need Help with Lav wiring

joaquin · 7th May 2010

Hello.
I just got the Lectrosonics SMQV transmitter and want to wire a Sennheiser ME2 Mic to the TA5F connector.
here is a Link to the schematics

I believe is Fig 2.

How do I split the signal from the Audio cable to the 3 pins in the connector?
Thanks for your Help!

The Sennheiser mic is unbalanced... hot and ground. I know my mini-TRS connectors (built by Trew for Sennheiser transmitter packs) have the hot lead soldered to a resistor that bridges pins 2 and 3, with the shield to pin 1.

Call the guys at Trew Audio's repair shop (Trew Audio: Location Sound Equipment Sales, Rentals & Service for Film & Video Production throughout the US, Canada, and the rest of the world.) and ask again... especially concerning the resistor value for the Sennheiser mic. Or... just start with shield to ground, and hot to pin 3... Figure 9, I believe.

Be very careful with the iron... mini connectors get messy really quickly with too much heat.

Thanks BH.
I'm waiting for the Lectrosonics Tech to give me some directions...
I'll post once I get the Mic working.
Thanks!

It was figure 2.
The ME2 is a 2 wire positive bias mic.
After the clarifying Tips from the Lectrosonics Tech, the soldering was pretty straight forward. The Audio goes to one pin (3) and there is a jumper from pin 2 to four.
The ME2 sounds fantastic for the price of the mic, and now with Lectro's Technology...even better
