Sennheiser AC 41-US Reviews

EXCELLENT!

After researching a few different options for a combiner to help with some static / interference we were getting with our Sennheiser In-Ear Monitors - I decided to go with this unit. Since installing in our rack; we have had absolutely no static, no interference - it solved all of our issues! The ability for this unit to also power our units using the power over BNC connection is also a very nice surprise; taking up fewer valuable outlets in my power distribution. I'm quite pleased with this unit and very happy that I bought it.
