Sennheiser EK 100 G4 Portable Camera Receiver (A1: 470-516 MHz)

Camera-mount wireless receiver for ENG, documentary, and field production in the A1 frequency band

The Sennheiser EK 100 G4 in the A1 band (470-516 MHz) is a portable wireless receiver designed for camera-mounted wireless audio in electronic news gathering, documentary, and field production workflows. This A1 variant operates in the 470-516 MHz frequency range, and it is functionally identical to the A-band version in all other respects — same camera-mount form factor, same output cables, same automatic frequency scanning and LCD monitoring.

Choosing the A1 band depends on the RF environment in your operating region. The 470-516 MHz range may offer clearer spectrum in areas where the higher A band (516-558 MHz) is congested by TV broadcast or other wireless users. All transmitters and receivers in the system must share the same frequency band, so the A1 receiver requires A1-band SK 100 G4 or SKM 100 G4 transmitters.

Frequently Asked Questions

Can I use an A1-band receiver with an A-band transmitter?

No. The receiver and transmitter must operate in the same frequency band. An A1 receiver (470-516 MHz) only pairs with A1-band transmitters. They will not tune to frequencies outside their designated range.

Is the A1 band legal in my region?

Frequency availability varies by country and region. Check local regulations regarding UHF wireless microphone spectrum allocation before purchasing. The 470-516 MHz range is commonly available in the United States and many other regions.
