Used for two years, not a failure, not a single case of intensive use dfaillance (4 benefits per week)

trs a good product, similar to a stereo sound

lacks a little low, need a box ds s'largit sound with the volume to be 100 people

a default: a grid fragile! prvoir the carrying cases

from the DAS hardware is really good, a tone below the Chilton amplified significantly higher!

Price relative quality: excellent
choice I would do without problem!
