BETA WIRELESS RACK-MOUNT VOCAL SYSTEM WITH BETA 58A

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 in a rack-mount receiver.

BETA 58A CAPSULE

• 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.

BLX2 HANDHELD TRANSMITTER

• Power and battery status LED, Adjustable gain control, Quick and easy frequency matching, up to 14 hours of continuous use, 100 m operating range

BLX4R

• Rack mount Analog Wireless Receiver for up to 12 compatible channels per group with group and channel scan for easy set-up.

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 rack-mount vocal system?

The Beta Wireless Rack-mount Vocal System comes with the Analog Wireless Rack-mount Receiver BLX4R that provides improved linearity and frequency response. The receiver BLX4R is ready to perform right out of the box and is the clearest choice for performers who wish to unplug from the wire.

Is a rack mount kit included

Yes, the box contains everything you need for rack mounting.

How does the blx4r 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.

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.

What does “linearity” mean?

The proportion between input signal of the transmitter and output signal of the receiver is always constant.
