Just got my binaural mics and want to try them out but haven't been able to get the necessary Y cable yet. :mad:

So I'm going to re-install my SoundBlaster Live! 24-bit just to test them out because it has the appropriate 1/8" jacks.

So my questions are:

1.) Is the line in jack stereo? If not, is the mic input stereo?

2.) Can I just disable the M-Audio soundcard I have now in the Windows Device Manager? Without having to completely remove the card? This way I can install the Sound Blaster too and switch between them by disabling/enabling one or the other?

Thanks.

Once I get this working I'll post some clips for you to hear.
 
mic in is mono. line in is stereo. i don't know how well enabling/disabling thru device manager will work.

You sure the line in is stereo?

I guess I'll give it a shot and see what happens. :confused:

how?

a single input cannot be stereo to my knowledge.

it may be balanced but thats not stereo.

hmm. maybe i am missing something here..
 
now that i think about it, maybe it can be.

by usinga balanced cable and using the second conducter as a separeate mono signal, you could have stereo.

i guess thats like the audio out to the speakers??
 
cables aren't balanced. circuitry is. a trs cable can carry a mono balanced signal or a unbalanced stereo signal.

an 1/8" soundblaster line in jack is a stereo input. i think it's left signal/tip, right signal/ring, ground/sleeve.
 
Yup worked fine. :cool: I Got both cards in there right now and I can switch between both pretty easily through the device manager.

And you were right. Line In is stereo. Mic in isn't.

I Need to get a Y cable so I can hook them into the preamp. Otherwise the volume is pretty low (around -30db).

I recorded a couple things, so maybe I'll post some clips later on.

Thanks again.
 
Oh one more question.

Do you think I could get a Y cable that goes to 2 1/4" mono's? And hook them into the "direct in" of the preamp? (DMP3)

Or would I have to get ones with XLR's and hook them into the mic ins?

Because it will be hard to find a 1/8" stereo female to 2 XLR's

bingo....think of a headphone cable, Tragik. It's stereo.

The direct in is for Hi-Z inputs...not line level.
You could get a Y cable with 1/4" on them and then get a 1/4" to XLR adapter. Or just buy the connectors and make the cable yourself.

Are there any specs on those mics somewhere? Did it come with a manual saying what it puts out?

It came with a manual but it doesn't say what kind of level it puts out.

They're meant to go into portable recorders in either the "Line In" or "Mic In" jacks.

It says they are powered by "plug in power" or 1.5 - 10 volts DC.

I bought the little battery module to power them.

Hey, danny! Check the Cave already! Belated b'day thread in your honor already! :cool:
 
yeah, we chatted about it earlier. It still bugs me that it says:
If your recorder does not provide a bias voltage or if you want to feed your recorders line inputs to avoid overloading your recorder's mic pre-amplifier, you can use one of our Battery Modules (check out our Battery-Module Section).

But apparently it's not putting out line level.
:confused:

---edit---
I copied the wrong statment, oops...fixed

Battery Modules will power the microphones with optimum power ( 9 volts D.C ), increase dynamic range and enable the mics to handle higher (SPL) sound pressure levels ( loud sounds ) without distortion.

kind of makes you wonder what the 1/8" out cable on that battery box is for huh?
 
Yea I e-mailed them and asked them what level it puts out.

They've been real helpful so far and the mics seem to work pretty good. Sound quality is real good. The "binauralness" doesn't really seem to be there as much as other binaural recordings i've heard.

Sounds about the same as when I recorded in stereo with my omni directionals.

Oh well.

I really need a dummy head or something so I don't have to wear them.

Any ideas for that? :confused:
 
a few suggestions:

myhatbroke

ford van

a cardboard box
 
Hm, don't want MyHatBroke...

I'll need some fake ears or something because i heard that the binauralness really comes from having the mics in the ears...

So I need prosthetic ears? :confused:

Duck taped to a cardboard box? :confused:

How ghetto, but if it works...

But where do i get the fake ears? :confused: :confused:
