Sennheiser G4-865-S Wireless Microphone System

The Sennheiser 509785 is a complete wireless microphone system that gives presenters, educators, and business professionals the freedom to move while keeping speech clear and consistent. It pairs the SKM 300 G4 S handheld transmitter with the MME 865 1 microphone capsule, creating a solution that feels comfortable to hold for long sessions and captures voice with supercardioid condenser precision, even in rooms with crowd noise or reflective surfaces.

At the heart of the system sits the EM 300 500 rackmount receiver. It offers a wide 88 MHz tuning range and supports up to 32 channels, so multiple microphones can operate in the same venue without signal conflict. An integrated network port lets staff oversee frequency scans, battery status, and audio levels through Sennheiser Control Cockpit or WSM software, making system checks quick before a lecture, service, or corporate meeting.

Speakers can rely on a transmission reach of up to 100 meters, enough for conference halls, large classrooms, and worship spaces. The handheld transmitter runs for roughly eight hours on two standard AA batteries, which means full-day workshops can finish before a change is needed. A noiseless mute switch sits on the body for discreet control when side conversations arise.

Setup remains flexible. Rackmount the receiver near a mixing console, link it to a network for remote monitoring, and, if desired, pair the system with the Sennheiser LSP 500 PRO wireless speaker rig to create a portable, cable-free sound solution. Whether leading a training seminar, moderating a panel discussion, or addressing a congregation, users can expect dependable audio, straightforward operation, and hardware built to withstand daily handling.
