Sennheiser e945 Capsule Wireless Microphone System

The Sennheiser 509741 is a wireless microphone system built for singers, presenters and audio crews who need dependable sound from soundcheck to encore. At its center sits the e945 supercardioid dynamic capsule, which focuses on the voice and keeps feedback under control even on loud stages.

The handheld transmitter uses aluminum construction that feels sturdy yet light in the hand. A convenient mute switch lets performers silence the mic instantly during set changes or backstage conversations. Power lasts up to eight hours, so rehearsals, services and full-length shows run without battery anxiety.

The rackmount receiver employs true diversity antennas for a stable connection. A clear LCD shows frequency, level and battery status at a glance, and the full metal chassis stands up to the bumps of touring or daily venue use.

Frequency management is straightforward. The 42 MHz UHF bandwidth offers 1,680 selectable channels, and the built-in scan function finds open space automatically. Infrared sync pairs the transmitter in seconds, and you can operate up to twelve linked systems in the same room without interference. Once set, the link remains solid at distances up to 100 meters, giving performers freedom to roam.

From concert stages and corporate events to houses of worship and rental inventories, the Sennheiser 509741 delivers the clarity, range and build quality professionals expect when the show has to run smoothly.
