[QUOTE="Diogo Pereira, post: 213670, member: 10560"] So... if we're talking about "transmitter combiners" and you need 10 INPUTS, you can consider: 1) using a passive combiner to combine two active combiners (8+4 for example). Shure [URL='https://www.shure.com/en-US/products/accessories/pa821a']PA821 [/URL](8 input combiner) + [URL='https://www.shure.com/en-US/products/accessories/pa421b']PA421 [/URL](4 input combiner) combo will give you the 12 inputs you need and both have a passive combiner built-in the front of the unit. You will lose 3 dB (half-power) on each carrier, but hopefully you can compensate for that upfront with transmit power from the IEM units. What model of IEMs are you using? 2) Second option: use 2 transmit antennas. No passive power loss. Hope this helps. Cheers [/QUOTE]
