Shure Beta 58A Wireless Vocal System (Analogue)
The Beta 58A dynamic vocal microphone is precision-engineered for live performance and project studio recording. A tailored frequency response accentuates vocals, and the supercardioid pattern isolates from other sound sources. It combines simple setup and an intuitive interface for performance you can trust in.
Shure BLX24UK/B58 Additional Overview:
What is the Beta 58A best suited to? - The Beta 58A is a premium vocal mic ideally suited for professional lead and backup vocals, either on stage or in the studio.
How does this compare to the legendary SM58? - Both are designed for vocal use and have a bright midrange and bass roll-off. The Beta 58A has increased sensitivity and high-end frequency response which results in a cleaner more detailed sound. It also features a supercardioid polar pattern compared to the SM58’s cardioid, giving it greater unwanted sound rejection and more resistance to feedback.
What receiver comes with the Beta Wireless Vocal System? - The Beta Wireless Vocal System comes with the Analog Wireless Receiver BLX4 that provides improved linearity and frequency response.
The receiver BLX is ready to perform right out of the box and is the clearest choice for performers who wish to unplug from the wire. It’s also available as rack mount, metal receiver and Dual Receiver.
How does the BLX receiver perform compared to wired? - The frequency response of the wireless microphone is almost identical to the frequency response of a wired mic. Also the dynamic performance is almost the same.
How many musicians can use this system simultaneously? - Up to 12 compatible channels per group with group and channel scan for easy set-up.
Why internal antennas? - For ideal signal strength, antennas on a wireless system need to be set up in a certain way. The internal antennas on the BLX receiver are already set in this ideal way, offering up to 100 m operating range and optimal signal strength. Additionally internal antennas cannot be broken during setup, use or transport.
Is the setup really that easy? - Yes, with one button you can start the group and channel scan, which gives you the best open frequency. Adjust the transmitter to the same channel and you’re ready to go.
