Overview

The Shure QLXD4 is a digital half-rack wireless receiver housed in a rugged, full-metal chassis, designed for use with QLXD1 bodypack and QLXD2 handheld transmitters. Offering professional-quality audio, reliable RF performance, and secure AES 256-bit encryption, it is ideal for TV broadcast, sound reinforcement in medium-sized venues, houses of worship, and A/V installations in conference, educational, and corporate facilities.

Key Features:

1. High-Quality Digital Audio:
   • Operates in the G50: 470 to 534 MHz UHF band with a 64 MHz tuning range and 2560 selectable frequencies.
   • Delivers pristine 24-bit/48 kHz digital audio with clear, accurate low end and crisp transient response.
   • Supports up to 60 mic channels at the same location, ensuring versatile and robust performance.
2. Reliable RF Performance:
   • Utilizes Digital Predictive Switching Diversity to protect the transmission from interference and provide solid RF signal stability without audio artifacts.
   • Includes two detachable 1/2 wave dipole antennas.
   • Offers 256-bit AES encryption for unbreachable privacy, using a unique, randomized encryption key generated every time encryption is enabled.
3. User-Friendly Interface:
   • Features audio and RF meters, 60 dB of gain control, and both mic/line XLR and 1/4″ instrument outputs.
   • A large LCD screen and intuitive controls allow for quick adjustments, even in low-light situations.
   • Includes automatic frequency scanning, IR sync, and internal limiting to prevent clipping.
4. Network Integration:
   • Ethernet port allows multiple receivers to be networked together for simplified frequency coordination and deployment via Shure’s Wireless Workbench (WWB) software.
   • Compatible with external controllers such as AMX and Crestron.
   • Supports remote control via the ShurePlus Channels Mobile App for iOS devices, enabling adjustments from anywhere in the venue.
5. Robust Performance and Expandability:
   • Adding UA874 active antennas or PA805 passive antennas increases the system’s range and offers enhanced protection against interference.
   • The UA844+SWB antenna distribution system (available separately) extends the power of your antenna pairs, providing more on-air channels with less setup time.

Compatibility:

• QLXD1 Bodypack Transmitter: Ideal for use with a variety of Shure lavalier, headset, and instrument microphones, providing complete mobility for presenters and performers.
• QLXD2 Handheld Transmitter: Compatible with a wide selection of Shure handheld microphones, offering flexibility for different vocal and speech applications.

Robust Performance with Digital Switching Diversity Reception:

• Digital Predictive Switching Diversity uses a microprocessor to switch antennas before dropouts occur, ensuring reliable RF performance.
• Low latency makes the system ideal for meetings requiring live sound reinforcement.

Intelligent Hardware Simplifies Setup, Monitoring, and Control:

• Scanning function automatically finds, prioritizes, and deploys the cleanest frequencies to transmitters via IR sync.
• Offers up to 60 dB of adjustable gain with an internal limiter that prevents digital clipping.
• Intuitive front-panel controls with audio and RF LED meters, as well as a peak indicator, allow for quick visual checks.
• Ethernet networking enables real-time, precision monitoring and control of your system using Wireless Workbench software for Mac/Windows.
