Product Overview

The Sennheiser EK 100 G4-A1 is the standalone portable camera receiver for the EW 100 G4 wireless system, operating in the A1 band (470–516 MHz). Identical in design and features to the EK 100 G4-A, it provides true diversity reception with 1680 selectable frequencies in the A1 frequency band for ENG, broadcast, documentary, and corporate video production workflows. At $349.95, it is the camera-side component for professional wireless audio in the 470–516 MHz spectrum.

Product Description

The EK 100 G4-A1 is functionally identical to the EK 100 G4-A with the sole distinction of operating in the A1 frequency band (470–516 MHz) rather than the A band (516–558 MHz). Select this variant when your EW 100 G4 transmitters operate in the A1 band, or when local frequency regulations or RF conditions make the A1 band the preferred choice for your region. The true diversity receiver uses two independent RF paths for reliable signal on moving cameras. The 1680 selectable frequencies across the A1 band provide professional frequency coordination capability for dense multi-system broadcast environments. The compact camera-mount form factor connects to standard camera hot shoes, cold shoes, and cage mounting systems. Output is via 3.5 mm TRS with adjustable level for camera audio input compatibility. The graphical display shows RF level, AF level, and transmitter battery status. Infrared sync allows fast field frequency pairing. The EK 100 G4-A1 is compatible with all EW 100 G4-series transmitters operating in the A1 band, making it the portable receiver choice for any EW 100 G4 A1-band wireless microphone system used in broadcast and video production.

Frequently Asked Questions

How do I choose between the EK 100 G4-A, -A1, and -G?

Select the band that matches your transmitters. The A band (516–558 MHz), A1 band (470–516 MHz), and G band (566–608 MHz) are not cross-compatible — transmitters and receivers must be in the same frequency band. Choose based on which band is available and license-compliant in your region, and which band your existing EW 100 G4 transmitters operate in.

What transmitters are compatible with the EK 100 G4-A1?

The EK 100 G4-A1 receives from all EW 100 G4-series SK 100 G4 bodypack transmitters and SKM 100 G4 handheld transmitters operating in the A1 band (470–516 MHz). Transmitters in other bands (A, G) are not compatible.

Is the output level adjustable?

Yes. Output level is adjustable on the receiver to match the input sensitivity of different camera models and portable recorders.

What cable outputs are included?

The EK 100 G4-A1 includes a 3.5 mm output cable and an XLR unbalanced output cable, along with a camera mount.
