OVERALL OPINION

I needed two microphones quite versatile, allowing me to catch close enough variety (wood, strings, brass, percussion) and taken together as a couple of stereo. All these features are present on the B2. For now, I have used in the first configuration, with no complaints to report, if not a preamp before the table is not the luxury (but this is due to the console, not speaking) .
The value for money is excellent, no regrets.
