Ken,

I don't have that particular sound card, but I've used ETF and R+D with many different sound cards including an external firewire model (Presonus FireBOX). What sort of help do you need?

You may want to drop them a email to see. I have a $1000 motu and it would not work. Was forced to buy a $70.00 sound card to make it work.

I've used it with ETF, but I haven't really played with R+D yet.

Hi Guys...

I have a laptop, a mac at that running XPsp2, but that is for another thread.  Anyway, I read somewhere that I could use this usb adapter...I watched the videos but I am not totally sure what I need to plug into where...  So this USB box has phantom power so I can use the  Behringer ECM 8000 as a Mic.  But I am not sure how to hook it all up and test/normalize it.  I have the USB cable that goes to the laptop.  I have the mic cord that goes to the Mbox and then I have to go to the amp inputs.  I have stereo line as an output as well as mic size outputs, right and left.   

So do I get a cable that is stereo mini and RCAs and plug that into the amp to have the software play a tone?
Sorry for the silly questions.

Thanks,

Ken

There are three things going on with wiring:

1. Mic cable going into mic input #2 on the back
2. the loopback cable (simple 1/4" mono to 1/4" mono cable) connecting the channel 1 unbalanced output on the back to the channel one input on the front
3. 1/4" mono to RCA cable from the channel 2 output on the back to your receiver/pre-amp

If you want to send the signal to both channels at once, just put an RCA splitter on the end of the cable in item #3.

ok, great, now off to get cables and mess around a bit and then I can post more stupid questions.....

Thanks!!!!

Brad gave you the right answers, and the drawing below is derived from a graphic buried too deeply in the ETF help file. Also, please don't apologize for asking "stupid" questions. They're not stupid at all because the hookup is not obvious and the suppied docs do not spell it out clearly enough. It's not you, it's ETF author Doug Plumb.

Ethan,

Totally agree. When I was hooking it up I was saying to myself the whole time "This can not be right  ", but it was. 

I really wish ETF was a little more plug and play then plug plug  unplug replug.

You guys are too funny...It didn't really make sense to me....But that's what the list of for!

Ok, off to radio smack.

Ok, so baby steps...I need to take a reading first by hooking up the Right and Left channels inputs to the outputs.  I don't really see how to do this.  That seems strange but I see ch2 inst/line and a stereo mic on the back as well as the Ch1 and Ch2 mic inputs.  The easy part seems the outputs, the 1/4 R and Left.  I am not sure what to do, 1/4 Right OUT to what??? and 1/4 Left out to ???

I tried stereo mini to stereo mini from Stereo Line (Output) to Stereo Mic (Input) and it didn't work.  What I am getting is a crazy wave, not a flat wave with a spike. 


Thanks,

Ken

Kem,

I don't have that sound card, but looking at the photo you posted earlier:

Connect a 1/4 inch to 1/4 inch mono cable from the 1/L Line Out on the rear to the Instrument Input on the front.

Connect the 2/R Line Out on the rear to a Y splitter, and in turn send that to Left and Right line inputs on your receiver or preamp.

Connect your microphone to either the XLR or 1/4 inch Inst/Line Channel 2 input on the rear.

Dear Ethan,

Thanks for taking the time to look at it.  I think that I will contact the software developer because I think that I need to have a calibration file saved of the mobile-pre's noise or gain, I am not sure what you call it.  I do know in the instructional video you plug the outputs to the the inputs and run a signal and that data is saved then the software uses that as a base line.  I don't seem to be able to get that part hooked up right.  The mobile-pre seems to work as I can hear computer noises thru my speakers.

I will let you all know when I get it going.

I plan to do a full report on my room with no treatments and start treating it and posting graphs (from RPlusD) and photos.  I have been following room treatments for quite some time and I have no real knowledge in this area.  I figure if I can do it then anyone can!  It seem that so many people have benefited from treatments, from all the major manufactures including the DIYers.  Now that I have a better room I with acoustic problems I want/need to address these problems.  I am on a budget and this mic, software and usb audio box have already set me back a few $$$.  I wanted to do just more than buy a few panels and stick them up.  I wanted to see how moving them around would affect the sound and see it on a graph.  This is an apartment and I plan to move many times over the next few years.  I feel that I will keep up with room treatments so I will need this gear, at least that's what I keep telling myself.

Thanks,
Ken
