Sennheiser is a perfect choice for outstanding performance if your church is using a large amount of G3 wireless systems
on multiple campuses. The high quality of Sennheiser's microphone capsules, particularly the e 965 are a compelling reason to choose Sennheiser mics over competitors. Even if you run upwards of 105 dB frequently, this capsule handles it extremely well, with more control over sibilance. All of that and you'll get the fine audio detail and tonal definition that you want in your mix.
Sennheisers networkability and integrated antenna distribution, which is included in the 2000 series receivers
can be very helpful for monitoring and control, and is not a feature you can find on other microphones from competitors in the same price range.
