set and an integrated amp, but will be soon getting a power amp. I was planning on just hooking it up to the SYS and using it as the pre amp, but if it only properly works in reverse with the volume all the way up I may have to find a different solution.

Not following you.  I used the SYS as a preamp.  It worked great 2 in 1 out.  Now I use it as a switch with my VALI 2 as the preamp between it and the amplifier.  Does that answer the question?

I use mine in reverse, with my DAC going to the output and my logitech system and my amplifier hooked up to the outputs. Others previously posted on this page that running it this way makes the volume not work properly unless it's all the way up.
