Put an end to cable clutter

I use the Alto Stealth radios to send my vocal microphone from the drum set to the mixer and from the mixer to my in-ears (I operate two different radio channels with a total of two sets of Alto Stealth 1 XLR radio transmission systems.
The devices easily run for 5 hours on AA batteries (yes from Rewe or Duracell). However, I operate the devices on the mixing console using the USB cable supplied via a power bank. This makes a premature crash virtually impossible.
The transmission is latency- and noise-free and meets my expectations of a proper stage sound.

It's a shame that Alto Stealth doesn't also offer devices that I can use with my ambient omnidirectional microphone (requires 48V phantom power). I'll probably have to resort to the much more expensive branded devices that are available for this purpose.
Very good!!!

I used this system for the first time last weekend. Using a mixing console (Mackie) and a low-cost microphone (t.bone MB 55). I never expected this quality in my life. Highly recommended.
