4. You need an interface with an insert point.
5. Learning and understanding the differences between:
Balanced and unbalanced
Will save you from spending money on equipment that's not compatible with each other. Downloading manuals on gear you are considering purchasing is a good idea as well.
thanks so much to everyone for the input
I get that the motu 8pre is designed for low impedence mic level....but I decided to experiment tonight with the following signal path
Mic INTO cheap preamp (tube ART) INTO compressor OUT OF compressor INTO motu
I know this is going against the advice offered in this thread
The mic was an AD 2020 which I was experimenting with as a drum overhead
The way I worked it was the preamp perameters (gain/output) were at like 75% output
The gain on the compressor was at zero
I had the gain on the Motu preamp at zero; and I also had the -48 decibel (or whatever it is) engaged on the Motu; so effectivle the motu is adding no (or as little as possible) gain to the signal
The diodes on the motu showed that the signal was in the green and not clipping
The first thing I noticed, was that that the signal on the daw was BLACK...ie far thicker and blacker than ever i'd seen
Normally I can isolate individual snare/kick hits on the visual representation of the signal in cubase, but this was just a thick fat black signal......not sure if this is a result of my efforts at compression, or because the signal was turned up quite high on the pre amp....will a/b with out compressor later....I felt good about this because I figured this would = loudness, come mix time
On the play back I was very suprised to hear the detail I had captured.......I could really here the toms resonating in the mic (which is positioned over heat at roughly head-height (standing)...I could here myself humming away to myself as I was drumming....seemed to be a lot of life in the audio, and everything seemed louder than anything I was used to before....
However i did feel that tonally the audio seemed a little brittle
anyway another friend told me that if the final part of mysignal path was line out of the compressor in to the MOTU, then I would be back to line level going into the motu....I think he meant that the xlr leads are carrying more of a boosted signal........
will try to attach mp3 when i figure out how
