soundslikejustin Posted December 4, 2012 Report Share Posted December 4, 2012 Make it yourself, or get your dealer to make it for you - it's going to be a custom cable either way. If you make it yourself, connect the left and right ouputs of the TA3 (not sure of the pin assignments but probably 2 and 3) to the ring on the 3.5mm, and the ground to both the tip and ring.

Alistair Duff Posted December 4, 2012 Report Share Posted December 4, 2012 I think I will need to build it myself.. which Ill enjoy doing, However I need to put resistors inline to prevent shorting but am not sure of the correct value. Anyone? Quote Link to comment Share on other sites More sharing options...
stefanosound Posted December 4, 2012 Report Share Posted December 4, 2012 the input of senny is -10 db unbulanced on the ring, Tip is mic unbanced input. <So you have to put two resistor onthe pin 2 an 3 on the ta3 pin 2 resistor reistor pin 3 betweeen the two rewsistor you have the mono to connect at the ring shold be 10khom sorry for my bloody english...

Rick Reineke Posted December 4, 2012 Report Share Posted December 4, 2012 "the input of senny is -10 db unbulanced on the ring, Tip is mic unbanced input." - Yes, the input of Sennheiser G2/3 SK-100 body pack transmitter will accept a -10dB nominal signal unbalanced to the ring connector,.. when configured for line level, the tip must be tied to the sleeve/ground Quote Link to comment Share on other sites More sharing options...
Matt Geldof Posted December 7, 2012 Report Share Posted December 7, 2012 Has anyone thought to build a cable with in line variable attenuation or switching of ring to sleeve, in the case of the sennheiser units, and panning? I can think of a dozen occasions, where the panning option would have been convenient. I opted to instead build a TA3 to 3.5mm stereo splitter cable and swap out when needed. I couldn't find a small enough 3 way switch, at the time. Quote Link to comment Share on other sites More sharing options...
Vincent R. Posted December 7, 2012 Report Share Posted December 7, 2012 That has to be some protected switch then, you don't want accidentally bump and switch it during a take... Quote Link to comment Share on other sites More sharing options...
pkautzsch Posted February 11, 2015 Report Share Posted February 11, 2015 Resurrecting this wiring thread as I'm currently trying to cheap out on a second private comms feed that's bag based. Using a G3 transmitter with IEM RX for my boom op anyway, feeding the 788T's slate mic to both the main comteks and his G3. Now I want to add another mic that feeds only the boom op's G3. A cheap solution - if it works - would be connecting his feed to the ring and a mic to the tip of the G3 input. Anybody tried this? Is it worth a few minutes of soldering? I have read these threads that also have significant info about G3 wiring but not about double use: Another cheap solution is: send mic level out of the 788T output, and passively sum them. I would like to not add another box that needs powering. Quote Link to comment Share on other sites More sharing options...
jlempen Posted February 12, 2015 Report Share Posted February 12, 2015 Hi all! This tech note from Sound Devices might be interesting if you want to add a summed mono output to your 302 tape out while keeping the L and R outs: http://www.sounddevices.com/notes/mixers/302/302-tech-note-adding-a-mono-mic-level-output/ The document includes schematics and resistor values for both mic and tape levels.

JensF Posted May 24, 2016 Report Share Posted May 24, 2016 The link seems to be dead. I'm making a standard TRS jack to summed G3 line level input. Have any of you had any luck with this wiring without any in line pading? Standard stereo source: Tip - hot Ring - cold Sleeve - ground G3 line input: Tip - ground Ring - hot+cold Sleeve - ground Quote Link to comment Share on other sites More sharing options...
Derek H Posted May 25, 2016 Report Share Posted May 25, 2016 You could try it and it might work but there are electrical reasons that you should use resistors in the cable to sum the two signals. Look at this: http://www.sounddevices.com/tech-notes/adding-a-mono-mic-or-tape-level-output-to-the-302 Quote Link to comment Share on other sites More sharing options...
RPSharman Posted May 25, 2016 Report Share Posted May 25, 2016 Wait... what? You want to feed a 'L' signal to go out to boom op, and a 'R' signal to go to client? I don't think you can have a G3 transmitter (belt pack) fed a stereo signal and have it transmit left to an IEM for director and right to boom op IEM. I don't think they work that way. The base station has a proper L/R input and can send a stereo signal, and it is possible then to have one set of IEMs receive the L and another set receive the R. Lots of people here in the UK have that setup. But I don't believe the belt pack has that option. It isn't "stereo", it's balanced mono. I'd love to be corrected if I am wrong.

Rick Reineke Posted May 27, 2016 Report Share Posted May 27, 2016 You are absolutely correct RP. The SK series transmitters are mono, however they can feed the IEMs receiver a mono signal and the HDX compander (noise reduction) is compatible. In order to do what the OP desires, a complete SW300 system would be needed, which has separate L&R inputs on the x-mitter and the receivers allow the user to select, stereo or a mix or the two, for instance a vocal / instrument mix. If feeding an G2/3 SK100 series bodypack transmitter, 3.5mm plug's the ring terminal is line level, though it will likely distort with full +4dB program material, so a 10 or so dB L-pad is recommended. The SR300 IEM transmitter handles inputs to 22dBu. Quote Link to comment Share on other sites More sharing options...
