STCM_Tech Posted April 18, 2013 Share Posted April 18, 2013 We have five Sennheiser Evolution G3 Lapel sets. I was looking for something like SKP 300's that Sennheisers do. But then I saw the price. Would the Sennheiser CL2 let me connect a standard hand held mic to one of the Sennheiser body packs we already have? Link to comment Share on other sites More sharing options...
dwright2104 Posted April 18, 2013 Share Posted April 18, 2013 Yes, but if you use a +48v mic battery life is sometimes hard to predict. have used the cable in the past to transmit a small mixer to the in house system, which was all locked up with no way to access inputs except the two mics.

STCM_Tech Posted April 18, 2013 Author Share Posted April 18, 2013 I just want to use it with a few SM 58's so we are cool! Cheers Link to comment Share on other sites More sharing options...
Shez Posted April 18, 2013 Share Posted April 18, 2013 Yes, but if you use a +48v mic battery life is sometimes hard to predict.It would presumably also be quite hard to hear as you can't get 48v out of those beltpacks...There's only a bias voltage of ~5v for powering electret capsules.

pete10uk Posted April 18, 2013 Share Posted April 18, 2013 100% yes I have just tried a SM58 and it worked a treat. Had to set the sensitivity to -3 or -6 to get anything real out. @ -0 the belt pack was just running on full peak constantly. Phantom power wise, I have also tested it on a shotgun mic which stipulates 48v phantom and it worked. Link to comment Share on other sites More sharing options...
Shez Posted April 18, 2013 Share Posted April 18, 2013 Are you sure that shotgun didn't have a battery in it? Whilst some mics that can be powered by P48 will work on as low as 12v, true condensors that need the full 48 have no chance with such a low voltage. I've just measured the bias voltage from a senny beltpack - 8.8v. The SKP mentioned earlier can of course provide the full 48v as that's what it's designed to be able to do (with the resultant battery hit of course).

The unit is AT875R No place for batteries however the online spec states 11-52v despite the mic having 48V printed on it. Link to comment Share on other sites More sharing options...
paulears Posted April 18, 2013 Share Posted April 18, 2013 and the phantom power is carried on the two conductors, and the Sennheisers are unbalanced - so there is only 1. The only way it can be working is that the 5V superimposed on the audio line is sufficient, via the internal resistors in the mic designed to recover the phantom, to power the preamp. Before you use it in ernest, check the performance with loud sounds. I have a AT 815 that works on lower phantom power at about 12V - BUT overloud sounds distort quite unpleasantly. It's luck it's working, NOT design. Link to comment Share on other sites More sharing options...
Shez Posted April 18, 2013 Share Posted April 18, 2013 Interesting. There's a review on AT's site for that mic that suggests it'll even work on the 2.4v plug-in power that some camcorders and DSLRs provide. I believe headroom and sensitivity are what can suffer with lower voltages though.A useful one to keep in the toolbox then! Link to comment Share on other sites More sharing options...
STCM_Tech Posted April 18, 2013 Author Share Posted April 18, 2013 Sounds like everyday is a school day for all of use then! Pete thanks for checking it with a 58 for me!Will save me running a massive muticore for two or three mics if I can get a few of those. Link to comment Share on other sites More sharing options...
