Sennheiser Wireless Dynamic Microphone System Supercardioid

The Sennheiser 509742 is a wireless dynamic microphone system developed for performers who demand dependable sound on every stage. It brings together Sennheiser’s proven RF technology and the respected MMD 945-1 supercardioid capsule, giving singers, presenters, and musicians a clear, feedback-resistant vocal sound.

The handheld transmitter houses the capsule in an aluminum body that is light to hold yet built to handle nightly setups and travel. A conveniently placed mute switch offers silent control when you need to step away or cue the next segment.

With up to 42 MHz of selectable bandwidth in the UHF range, the system provides as many as 20 compatible channels and supports up to 12 linked systems operating at the same venue without interference. A dependable 100 meter transmission range lets performers move across large stages, conference halls, or houses of worship without losing connection.

Setup is quick and intuitive. An infrared link synchronizes the transmitter and the true diversity half-rack receiver in seconds. The receiver’s LCD screen presents frequency, RF strength, audio level, and battery status at a glance, so engineers can keep an eye on every critical detail during the show.

From club tours and corporate keynotes to worship services and school productions, the Sennheiser 509742 delivers the clarity, flexibility, and road-ready build quality that working professionals rely on night after night.
