Shure SLXD24+/B87A Digital Wireless Handheld System with Beta 87A Supercardioid Condenser Microphone K55

The Beta 87A condenser capsule is engineered for accurate, natural vocal capture with a smooth, extended high-frequency response. Its supercardioid polar pattern delivers excellent isolation from stage noise and monitors, helping vocals remain clear and present in dense mixes. Consistent tonal balance and controlled proximity effect make it a trusted choice for lead vocals in demanding live environments.

Reliable SLXD+ digital wireless platform

Built on Shure’s SLXD+ digital wireless technology, this system delivers 24-bit audio with over 118 dB dynamic range and ultra-low latency. The expanded tuning bandwidth supports a high density of compatible channels, while automatic frequency management maintains clean, stable operation even in congested RF conditions.

ShowLink Ease remote management

ShowLink Ease creates a dedicated control link between the receiver and handheld transmitter, allowing remote adjustment of key parameters. Engineers can change frequencies, adjust gain, deploy new channels in response to interference, and lock controls without interrupting the performer, improving workflow efficiency during live shows.
