Shure's ULXD2/KSM9 Handheld Transmitter integrates seamlessly with your ULXD2 wireless mic system to deliver clear, uninterrupted 24-bit digital signal transmission over its entire 330-foot operating range.
You can choose between the standard SM58, Beta 58A or 87A, and SM86. Each capsule provides unique benefits.
The Beta58A is a supercardioid, while the 87A is a condenser with a supercardioid polar pattern. The SM86 is a condenser capsule that provides terrific detail and clarity, great for adding intimacy to a vocal performance.
And it can get up to 14 hours of battery life from its AA lithium battery. It’s designed for a quiet startup on band 7 (500.1MHz-530.5MHz), and can use up to 20 wireless channels in the same frequency band at the same time.
Affordability and quality are the main selling points of this wireless mic.
24-bit digital audio and a durable receiver and transmitter make this model a no-brainer if you’re looking for something basic that will just work. It’s an SM58 that transmits at 24-bit/48kHz fidelity.
The automatic frequency detection lets you find a clear channel immediately over its 200 feet of line-of-sight operating range.
It transmits in 2.4GHz at a range of up to 100 feet. There is a built-in windscreen and mode indicator.
An internal gain control takes a bit of finesse to change from the “optimal gain” setting that it comes with initially, but it’s a useful feature.
If you’re looking to get better audio quality for content creation, need an affordable wireless mic for presentations, or want to get your feet wet with how they work at under $100, this option is a great choice.
History of Wireless Microphones
This might come as a shock (it did to me), but wireless microphones have been around since the 1950s!
What won’t surprise you is that Shure and Sennheiser were two of the companies that helped to pioneer the technology.
But there were a number of organizations that were developing and patenting their own designs. These primitive systems only had a range of about 15 feet.
They were also bulky, cumbersome, and ran on large batteries (usually Ds). And to top it off they had a power life of about an hour and a half.
The 1970s is when this technology started to really move forward. Nady, who still makes wireless systems to this day, invented a modality called “companding”.
This essentially compresses the signal before it is sent to the receiver unit.
Across the next decade, the demand for wireless microphones skyrocketed. Musicians, theater, and even the business world all had a unique need for them.
Nowadays wireless mics, like everything else, operate in the digital world. This allows for better audio quality, wider frequency spectrums, and drastically reduced interference.
How Wireless Microphones Work
The concept is similar to a wired microphone. It really just consists of three components: the microphone itself, the wireless transmitter, and the receiver.
The microphone signal is sent to the transmitter. It’s then encoded into a carrier signal that the receiver picks up and decodes.
It then flows into the microphone input of a preamp, mixing console, or interface.
What to Look for in a Wireless Mic for Singing
Budget is always a factor when looking to buy new gear. You need to do your research to make the best purchase decision for what time of price range you’re in.
How Many Mics Can Be Used at Once
Most mid-level systems can operate up to four mics at once without experiencing any signal loss or degradation.
Some are designed for just one, but most allow you to add in more as needed.
Wireless technology runs on two types of frequency ranges – very high frequency (VHF) and ultra-high frequency (UHF).
VHF was the original standard, but since radio stations utilize this range as well it can lead to interference.
UHF is newer and operates at a much higher level. This helps to reduce interference and gives a better sound quality overall.
It’s the antenna that determines how much distance the wireless mic can operate. More antennas on the receiver mean a longer range.
In large sound reinforcement scenarios where there are often hundreds of feet between the stage and the sound booth, multiple antennas can help in reducing dropouts and increase quality.
What makes wireless different than wired?
A lot of them have supercardioid polar patterns since they move around a lot.
Which Bluetooth mic is best for singing?
Bluetooth microphones have come a long way in recent years. While they don’t all offer the best of all features like operating range and noise reduction, there are many models that provide clarity and utility.
The model that offers the best of everything is the Archeer UHF. It’s a dual channel system with just under 100’ of range with a sound quality that will surprise you for the price.
Are wireless microphones any good
Absolutely. They require a little more work to set up than wired microphones do. But the benefits they provide make it worth the extra effort.
Do wireless microphones have worse sound quality?
This is a common misconception – the answer is no! Wireless microphones offer all of the sound quality of wired mics with the added benefit of not being weighed down by wires.
Why are wireless microphones so expensive?
Other than the obvious, there is a lot more technology that goes into their design.
