Achieve great-sounding vocals with Sennheiser's ew 100-945 G4. This wireless system's SKM 100 G4-S handheld transmitter features a tight supercardioid pattern, so it picks up the vocalist while eliminating feedback. The ew 100-945 G4 also includes an EM 100 G4 rackmount receiver, which offers 1,680 tunable UHF frequencies across a 42MHz bandwidth for interference-free reception. This system is highly expandable — you can link up to twelve receivers for simultaneous setup. And you'll benefit from a 330-foot transmission range and up to eight hours of operation. Beyond that, the ew 100-945 G4 is backward-compatible with previous evolution systems, ensuring that your past investment continues to pay off into the future.
