Wiring mic info needed

I just got a Senn ew100p G2 wireless system and I picked up a Senn MKE2-5 mic from eBay. I wasn't sure how to wire this to my stereo 3.5mm plug so I called Sennheiser. They told me the following:

tip = red wire
ring = blue wire (and he told me tie the blue wire to the shield as well)
sleeve = braided copper shield

I tried this tonight and I get no output at all. Can anybody advise what to try next? There are also two tightly braided wires (unshielded) that appear to be strain relievers and I crimped them in with the strain reliever. Help!

You may find that the 'uncoated' coloured wire needs heating up and scraping to reveal the metal.

If that is the Platinum version with the very thin cable then the wire will be that sort.

It looks odd if you are expecting standard wire with a rubber coat. This stuff has only a sprayed on coating.

Hi Jimmy. I was a little surprised at the strength of these wires. But, I guess they are built for durability. I was able to strip the insulation off with a little effort, but after soldering them onto the locking 3.5mm plug, I have NO output. I needed to find out this was due to my own screwup or if I simply got a dead mic from eBay.

Ummm, white? There is no white lead. Just red, blue, braided copper and two tightly wound stainless steel wires (non-insulated).

The white lead in mine was the ground, so use the braided copper wire instead. As far as I can see the other two wires are just for making the cable more rigid.

Use a multimeter and check he polarity and voltage coming across the wires. If you have the EW 100G2 manual it shows what needs to be connected in the technical specifications part.

Just a followup....in my zealous effort to make the connection more durable, I managed to crimp the cable clamp too tight and short-circuited the wires inside the jacket. So, it looks like THAT problem is solved. Now I have the problem of feeding balanced line-level audio into a consumer camcorder that only wants to see mic-level unbalanced audio. Any help on this?.....thread-cra**ing myself!!

Glad you got your wiring sorted . . the out level on the G2 can be taken down up to 30 dB in the receiver menu. If that still isn't enough, you can buy, make, or have made a line->mic attenuator cable.

I'm still struggling a little with whether the audio coming OUT of the receiver (AF Out) is balanced or unbalanced AND if it is coming out at line or mic level. Any clues?

Read the manual. Audio comes out unbalanced and like Abe mentioned you can attenuate the output on the receiver if needed.

Thanks guys. I'm getting this sorted out slowly. I guess I'm getting a little lost making these jumps from unbalanced to balanced and back again (when it enters my Canon GL2).
