Sennheiser Wireless Microphone System

Professional UHF wireless lavalier system for camera work

Sennheiser Wireless Microphone System is a compact professional UHF lavalier setup based on the proven evolution wireless ew 100 platform. Depending on availability, the rental unit may use the G4 or G3 generation, with a matching bodypack transmitter and portable camera receiver. Both generations are widely used for interviews, documentaries, corporate shoots, events and run-and-gun filmmaking because they combine stable analogue UHF transmission with straightforward frequency management and robust metal housings. The lavalier microphone can be hidden on the speaker while the bodypack transmitter remains clipped to clothing, giving the camera operator a clean wireless signal without a cable running between talent and camera.

Adaptive-diversity reception and flexible UHF tuning

The portable receiver uses adaptive-diversity reception to improve RF stability during handheld and camera-mounted work. The ew 100 platform offers up to 42 MHz of switching bandwidth and as many as 1680 tunable frequencies in 25 kHz steps, depending on the frequency band of the specific unit. Twenty preset frequency banks provide up to 12 coordinated channels per bank, while an additional user bank allows manual frequency programming. Automatic frequency scanning helps identify clear channels, and infrared synchronisation allows compatible transmitter settings to be transferred quickly from the receiver.

Camera and recorder connectivity with mini-jack and XLR

The receiver provides a locking 3.5 mm audio output and can be mounted directly on a camera accessory shoe using the supplied adapter. The CamCam configuration includes both a mini-jack to mini-jack cable and a mini-jack to XLR cable, so the system can be connected to a typical DSLR or mirrorless microphone input as well as to professional recorders, mixers or cameras with XLR audio inputs. Output level can be adjusted on the receiver to match the connected device, helping avoid excessive noise or input clipping.

HDX companding, pilot-tone squelch and long AA battery operation

Sennheiser’s HDX compander is used to maintain a high signal-to-noise ratio across the analogue wireless link, while pilot-tone squelch helps mute unwanted RF noise when the paired transmitter is switched off or lost. Both the SK 100 bodypack transmitter and EK 100 receiver run from two AA batteries or a compatible BA 2015 rechargeable pack. Typical operating time is around eight hours for G4 hardware, with G3 units offering a similar full-shooting-day runtime depending on battery condition. This makes the system practical when batteries need to be replaced quickly on location without waiting for internal charging.
