I have some hiss and noise coming from my mixers into my souncard, I was wondering if there's some sort of "system" plugin or whatever (on Mac) to reduce noise.
Something like a noise gate permanently on the inputs, or something like Klevgrand Brusfri always enabled on inputs...Is there something like this on the market?
Thanks!
"System" plugin to reduce noise?

Izotope RX, Acon Digital Denoiser, Wavearts denoiser, Waves X-Noise just to name a few... You still have to put them the on track...

Thanks, but I was asking if there's something that can be set PERMANENTLY on the input of the soundcard, not only in a track in my DAW (logic BTW). I am searching for a "system" plugin or whatever we might call it 
(Sonarwork Reference has a system plugin, always active on the outs to calibrate the speakers. I need something similar on inputs)

Are you on PC or Mac? There's nothing I know of for PC but Mac has some tools from what I believe. Example there's this one:

Hosts au plugins. You could put a gate plugin on it.
Now...why is your mixer adding so much noise to your signal? How loud are we talking? Are you sure you don't have a ground loop or issues somewhere in your chain? If we're talking noise around -70dbfs, ok, that's just analog sometimes. If it's louder than that, you may want to start figuring out where the source of the noise is and see if it can be remediated before it hits your mixer or PC.
Also, can't you just mute those channels when when you're not recording? Or if your soundcard has a software mixer, bring down the mixer channel volume when you're not actually recording? I have a bunch of stuff plugged into my RME Fireface, but I use the Total Mix software to keep unused inputs out of the analog output when they're not in use. There's no point in hearing channels you're not actually trying to monitor.

Thanks for the hint, I am on Mac, I see that "menuBUS" is no longer neing developed but the developer now works for RogueAmoeba and created "SoundSource", which does similar stuff and should be able to load AU plugins onto System Audio. I am gonna try it.
I have 5x Behringer RX1602 that connect their stereo outs to an old Roland Line Mixer. (ch. 1-2 first mixer, ch. 3-4 second mixer and so on)
The noise is not "ground loop" nois, it's just a simple hiss, not really loud. At normal/low volume, it's barelay audible, but when I want to mix something at higher level, it becomes noticeable. The solution so far is simply t omute the channels I am not using (I don't always use 40 synths at the same time )
I have mitigated the hiss by setting full volume on the synths, full volume on the RX1602s, and keeping the gain on the Roland at minumum.

I'd guess you've got a problem in your mixer. Perhaps one of the inputs is not behaving well?
Go through each input 1 by 1 to find the noise maker. Mute all other tracks/channels. Then it's just a matter of treating the problem. Grounding problems can cause noise issues too and not just 60hz ground hum, it can actually cause full on EMI and RFI noise.
Most modern mixers should be close to dead silent, especially digital mixers. Also check your cabling from each synth to the mixer, a bad cable can certainly add noise. Also check your cables from your interface to the mixer.
I'd suggest turning up the Roland, and turn down the channel or interface input.
You really want the input as hot as you can get, this will reduce noise. And of course be careful of any distortion or guitar effects, they are notorious noise enablers.
Tracking down noise issues can be painful, but so worth the time invested.
Good luck,
Dirk
