LD Systems MEI 100 G2 B5

It's a pretty good in-ear system for it's price. And do not expect a super great sound quality. It does it's job well, but it's not a hi-end gear. There's a lot of noise in the sound and it's quite sharp I guess.
Anyway it works. The system has got 10 groups of twelve channel. It's 120 channels in total. The rack mount is also included.
The reciever covered some a non-slippery rubber which is good for handling.
The bright LED display.
There are two inputs through which you can send two independent signals. Each of them has its own volume knob. And there's also a mono/stereo mode. For exampe you can send a guitar into the left input and a mix into the right. You can work in the stereo mode but if your headphone will suddenly fall off you will lose one of these signals. That's why the mono mode is the very useful feature.
I think this system will be suitable for work on a small stage, for example in a night club.
And please be careful with radio frequencies 'cause some of them is not allowed in some countries. Be sure these frequencies are legal for your country.

I recently had the pleasure of using the LD Systems MEI 100 G2 B5 in-ear monitoring system during a live performance, and it exceeded my expectations in every way. The sound quality is crystal clear, with a full frequency response that makes every note and nuance come through beautifully. The system provided a consistent and reliable audio feed without any dropouts or interference, even in a crowded venue with a lot of wireless traffic.
