Season's Greetings!

I'm considering getting an AT873r to run with an ew 100-ENG G2 package. My question is whether a non-battery powered mic like the AT873r can be powered by the SKP 100 plug-on transmitter. I thought it would work, but I read specs somewhere that listed "Phantom Power = no" for the SKP 100. So now I'm confused (nothing new for me). :)

Thank you for any insights!

The AT873r requires full 48-volt phantom. You'd have to use either an external battery-powered phantom supply between the mic and the transmitter (kind of clumsy and defeats the purpose of a plug-on transmitter) or go up to the 500 series plug-on transmitter. It supplies 48v phantom, but I'm not sure if it can properly transmit to the 100 series receivers or only to the 500 series receivers.

Hi Jay:

Thank you for the clarification. Just FYI, it looks like they sell 100/500 series packages (like this one at BH http://www.bhphotovideo.com/bnh/controller/home?O=NavBar&A=getItemDetail&Q=&sku=349266&is=REG&si=feat#goto_itemInfo), so the 500 must transmit to the 100.

But for the amount of money they want for a 500 plug-on, I wonder if it'd be smarter to put money into a different mic instead? What do you think?

Is there such thing as a good battery powered hypercardiod mic for under $300 that you can recommend?

Thanks again!

Ben

Unfortunately, the only really good-sounding battery-operated hyper that I know of is the Rode NT3. It's rather large and heavy for any use outside the studio.
I guess I should ask, how exactly are you planning to use this mic. If it's on a boom pole, then my earlier comment about using an external phantom supply being clumsy isn't really accurate. It's actually better to keep the plug-on transmitter on your belt with a cable running to the mic. It's not a big deal to add a phantom supply on your belt too. This minimizes the weight on the end of the boom, and reduces dropouts caused by constantly swinging the transmitter around on a conductive pole that acts like a second transmitting antenna (which is bad).

Hi Jay:

Yes, I was thinking about wireless boom operation. Your proposed setup sounds (padon the pun!) convenient.

On a related note, do carbon fiber boom poles cause interference/drop outs or is that limited just to aluminum.

Thanks again for sharing your experience.

Carbon conducts electricity too, so the same applies with their potential to create dropouts, as well as interference in cheap cables wrapped around them when going wired, as well as electrocution risk. Maybe someone can come up with a cheap, light, non-conductive material for future use. Too bad fiberglass is so heavy.

Maybe there's something to that bamboo boom pole suggestion!
