The Shure QLXD24/B58 system is a versatile and reliable solution designed to meet the demanding needs of performers, presenters, and broadcasters in various settings, ranging from medium-sized venues to corporate facilities. Let’s explore its features and capabilities:

Professional-Quality Audio Transmission

  • UHF Band Operation: Transmitting in the UHF band ensures clear, high-fidelity 24-bit/48 kHz digital audio with accurate low end and crisp transient response.
  • Digital Predictive Switching Diversity: This technology safeguards against interference, ensuring stable RF performance without audio artifacts, even in challenging environments.
  • AES 256-bit Encryption: Provides secure transmission, protecting against unauthorized access and ensuring privacy.

Rugged and User-Friendly Design

  • QLXD2 Handheld Transmitter: Featuring an interchangeable capsule design, it comes equipped with a Beta 58A dynamic capsule with a supercardioid pickup pattern, ideal for speech and vocal performance.
  • Backlit LCD: Offers easy access to essential information and menu options, with the ability to lock settings to prevent accidental changes during use.
  • Adjustable Input Sensitivity: Accommodates various speaking styles and microphone levels for optimal performance.
  • Interchangeable Capsule Design: Allows for flexibility by supporting different Shure capsules to suit specific applications and preferences.

Robust Performance and Intelligent Hardware

  • Digital Switching Diversity Reception: Dynamically switches antennas to prevent dropouts and ensure reliable signal reception.
  • Automatic Frequency Scanning: Simplifies setup by automatically finding and deploying the cleanest frequencies to transmitters via IR sync.
  • Ethernet Networking: Enables real-time monitoring, control, and automatic frequency coordination across multiple receivers using Shure’s Wireless Workbench software.
  • Compatibility: Works seamlessly with external controllers such as AMX and Creston, offering enhanced flexibility and integration options.

Smart Power Management Options

  • SB900A Lithium-Ion Battery: Provides extended transmitter battery life over alkaline batteries, with remaining battery life metering available on the receiver’s front panel.
  • Charging Options: The SB900A battery can be recharged using the SBC charger (sold separately), offering convenient and efficient power management.

Enhanced System Reliability and Expandability

  • Antenna Options: Adding UA874 active antennas or PA805 passive antennas increases system range and offers increased protection against interference.
  • Antenna Distribution System: The UA844+SWB antenna distribution system expands antenna pairs, allowing for more on-air channels in less setup time.
  • Microphone Options: Shure offers a range of bodypack transmitters and microphone options, including lavalier and headset microphones, to adapt the system to different performance needs and preferences.
