Shure QLXD24/B87A-X52 QLXD Handheld Wireless Supercardioid Microphone System

The Shure QLXD24/B87A-X52 pairs the Beta 87A supercardioid condenser capsule with Shure's QLXD digital wireless platform, creating a system built for vocalists and presenters who demand studio-level clarity without a cable. The Beta 87A capsule is known for its smooth, detailed frequency response with pronounced presence in the upper midrange — it captures the nuance of a vocalist's delivery, from breathy subtleties to aggressive transients, with a fidelity that dynamic capsules simply do not achieve. The supercardioid pattern provides tighter pickup than a standard cardioid, offering superior rejection of ambient stage noise and adjacent instruments, though it introduces a rear lobe that demands attention to monitor positioning. The QLXD platform transmits 24-bit digital audio across a 300-foot operating range with under 2.9 ms of latency — transparent enough that performers and engineers will not perceive the wireless link in the signal chain.

The X52 frequency band (902-928 MHz) operates in license-free ISM spectrum in the US, and the system's 64 MHz tuning bandwidth with support for up to 17 systems per 6 MHz channel makes it viable for multi-channel installations in houses of worship, corporate AV, touring productions, and broadcast. The receiver features automatic frequency scanning, IR sync with the transmitter, and a half-rack metal chassis with networked control capability. Build quality is consistent with Shure's professional tier — the handheld transmitter feels solid, the receiver withstands rack mounting and transport, and the included accessories (antennas, BNC cables, rackmount kit) cover a complete installation. For engineers who need a wireless vocal system that preserves the sonic character of a premium condenser capsule while delivering reliable RF performance in demanding environments, the QLXD24/B87A sits in the sweet spot between Shure's entry-level BLX line and the flagship Axient Digital platform.
