Connecting Sennheiser e935 up to a computer.
« on: January 23, 2011, 05:11:36 pm »
Help, I don't know anything about microphones.  

My step-son left his Sennheiser e935 microphone for me to play with.  The Sennheiser says it's a dynamic microphone, so I think I can just hook it up to my computer.  All I need is a 3.5mm stereo jack to XLR female cable.

Is that right?  Thanks!

Low to Hi Transformer with 1/8" plug

There is actually a transformer in the XLR connector.

Usually you see them as XLR to 1/4" like this. Then you would connect your desired cable, be it 1/4" to 1/4" or 1/4" to 1/8" or whatever.

Thanks TB!  I put a cable on order.

So, the low impedance mic needs a transformer to match the high impedance of the computer card.

That is correct. The fact it is dynamic means you don't need to power to it but you have to match up input / output levels.

I need some more help.

I hooked the microphone to the computer, and it works, but the signal is really low.  I turned the volume up on every software dial I could find, but no luck.  Tried the microphone jack and the line-in jack, no luck.

I think I need a pre-amp.  Thoughts anyone?

The input signal is low. Even using an audio interface to run through, i find my input signal on my shure sm57 is low. What you need is a way to "normalise" it once it's recorded. I don't know what software you're using to record. But in Reaper, you can right mouse click on the recording and go to Item Processing and select "Normalise" and it will increase the volume of the wav file without causing it to distort or change.

@Ragz,

I'm using Audacity and it does allow me to amplify/normalize the recording.  But, there's hardly a "squiggle" on the level meter when I record and I have to amplify/normalize 30dB (1000X) to hear it.  I'm sure I'm losing some signal "quality" when I do that.

I think you are correct. If the PC won't do it you need something else.

are you sure your mic input level is high enough on pc? I had to raise it + add a litle boost (standard option of the on-motherboard soundcard of my pc)

Yeah, I'm sure it high enough.  There's a software microphone boost and that's on.

I'm beginning to wonder if it's just my inexperience that's the problem.  The mic is fairly loud if I speak right into it. 

I would have thought that it would have been more sensitive.

Just out of curiosity, the plug that plugs into your PC, is it Stereo ( Tip, Ring, Sleeve ) or Mono ( Tip, Sleeve )

If it's Stereo, pull it out one notch. Does the signal get louder that way? I realize it will be on the left or right only but is it louder?

It's a stereo jack TB.  If I pull it out one notch, I get no signal whatsoever.  If I record in Audacity in mono, it's not any louder.

I'm beginning to think it's the mic's character.  If I'm right next to the mic, it's okay.  If I'm 6 inches away, nothing.

Excuse me butting in, but did you get your impedance transforming cable yet?

If not, that might solve the problem.

It's a stereo jack TB.

How are you managing to get a stereo ..... plug. It's a plug not a jack for clarity.

with the sound you get, is it thin sounding and lacking body.
