Achieve great-sounding vocals with Sennheiser's ew 145 G4. This wireless system's SKM 100 G4-S handheld transmitter features a tight supercardioid pattern, so it picks up the vocalist in front of it while eliminating feedback. The ew 145 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 145 G4 is backward-compatible with previous evolution systems, ensuring that your past investment continues to pay off into the future.
