Alto Professional Stealth Wireless

I was looking for a wireless system to replace the cables connecting active speakers. it is I finally found a product from ALTO (brand I did not know professionally). I could test it live in a packed room of 250 people in the worst conditions (material placed at 1m only with top screen as the assembly of the people in the room. Well the system has worked perfectly without ever having debonding! delivery lasted more than 7:30 seamlessly with transmitter / receiver distance of 25m . I can not yet give an opinion because the decline in use is too faible.Le system is mains powered and not battery, a + for me.
Only downside, the plan UHF frequency used is not mentioned in the instructions of the manufacturer. I have changed some of my channels wireless microphones.

I just try to benefit or several rooms was to have sound. Wall thick very low ceiling has nothing to report. The perfect signal not stall.
Most can manage the volume of each L / R channel on the transmitter.
Work in mono or stereo.
Mains. Very good product at this time.

Received today, I first a questioning look, the product seems very light and fragile.
I plugged into a linear HK, and all the terrible marches impeccable.
I shifted my satellites to 10 m and sound like and even power the same quality.
Frankly great product had to be invented for the sound I know the system from AKG wireless accordion my companion.
Now buying a bag to put the partite system.

I regret not win and what time to not store the cables.

I took the other two receivers.
