I want to know what is the best way to split my live room signals (mics, lines etc...) so I can feed my analog board and my digital interface simultaneously? 

I'm shooting some music instructional videos in a residential home basement. Due to problems with mic bleed, I've convinced the subject to wear headphones for listening to himself, and his assistant musician during the shoot as opposed to speakers.

I started recording using a 2-channel audio interface. If I connect XLR Y-splitters to each input, will there be loss of signal strength or any other odd happenings, or can I assume that I'll be able to get 4 inputs of the same quality as original. I realize it won't be 4 separate channels and just 4 inputs, 2 channels.

Mic Splitter box, any recommendations? I want it for comparing various preamps . Would this work: pro/ cons?

Here is the deal, I am picking up a very nice 8516b on monday, the rest of my set up is saffire pro 40, digimax fs, la 610 in to pro tools, 2-bus lt and monitor st on the other end.

Just finished reading "Behind The Glass - Top Record Producers Tell How They Craft The Hits" by Howard Massey. Fascinating read... Massey interviews 37 producers/engineers.

In an interview with Mick Glossop (Van Morrison, Frank Zappa & many more), Glossop says...

An electronic device that consists of a Radio Frequency (RF) signal splitter, preceded by an RF amplifier that compensates for the RF loss of the splitter. Used to allow one antenna to feed several receivers.

In wireless microphones, a device that divides an RF signal into two or more equal signals while maintaining the desired impedance at the input and outputs. For live audio applications a splitter functions in much the same way for providing signal feeds to both the console and to a recording device.

I was using a friend's mixer to route my output signal to powered monitors as well as to a standard home stereo. My friend needed his mixer back. Is there any budget alternatives to listen route my signal to the monitors and to the stereo speakers? Somewhere around $50 USD?

Some kind of Y-cable?
Line-splitter?
Monitor management device?
Some kind of aux-box?

What I'd like to do is this:

I'd like to mic my amp cab and go direct at the same time for coloration. I have a PreSonus Firestudio Project. I'd like to see what my options are for either purchasing a line splitter or if there is something else on the market than can achieve the same goal.
