The expanded feature set of the ULXP4 wireless receiver offers a direct path to full, clear audio signals.
Advanced settings and controls including lockable settings, automatic frequency selection, group scan function, and predictive diversity. More features below.
- RF Carrier Frequency Range
- 470.000 to 865.000 MHz (Available frequencies depend on the applicable regulations in the country where the system is used). Refer to the frequency supplement supplied with the system.
- Effective Range
- 100 m (300 ft.) under optimal conditions

- Dynamic Range
- >100 dB, A-weighted
- RF Sensitivity
- 1.26 microVolt for 12 dB SINAD (typical)
- Image Rejection
- 80 dB typical
- Spurious Rejection
