Adapting Sennheiser G3 wired mics for use with Sony UWPs

Recommended Posts

I have a couple of Sony UWP wireless systems and I love them. However, I've found that the biggest downside to using them is that few rental houses carry mics wired for Sony. Here's my question: would it be possible to make an adapter that allowed G3 wired mics to be used on a Sony UWP transmitter?

These links from Sanken make me think that it is possible:

http://www.sanken-mi...index.cfm/11.25 (Diagram for wiring a Cos-11 pigtail for a Sennheiser G3)

The wiring styles are different (2-wire vs 3-wire) but it looks like the only physical difference in the wiring is that the ring and the tip are reversed. So just make an adapter that swaps the ring and tip signals, right?

Or is it not that simple? I suppose it usually isn't.

Anyway, any input would be greatly appreciated. Thanks!

My question is, why would you ever need the adapter? If you already have the UWP-V1 units, purchase mics for those units and have them wired for Sony. Pro-Sound, B&H and even Oscar Sound Tech will all wire mics for you for the Sony units. I guess my point is, if you're going to own the units, you should replace the stock mics as quickly as possible, and then wouldn't need a rental house to provide mics.

I just got the price list from OST and they are crazy affordable. At the cost of renting mics, you could purchase OST mics for your units after just a couple times of renting.

My $0.02.

Thought I'd bump this thread to ask if anyone has since made a small adapter for Sony to Sennheiser? (or the reverse)

As would be very handy indeed for those of us who have a mix of Sennheiser/Sony wireless. (or in my case where I have nearly all Sony, but if I need extras then a few more Sennheiser G3 is easy enough to borrow/beg/steal/rent, while Sony UWP-D11 is kinda nearly non-existent if I needed a few more of them specifically)

I'm posting this here for what it's worth. I was looking for the same thing recently because I want to buy used mics, which are all Sennheiser connectors. I've seen zero Sony wired ones used. Anyway, I found a link to a seller on Ebay that makes adapters. They are based in the UK, so the price is a bit excessive if you're in the states. I thought about making an adapter myself, but the threaded female jack is hard to find in the US for some reason.

Anyway, I have no affiliation with these guys, but I only found them after an excessive amount of googling, and since this is the first post that popped up in my initial search, thought I might be able to save someone a headache. I didn't buy the adapter myself (gonna just try and rewire the mic itself). If the listing disappears, the seller is micronic007

And here's a video that might help, though it's using a TA5F

Sennheiser wired lavs to work with Sony wireless? Easiest thing to do is open the connector and unsolder the wire going to the tip and solder to the ring and you're done. From the solder side here's the diagram:

 

*Tip-short tab       *Ring-long tab 

 

                     *Ground tab w/ cable clamps

Before I start soldering away, I wanted to make sure I’m clear on the method here. Attached is a photo of a cos-11d wired for  Sennheiser:

 

black wire -> tip tab

White wire -> ring tab

silver shield -> soldered to the sleeve and ring tab

 

 

So to change this to Sony (according to the cos-11 wiring diagram), white and black wires are switched but also the shield should be disconnected from the ring tab as well, right? Or is that not really important?

 

for Sony:

Black -> ring

White -> tip

Shield -> Sleeve

No that's not correct. The shield/ground and the white wire get tied together at the ground connection and the black wire goes to the tip for Sennheiser or the ring for Sony. The ring on the Sennheiser is for a line level input.

Sorry to revive an old thread.

I'm trying to make 2 adapters. 

 

The mics I have are both Headset Mics:

 

Sennheiser ME 3-EW Headset Mic (older version of the ME 3-II) for G3.

 

Sony ECM-322BMP Headworn Mic for UWP-D.

 

I feel like I'm on the right track but just want to confirm before I do some more soldering (made some boo boos)... Is this correct?

For anyone who is wondering, the above diagrams are incorrect if wanting to make ADAPTERS. 

After tons of trial and error and some amazing help by @Eric Toline and @Dalton Patterson, I ended up successfully making 1 adapter that will work both ways (G3 mic to UWP TX and UWP mic to G3 TX). 

If you want to make an adapter, you just need to wire Tip to Ring and Ring to Tip. Leave the Sleeve on both ends floating.

Since the Sleeve is the part of both connectors that provide the most stability when soldered, be sure to use a good amount of heat shrink. 

 

Here's my adapter:

I'll probably make another that's a bit longer and use a bongo tie to reduce stress on it since it is a bit top heavy.

Lots are! Depends on what termination you buy it with. Often most models give you a choice of what to pick (for instance for: Lectro/Sennheiser/Sony/Zaxcom/etc)

Congratulations on a job well done. I'm going to copy your diagram for my wiring cheat sheet.

Thanks for your help Eric!

Regarding the diagrams, they are both INCORRECT if wanting to make an ADAPTER.

 

Here is the correct wiring for an adapter:

G3 to UWP Adapter.png

 

It will work both ways but since the Shield is carrying the load of 2 wires (shield and ring wire of the G3), it may not be advisable to use it the opposite way.

If you want to make one to adapt a Sony mic to a Sennheiser TX, I'd suggest just doing the wiring like above but put the shield where the red wire would go and the red wire where the shield would go.

 

All that said... I may have no idea what I'm talking about.

I'm not sure if the labels on the 3.5mm TRS are for the wires or the solder points. If it's the solder points then they are reversed as the solder tab on the left marked as RING is the TIP solder point on that connector, same goes for the right side tab which is indicated as TIP but is connected to the ring on that connector. After further consideration and study I believe the Ring & Tip indicators show which wire goes where.

Yeah sorry, I shouldn't have colour coded the connectors. Just confuses things.

Also, on my 3.5mm Female, the long tab has a "T" on it and a multimeter test confirms it's for the tip. It may just be how Switchcraft does it.

Just found the datasheet actually:

Also, on the Male adapter I'm using, the Tip is the one that the Tip arrow is pointing to. Us Canadians have it all reversed!

 

That said, to simplify...

Female Tip to Male Ring with either Red or White wire (diagram shows Red).

Female Ring to Male Tip with Shield.

Female Shield and Male Shield disconnected (diagram shows White wires floating on both ends).
