Following on from my previous post –

I just did a job today using the G3s to link my SD302 to a Sony EX3 camera.
The RXs were set to -12db giving good level to the cam mic input (knob set to 5)
– Line input would be ideal but I couldn’t get enough level from the RX to drive the cam line input without having to turn it’s gain to near max (10).
My noise problem (stray RF?) wasn’t apparent (although I wasn’t able to check in an ideal monitoring situation.
When checking the system the day before I did notice that the noise did drop quite a lot after I put fresh batteries in the SD302 – the old batts were low but still functioning without the LED warning flash.
Could an RF choke on these unbalanced leads help? Does anyone have any ideas re the effect of mixer battery voltage on the noise source.
Any more diagnostic strategies?

Hi All – New poster to CC

I’ve been dealing with this set up with mixed results – Linking my SD 302 mixer to various cameras via a pair of Sennheiser ew 100 G3’s. I’m going SD302 Tape Out (3 pin TA3) >G3 TX line in (wired with signal to ring of jack plug).
The RX level to cam seems low for line level inputs of ‘big’ (Digi Beta) cameras but level is ok for mic input. Levels are good for small cams.

My main problem is low, intermittent noise (only through the G3 hop/link) when touching the mixer/wireless bag especially when metal to metal ie ring of harness touching mixer case. It reminds me of radio static.

I made the current lead according to the info near the end of the thread at PSW -(see link below) ie: signal to ring, tip and sleeve both to ground.

I’m wondering if the mic power voltage (5v) on the tip could affect the line signal
when it is grounded.

– maybe needs a resistor or capacitor??

I’ve made my own leads for years but would appreciate some feedback….back to the soldering iron.
