Exclamation It actually sounded clear all the time at all volume stages.

Now i see that microphone on camera has eaten most of high sounds and that was happening when the amplifier was at loud,when i lowered volume the microphone was able to pick up sound pretty well. Nothing strange,all that sound in a 40 square meters... First time when i get a chance to use it on an open field i will record a new video and than it will be possible to see that the amp does not wreck high sounds. It sounded clear all the time at all volume stages.
