Product Overview

The Sennheiser EK 100 G4-A is the standalone portable camera receiver for the EW 100 G4 wireless system, designed for ENG, broadcast, and video production applications where a compact receiver mounts to the camera or connects to a portable audio recorder. Operating in the A band (516–558 MHz) with true diversity reception and 1680 selectable frequencies, it receives audio from any compatible EW 100 G4 SK bodypack or handheld transmitter. At $349.95, it is the camera-side component for professional wireless audio on mobile and studio production setups.

Product Description

The EK 100 G4-A is a portable true diversity camera receiver optimized for field production, broadcast, and professional video workflows. The compact form factor clips to camera hot shoes, cold shoes, or standard mounting systems, placing the receiver on the camera body for convenient monitoring and control during recording. The true diversity receiver operates on two independent RF paths simultaneously, continuously selecting the stronger signal to eliminate dropouts — essential for moving camera operators who cannot control their distance or orientation to the transmitter. With 1680 selectable frequencies across the A band (516–558 MHz), the system provides the frequency agility required for busy broadcast environments and multi-system field production deployments. The receiver outputs audio via 3.5 mm TRS for connection to standard camera audio inputs, with output level adjustable to match camera sensitivity requirements. The graphical display shows RF level, AF level, and transmitter battery status. An infrared sync port allows fast transmitter/receiver channel pairing. The EK 100 G4-A is compatible with all EW 100 G4-series SK bodypack transmitters and SKM handheld transmitters in the same frequency band, making it the camera-side component for any EW 100 G4-based wireless microphone system. It is the correct choice for camera operators, documentary filmmakers, corporate video crews, and broadcast professionals who need professional-grade portable wireless reception with camera-compatible output.

Frequently Asked Questions

What transmitters are compatible with the EK 100 G4-A?

The EK 100 G4-A receives from all EW 100 G4-series SK 100 G4 bodypack transmitters and SKM 100 G4 handheld transmitters operating in the A band (516–558 MHz). Transmitters in other frequency bands (A1, G) are not compatible — band must match.

How does the receiver mount to a camera?

The EK 100 G4-A has a mounting foot compatible with standard camera hot shoes, cold shoes, and camera cage mounting systems. Check the specific mounting hardware compatibility for your camera platform.

Is the output level adjustable for different camera sensitivity requirements?

Yes. The EK 100 G4-A provides adjustable output level to match the input sensitivity of different camera models and portable recorders.

What is the difference between the EK 100 G4-A, -A1, and -G?

The three variants operate in different frequency bands: A (516–558 MHz), A1 (470–516 MHz), and G (566–608 MHz). All three are identical in features and function. Select the band appropriate for the transmitters in your system and the frequency regulations in your region of use.

Can the EK 100 G4-A be used as a stationary receiver in addition to a camera receiver?

The EK 100 G4-A can be placed on a desk or in a fixed position via appropriate mounting accessories, but it is designed as a portable battery-powered camera receiver rather than a rack or tabletop fixed receiver. For permanent installations, the EM 100 G4 is the appropriate receiver.
