Shure - ULXD4QE K51

The Shure ULXD4QE K51 Quad-Channel Receiver is the heart of the ULX-D digital wireless system, renowned for its high-quality audio and RF performance.
Designed for professional sound reinforcement applications, it offers a complete range of single, dual and quad-channel transmitters and receivers, all equipped with advanced features and signal encryption for optimum transmission security.

With its advanced digital processing, the ULXD4QE K51 guarantees precise and pure sound reproduction, thanks to an extended frequency response of 20 Hz to 20 kHz and a dynamic range of more than 120 dB.
This technology allows the capture of optimal sound quality with dynamic adjustment of the transmitter gain, whatever the operating conditions.

The ULXD4QE K51 is distinguished by its efficiency and exceptional signal stability, allowing a greater number of active transmitters on the same channel. Compatible with ULXD1, ULXD2, ULXD6 and ULXD8 microphones, it operates in the K51 carrier frequency band (606 to 670 MHz), also benefiting from 2 cascaded BNC connectors in addition to the 2 antenna BNCs, to improve intermodulation performance and allow a large number of receivers in series.

For audio transmission without sound artifacts, the system guarantees a robust RF signal, complemented by AES-256 encryption ensuring total confidentiality in applications requiring high security.

ULXD4 receivers also offer advanced features such as an internal power supply, frequency diversity for beltpack transmitters and Dante digital network connectivity via Ethernet for optimized multichannel audio transmission.

Thanks to the high density mode, the ULXD4QE K51 efficiently manages frequencies even in saturated RF environments, thus ensuring maximum flexibility. Frequency Predictive Diversity prevents signal dropouts due to RF interference or power outages, ensuring smooth, continuous audio performance.

In conclusion, the Shure ULXD4QE K51 Quad Channel Receiver is the equipment of choice for demanding professionals, delivering exceptional performance within the ULX-D system.
