Donner EM1 Portable IEM Amp Review

[Kaakatus]

For those who wonder, XLR has the same amount of connections (3) as the stereo jack but it locks in place. So, you can have stereo from a combo jack with both connectors.
Based on the results the product looks fine. What I would be interested is how it behaves next to radio antennas (how much radio signals get in through the plastic body) ja how well the volume knob works. Stiffer the better so your clothes wont chance the volume. Also, build in limiter is a very important feature for protect your ears for any unintended pops or feedback.
Behind drums, I use Fisher amp and Shure SE425. Going to wireless would not bring any value. Now I only need to take care of fresh batteries.

I have had no issues with mine picking up unwanted RF noise. Volume control is good - it's easy to adjust intentionally, but stiff enough that you won't accidentally crank the volume by knocking it. I typically get the sound guy to give me a test tone that's as loud a signal as I'm going to get from the board and then adjust my max volume accordingly.

I'm not really sure what purpose this has, considering the output is so poor and the performance is also just "ok"
