Connecting Tram Tr50 lav with TA5F connector to a Sennheiser G3 bodypack transmitter?

Well-known member
Has anyone does this and if so, what do I need to buy, watch out for, etc.

Example:
- do I need to worry what bias the tram is?
- if the bias need to be the same but are different, can I do some form of modification somewhere like on the adaptor, or DIY cable to make them work together?
- what adapter or cable do I need to make this work and do you have links to the product?

Thanks
 
I've done a few. Is the Tram in question a two or three wire version? Positive or negative bias?
As Alex stated, You need to send the mic in and have it re-terminated for Sennheiser G3.
It's not a job for the inexperienced in any case. Any of the location audio shops could do it. (Trew, Gotham, LS, TAI, ect.)
 
If you don't want to permanently change the lav then I have seen adapters that will make the change. but then you have a fairly awkward belt pack.
 
I have conflicting information online that states:
- sennheiser g3 100 requires positive bias mics
- sennheiser g3 can accept both positive or negative bias.

Can someone please confirm which statement is true? Do you have a negative bias mic connected to the G3 and it works flawlessly with no quality degradation?

Does it also matter whether you have the older version tram with 2 wires or newer version with 3 wires for it to work?

I have a negative bias tram and sending it over to the manufacturer to change termination is out of the question due to costs. I am an experienced solderer, just the electronic theory side I am not good at. I am paint by numbers when it comes to electronics :)
 
Does anyone know if changing the bias from negative to positive on a tram tr50 is a simple matter of changing the wiring on the plug?

thank you
 
I don't believe you can change the bias of a mic. There may be a way to add some components in the plug to do so but?
 
My TR-50s were positive bias. The older Tram; two-wire, the newer.. three. Never had a negative bias to try.
I don't believe is possible to invert the bias either... at least from logical-economical standpoint.
