Not sure if this feature is supported, but can I use lav and a butpluged mike at the same time with the same receiver, so far I'm getting just a lav signal plus some squeaking noise from the butplug (SKP 100);
thanks!
It would be cheaper at this point to just buy an additional Sennheiser EK100 G2 receiver if you want to use both. Around $365. Maybe check eBay for a used one if you can find your frequency.
Jumping over to the Audio Technica, Lectrosonics or Zaxcom is going to be over $1500 for a dual channel set-up.
Depending on what camera you are using, you might also want to consider a "Mic Mate"
