Not very cool ..... the d3500
I bought it for the anti feedback but it does lead before three perform all necessary, in addition I had a cot in a rack Receivers Sennheiser 300 Series is regardless of the frquence I was a parasite on the path of the receiver 2,
since I use it as a filter, I think even sell it as possible.

UTILIZATION

Caution manual in English

SOUND QUALITY

For me the only filter manual is ok

OVERALL OPINION

Its been a year since I use is I give up.
