Default Balanced / Unbalanced

I have done numerous searches on the internet and read all of my Owner's Manuals and I can't find any mention of this particular situation. Can someone please help.

What happens when someone uses balanced cables through their whole system, but some of the equipment uses balanced input's and output's while other equipment uses unbalanced input's and output's. Everything is still connected with balanced calbes though regardless. I run the signal chain like this: Balanced cables out from my PreSonus Tube Pre Amp(which has balanced in's and out's) and in to my HHB Radius 3 Fatman Compressor (which also has balanced in's and out's). Next I run balanced cables out from my Compressor and in to my Antares AVP-1 Vocal producer (which has unbalanced in's and out's). Finally I run balanced cables out from my Antares AVP-1 (unbalanced in's and out's) and in to my Digi 002. Is there a serious problem with what I'm doing or is it okay. I know that Unbalanced Cables are splitting/flipping the signal into a + and - which creates phase and cancels out any noise that was introduced into the audio signal path. What I am wondering about though is if interconnecting all my balanced and unbalanced in's/out's with balanced cables is messing with my audio signal in a way that I don't know about. Will I only be recording half of the balanced connection (the + or the -) once it hits the unbalanced connection? Or does that not get affected? I've read that additional noise might be introduced. Will I be overloading an input because of the -10 and +4 difference? I really don't know what kind of problem this might pose so I wanted to learn about it now before I spent too many hours recording with a bad signal chain. Any help or guidance will be greatly appreciated.

Well, if possible def run balanced connections. They are quieter..,signal to noise wise. It means its grounded pretty much. What your doing isnt horribly worng or maybe evan noticable audibly. You wont be overloading going into your -10 or +4 inputs. Its like you said pretty much just takes care of unwanted noise picked up along the sound chain.

Hope this kinda helps.

running balanced outputs connections into an unbalanced input or vice versa floats the neutral, which can induce noise and reduce overall signal. It is best to run balanced cabling only to balanced connections. ronnecting an unbalanced and balanced connection unbalances the line, and it is best to run unbalanced cabling to these.

Balanced/unbalanced connections and input sensitivity are not related. However if you run a +4dbu singal into a -10dbV input you WILL overload the input. there are many devices on the market to convert -10dbV to +4dbu and vice versa.
