The Sennheiser EW100 G4-945 is a versatile true diversity handheld wireless microphone system. It has a huge plethora of uses. Singers, presenters, orators, and musicians alike will find something to love about the powerful, crystal clear sound reproduction of this system. For state-of-the-art sound featuring Sennheiser’s renowned quality, this system is perfect for professionals. It has a tuning bandwidth of up to 42MHz in a stable UHF range and allows for fast, simultaneous setup of up to 12 linked systems.
State-of-the-art live sound featuring a choice of Sennheiser‘s renowned 835, 845, 865, 935, and 945 capsules on a lightweight aluminum transmitter with integrated mute switch.

While the 800 series capsules have an EQ designed to help your vocal cut through the mix, the 900 series capsules offer a more natural sound ideal for large scale PA systems or performance spaces. The 935 features a cardioid polar pattern that rejects sound from the sides and rear and is ideal for most stages. For louder stages that are susceptible to feedback, the super-cardioid polar pattern of the 945 will come into play, as it provides even more isolation for your vocal performance.
