What is the primary benefit of the K55 frequency band?

The K55 band provides wide tuning flexibility and a reliable range of frequencies. This is essential for avoiding interference and maintaining secure transmission in demanding RF environments.

How many vocalists can use this system simultaneously?

This specific system is a dual-channel configuration, meaning it includes two handheld transmitters and a dual receiver to support two vocalists at once.

What is the polar pattern of the included Beta 58A microphones?

The Beta 58A features a supercardioid polar pattern. This design provides high rejection of sound from the sides, helping to prevent feedback on loud stages.

Does this system use digital or analogue transmission?

The SLXD+ uses advanced digital wireless technology. This ensures transparent 24-bit audio quality and avoids the noise often found in analogue FM systems.

Can the SLXD+ be managed remotely?

Yes, the system includes features for remote management. This allows sound engineers to monitor status and adjust settings across a network.

How does the Beta 58A differ from the standard SM58?

The Beta 58A has a supercardioid pattern whereas the SM58 is cardioid. The Beta also typically offers a brighter high-end response and higher output sensitivity.

Is the setup process complicated for multi-channel use?

No, the SLXD+ features an automatic setup routine. It can quickly scan for clear frequencies and sync the transmitters to the receiver using an infrared link.

What is the typical price for this dual system?

The typical price for the Shure SLXD+ Dual Wireless Handheld System with Beta 58A K55 is approximately £1,650.

What kind of environments is this system designed for?

It is designed for professional live sound presentations, concert venues, and installed environments like houses of worship or corporate auditoriums.

Is the construction durable enough for touring?

Yes, Shure has designed the SLXD+ with robust construction throughout. It is built to handle the physical demands of regular professional stage use.

Does the system provide secure transmission?

Yes, the digital nature of the SLXD+ provides a secure and stable transmission, reducing the risk of signal drops or external interference.

Can I use other Shure capsules with this system?

While this specific package includes the Beta 58A, the SLXD transmitters feature Shure’s standard interchangeable microphone capsule design, allowing for future flexibility.

Overview

The Shure SLXD+ Dual Wireless system represents an evolution in professional digital wireless technology, specifically configured for environments requiring two concurrent vocal channels. By integrating two handheld transmitters equipped with Beta 58A capsules into a single receiver footprint, the system provides a space-efficient solution for venues and touring engineers. The K55 frequency band offers wide tuning flexibility, which is critical for maintaining signal integrity in increasingly crowded RF environments.

Technology and Features

At the core of the SLXD+ system is Shure's digital wireless technology, which offers 24-bit audio quality and excellent dynamic range. Key features include:

Automatic Setup: Streamlines the deployment process by scanning for open frequencies and syncing transmitters via infrared.
Remote Management: Allows engineers to monitor and control system parameters across a network.
K55 Band Tuning: Provides the necessary bandwidth to support high-channel counts without interference.
Robust Construction: The system is built to withstand the rigours of professional live sound and permanent installation.

Shure SM58 Dynamic Cardioid Vocal Microphone

Sonic Character

The system utilizes the Beta 58A capsule, a significant upgrade over the traditional SM58. The Beta 58A is noted for its supercardioid polar pattern, which provides superior isolation from off-axis noise and high gain before feedback. Sonically, it offers a brightened midrange and a controlled bass roll-off to compensate for proximity effect, ensuring that vocals remain clear and prominent in a dense live mix.

Applications and Suitability

This system is primarily suited for live music venues, houses of worship, and educational institutions where two vocalists or presenters perform simultaneously. Because it operates in a digital format, it avoids the companding artifacts sometimes associated with analogue wireless systems, making it suitable for high-fidelity vocal reproduction. It is an ideal choice for engineers who require a 'plug-and-play' setup that does not sacrifice professional-grade RF stability.

Comparison with Alternatives

When compared to standard analogue systems like the older Shure GLX-D series, the SLXD+ offers greater frequency agility and higher channel counts. While the SM58 capsule is often preferred for its ruggedness and 'warm' legacy sound, the Beta 58A included here provides more detail in the high-frequency range and tighter directional control. For users requiring more complex network integration, the SLXD+ sits below the Axient Digital range but offers a more accessible price point for regional venues and touring acts.
