Key Features & Benefits
🔹 QLXD4 Digital Receiver – True Diversity with Advanced Networking
The half-rack QLXD4 receiver features digital predictive switching True Diversity with four-antenna signal reinforcement, multi-level high-frequency filtering, and short circuit protection. With 100 selectable channels across 50 MHz bandwidth (640–690 MHz), automatic channel scan, and one-touch infrared sync, finding and assigning clear frequencies is effortless. Ethernet networking enables streamlined multi-receiver setup, network channel scanning, and remote control via Shure Wireless Workbench software or the ShurePlus Channels iOS app — plus integration with AMX and Crestron third-party control systems.[reference:0]
🔹 QLXD2 Beta58A Handheld – Legendary Vocal Performance
The QLXD2 handheld transmitter is equipped with the renowned Beta58A supercardioid dynamic capsule, purpose-built for lead vocalists. Its supercardioid polar pattern tightly focuses on the performer's voice while suppressing off-axis noise and feedback. The interchangeable capsule design offers compatibility with the full range of Shure microphone cartridges. Anti-switch impact protection safeguards downstream equipment, while the backlit LCD displays battery status, group/channel, and frequency at a glance.[reference:1][reference:2]
🔹 Extra QLXD1 Bodypack Transmitter – Maximum Versatility
This combo includes an additional QLXD1 beltpack bodypack transmitter at no extra charge — perfect as a backup unit or for presenters who prefer a lavalier or headset configuration. Compatible with a wide selection of Shure lavalier, headset, and instrument microphones via its 4-pin TA4M mini connector. The rugged all-metal bodypack features the same 24-bit digital audio quality, 120 dB dynamic range, AES-256 encryption, and IR sync functionality as the handheld, ensuring seamless integration into your existing QLX-D workflow.[reference:3]
🔹 24-Bit / 48 kHz Digital Audio with 120 dB Dynamic Range
QLX-D delivers transparent 24-bit digital audio with an ultra-wide dynamic range exceeding 120 dB — eliminating the need for transmitter gain adjustments entirely. The extended, flat frequency response of 20 Hz – 20 kHz (microphone dependent) captures every sonic detail, while ultra-low 2.9 ms latency ensures perfect synchronization for live performances. Proprietary gain ranging automatically optimizes the system's dynamic range for any input source.[reference:4]
🔹 Rugged Construction, Extended Battery Life & Secure Transmission
All components feature rugged all-metal construction — machined aluminum handheld and bodypack, steel receiver chassis — built to withstand demanding touring and installation environments. Transmitters deliver up to 9 hours with AA alkaline batteries or up to 10 hours with optional Shure SB900 lithium-ion rechargeable batteries, with accurate remaining runtime displayed in hours and minutes. AES-256 encryption ensures secure, interference-free wireless transmission for sensitive applications. Selectable RF output power (1 mW or 10 mW) allows optimization between range and battery life.[reference:5][reference:6]
