LD Systems MEI 100 G2 B6

I've been using that for months now. In our band we have a wireless in ear monitoring system in use . All of us have individual stereo mixes. The in ear system is quite cardinal since for us the stage is silent. Guitars are from Headrush and 11Rack, only the drum is acoustic.
It is very easy to handle. Paring the devices is just some clicks.
The in ear phone work surprisingly well. Metal housing, comfortable, and also its sound is decent. For me it is completely enough, and I am not planning to upgrade them.
The value for the money is OK.
Cons:
- the input level knob of the transmitter is on the back of the unit. If you built that into a rack, then it is not so easy to tweak.
- there is no free frequency search function

During band practice sometimes it sounds perfectly sometimes it has some interference. I am too lazy to find myself a noiseless frequency. In case it would be one click in the menu I would definitely use that.

I had 4 concerts and countless practices with the unit and I am still satisfied with that, I think for me the next level does not worth the money because I am totally fine with that and playing live is much more fun since I do not rely on floor monitors and without playing activity with mix engineers.

Hello...

Strange things happens during running this device.
In "stereo mode" i have very much of radio noise in ears, actually i cant find a place and a frequency (within all range) without noise.

In "mono mode" situation is much better, but some little jitters have place. It is very uncomfortable because it hast any logic, even if you stand in one place noise can appear like splash, very loud and short.
I used mei-100 G2 before and the same problems was there, i return them. I thought it was frequency problems, but seems to be not

I tried to use sennheiser omni antenna (460-960 MGhz) but it has no impact on signal quality on any mode.

Next, i just turn the receiver on and hiss immediately going to in-ears. its like white noise on low volume, after i volume up, music covers up the noise, maybe this noise is operational but its very irritative.

I running 3 of shure radio systems ( microphones all of them) and no one of them produces noise on G2 frequencies (830MHZ and above).

i will look forward to other systems like psm 200 or psm300 the others are extremely expensive.

PS all this was because of noise wihtin 653-662 MHz. And also combiner must have for 2 or more devices

These are good units, i got 2 of them.
The transmitter is simple to use and feels sturdy.
Didn't have any issues the signal is strong across longer distances even thru walls.
The only thing i don't like is the rubbery antenna on the receiver, it came partly off of one, so i had to glue it in place.
The sound is ok, you can't expect it to be as it was wired, there is a hiss at all times on both units, i guess this is normal and it's not too distracting, also there is a roll off in the lower frequencies.
The headphones that came with it are kinda bad, i replaced them right away.
All in all a good entry level in ear wireless.
