would like to share my experience with Xvive U3 wireless mic system i’ve been using for last few weeks now. I have connected 2 x U3 (for short) transmitters to the XLR L/R outputs of Bose T8S mixer (although one site need a very short extension due the physical dimensions of the units: without the extension, they simply won’t fit into the very tight space of the T8S inputs/outputs sit). The receivers are connected to the channel 1 on each of my Bose S1 PRO.
System works flawlessly for us although distance between the T8S and either S1 PRO is usually no greater than 5-6 meters- that’s what we want: to hear ourselves via S1 PRO. But we have also tested that entire system for greater distance of approximately 12 meters on each site to see if there is any of dropout or degradation of sound. It does work very well, no problem. Batteries (recharcheable) would last approximately for up to 5 hours (U3) and S1 PRO batteries will work in similar fashion too. So they are totally wireless.
We havexexperience kind of statering noise and dropout once when microwave oven has been used innext room (not on the gig, just at home during the rehearsal. But that happened only once..
Great idea, great product, good quality, very quick paring system and overall we are happy to use it instead of the traditional cables (but we do carry these ones in the car, just in case).
Also U3 do have that mic/line switch which in our way of using it is important, ‘cos mic position might and often run too hot on some occasions. Line position however is just perfect, no distortion or obvious degradation of sound quality.
