The Shure ULXD2/B58 is a digital handheld wireless microphone transmitter compatible with ULX-D receivers. It comes equipped with a Beta 58A dynamic capsule designed for close-up vocals, with brightened midrange and bass roll-off to control proximity effect. The capsule features a supercardioid polar pattern that ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration.

With a rugged, yet lightweight aluminum housing, the ULXD2/B58 transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options for professional sound-reinforcement applications.

The unit delivers clear, reliable 24-bit/48 kHz digital audio over its entire 330' range, great for live performances and presentations in music venues, houses of worship, and conference spaces.

The hardened steel-mesh grille resists wear and abuse

The interchangeable capsule design allows you to replace the Beta 58A capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, SM58, SM86, SM87A, Beta 87A, Beta 87C capsules, and more.

I loved it so much!!!
Format: Kindle
I've had this one on my TBR lis forever and been meaning to get to it. Considering I picked up the ebook last year not long after it came out. I can't believe I let this one sit on my kindle for as long as I did. I ended up starting and finishing in just one afternoon absolutely hooked on Avery and Knox. They has this connection that just works even if they are to stubborn to see what's happening. I loved the whole bad buy meets the good girl in this sweet steamy enemies to lovers romance. The author does a beautiful job creating a captivating story with characters you can't help falling in love with. This is my first book by the author and I'm a fan as I enjoyed every moment of Avery and Knox's story. I loved that we get to know a little bit of Knox's brothers as the series is about them and can't wait to devour there stories too. Highly recommend the characters are engaging and the story is perfectly balanced with just the right amount of romance. This one made me want to look up the riding that Knox did off season and it's impressive. I loved it!!! One of my favorite books of 2025.

Good Sports Romance
Format: Kindle
Knox is a motor cross racer and Avery is a gymnast. Seems like opposites, right? But there is much more common ground. This couple is fantastic together and love the friends and family vibes. Can’t wait to read the rest of the books in the Holland Brothers series and go back to read Hendrick and Jane’s story.

Holland Brothers Series !!!
Format: Kindle
5/5 ⭐️ 2/5 🌶️ A Holland Brothers Series was exactly what i was hoping for since i read Tempting the Player. Rebecca gave us all exactly what we wanted a Holland brother series and kicked it off with Knox. Knox is the broody, grumpy, closed off, and the 2nd oldest brother who stepped up and held down the fort taking care of the younger brothers after their mom passed and dad stopped coming around but gave up his dreams/ wants in order to do so. With Hendrix, the oldest brother from TTP, back home Knox can go live out his dream as a pro motocross rider. After something goes down between him and his teammate, he’s left without a team and ends up back home and ends up asking the help of a friend of a friend to train him who is Avery. Avery is a college gymnast with two Olympic medals and last season she choked and injured herself before she was able to compete. She’s doesn’t want a distraction but agrees to train Knox which should be easy but it turns out to be anything but that. The banter and argue and then everything changing when his shirt comes off and she spends a little too much time admiring his body in a handstand. These two balanced each other out so well it’s hard to deny even to them. Overall i loved the plot and the character development between these two, the spice, the banter, the nicknames it was all just …..chefs kiss 💋. I cant wait to see which Holland brother Rebecca has in store for us next! 🏍️ Sports Romance 👑 Opposites Attract 🏍️Enemies to Lovers 👑 Train Together 🏍️ Banter 👑 Motorcross x Gymnast 🏍️ Bad Boy x Good Girl

An enjoyable new series with promise
Format: Mass Market Paperback
This is the first in a series. I have already ordered the next one so I like it. The main character Charlie Harris is a widowed library archivist. He lives in his late aunt's house and takes in borders and he owns a Maine coon large cat named Diesel. This is already a somewhat unusual cozy mystery because the main character and devoted cat owner is male. Charlie is a very personable character. He loved his wife (she died of cancer) and his late Aunt. He has 2 grown-up children that he cares about and he likes his job. He gets involved in a murder because his boarder, a young college, student is involved. His archival skills come in handy in providing clues to the murder. The deputy in charge of the investigation is the daughter of his long-time housekeeper. I didn't peek ahead to see who-did-it and I enjoyed the story til the end.. I don't think it's the type of mystery where all the clues are available and the reader tries to figure it out. The reader gets the clues as Charlie . gets them and finds out who the murderer is when Charlie finds out. Yet, the characters are engaging, the setting is interesting and it is a fast and enjoyable read. The plot is credible I like it.
