The Shure QLXD14/SM35 rackmount digital wireless headset microphone system provides instructors, presenters, and broadcasters with professional-quality audio, reliable RF performance, and secure AES 256-bit encryption. Rugged and easy-to-use, it is ideal for use in TV broadcast or sound-reinforcement applications in medium-sized venues and houses of worship, as well as A/V installations in conference, educational, and corporate facilities.

The QLXD14/SM35 operates in the UHF band to transmit pristine 24-bit/48 kHz digital audio with clarity, accurate low end, and crisp transient response. It utilizes Digital Predictive Switching Diversity to protect the transmission from interference and deliver solid RF signal stability without audio artifacts. You can run up to 60 mic channels at the same location.

The system comes with an SM35 cardioid performance headset microphone built for clear vocal reproduction. The headset's wearable design offers both comfort and a secure fit for long-wearing use and gives active performers the freedom to express themselves without having to sacrifice the sound quality found in traditional microphones. The bodypack transmitter provides up to 9 hours of operation on two AA batteries, with selectable 1/10mW RF power and a transmission range up to 330'.

The receiver features audio and RF meters, 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs. A large LCD screen and intuitive controls let you quickly make adjustments, even in low-light situations. Additional features include automatic frequency scanning, IR sync, and internal limiting to prevent clipping.

The Ethernet port allows multiple receivers to be easily networked together for simplified frequency coordination and deployment via Shure's Wireless Workbench (WWB) software.

The flexible gooseneck design with discrete adjustment options lets you position the microphone for further source isolation in loud environments. 
  • The headset plugs into the locking TA4M connection on the compact QLXD1 bodypack transmitter. The adjustable input sensitivity on the transmitter accommodates a wide variety of speaking styles and mic levels, and even instrument-level audio.
  • The rugged, all-metal transmitter features a backlit LCD that displays essential information and provides fast menu access. It can be locked out to prevent accidental changes during a performance. The transmitter syncs to the receiver via infrared with a quick press on the Sync button.

Robust Performance with Digital Switching Diversity Reception

  • The system operates in the G50: 470 to 534 MHz UHF band with a 64 MHz tuning range and 2560 selectable frequencies.
  • Digital Predictive Switching Diversity uses a microprocessor to switch antennas before dropouts occur.
  • Two detachable 1/2 wave dipole antennas are included.
  • 256-bit AES encryption offers unbreachable privacy by using a unique, randomized encryption key generated every time encryption is enabled.
  • Low latency makes the system ideal for meetings that require live sound reinforcement.

Intelligent Hardware Simplifies Setup, Monitoring, and Control

  • The receiver’s scanning function automatically finds, prioritizes, and deploys the cleanest frequencies to transmitters via IR sync.
  • The receiver offers up to 60 dB of adjustable gain with an internal limiter that automatically engages to prevent digital clipping of your audio.
  • Intuitive front-panel controls with audio and RF LED meters as well as a peak indicator, allow for quick visual checks.
  • Ethernet networking enables real-time, precision monitoring and control of your system as well as automatic frequency coordination across multiple receivers, using Wireless Workbench software (WWB) for Mac/Windows.
  • The system is compatible with external controllers such as AMX and Creston.
  • Remote Control: Make adjustments from anywhere in the venue from your iPad/iPhone via the ShurePlus Channels Mobile App for iOS devices.

Smart Power Management Options

  • Smart Power Management on Transmitter: The SB900A lithium-ion intelligent rechargeable battery with SBC charger (both available separately) provide extended transmitter battery life over alkaline batteries.
  • The SB900A’s remaining battery life can be metered in hours and minutes from the receiver’s front panel.

Enhance the Reliability of Your System

  • Adding UA874 active antennas or PA805 passive antennas increases the range of your system and offers increased protection against interference.
  • The UA844+SWB antenna distribution system (available separately) lets you stretch the power of your antenna pairs, giving you more on-air channels in less setup time.

A Variety of Options to Meet Your Needs

Shure offers numerous lavalier and handheld microphone options to adapt your QLX-D system as your needs evolve.
  • The WL183 (omnidirectional) lavalier mic offers consistent pickup even when the talent turns away from the mic.
  • The WL185 (cardioid) and WL184 (supercardioid) lavalier mics offer narrower, feedback-resistant pickup patterns for louder events.
  • The discrete MX153 sub-miniature earset mic provides exceptional clarity in spoken word applications.
  • The QLXD2 handheld transmitter is available with several mic capsules choices for presenters who prefer the flexibility of a handheld microphone.

One Step Too Far But Otherwise Great
Format: Kindle
Huge fan of this series and the multiverse that it has created. I often find find myself laughing out loud at the irreverent main characters quips. I've been five stars all the way for every book so far but I had to drop a star for a very specific reason. This was the first time I was negatively pulled out of the reading experience in this series. (Though, definitely not the first time lol. That totally random, albeit delicious, recipe for lemonade pulled me out that one rime but it wasn't an unpleasant experience). Spoilers follow: Jason's final words to his dead brother's spirit were so inappropriate and crass that I very much hope this isn't the direction that Jason's character is growing toward. I outwardly cringed and had to put the book down for a few days because I wasn't sure this was a character I wanted to continue to read about after reading those lines. Aside from that it was a great book. I truly hope this was a one-off and simply poorly written vs something we can expect more of going forward. Cringe humor can be funny but there's a limit that was drastically overstepped in that line.

Loved it!
Format: Kindle
There seems to be many books out there now with the fake girlfriend/boyfriend, fake girlfriend/girlfriend, or fake fiance/spouse. I actually like this particular trope quite a lot. Some are OK, bad or good. This novel falls in the last category. I really liked this book and will definitely be re-reading it sometime in the future. Tansy and Gemma are very likeable as individuals. As a couple, they have amazing chemistry very early on. One of the best things I liked about this novel is that the author doesn't make us wait until the end of the book for the characters to acknowledge their attraction. They become a true couple early on despite almost everyone thinking it is not real. The writing is well done and I really really liked the main characters. (Have I said that enough times?) There was definitely some heat too! Everything THIS woman is looking for from a romance novel. Definitely recommend. I give it 4 ¾ stars.

I'm a Total Goner
Format: Kindle
🦇 The Fiancée Farce Book Review 🦇 Rating: ⭐⭐⭐⭐ ❝ She was a total goner. Whatever magic Tansy was made of, Gemma wanted to drown in it, revel in the honeyed heat burning her up from the inside out. It was better than the finest bourbon she’d ever had the pleasure of sipping. ❞ 🦇 After losing her parents and a traumatic romantic experience as a teen, Tansy Adams focuses all her time and energy on her late father's bookstore. To dodge questions about her love life, Tansy invents Gemma, a fake girlfriend inspired by the stunning cover model on a best-selling romance book. She never expected that real-life Gemma would step into her life, play along, and announce they were engaged, imploding that white lie into a full-on farce. Gemma van Dalen, the outcast of her wealthy family, needs a spouse to inherit Van Dalen Publishing; her grandmother's legacy. In exchange for Tansy's hand in marriage, Gemma offers to save Tansy's beloved bookstore before it's sold off. Can their marriage of convenience work, or will Gemma's scheming family get between them? ❝ "As for feeling like you’ve failed, well, failure is an inescapable part of life. But failing doesn’t make you a failure. And I’m sorry your father made you feel like the two were synonymous. You are more than your achievements, Gemma. You are brilliant, and ambitious, and you are good, do you hear me? And what you do or do not achieve in this life has no bearing on your value.” ❞ 💜 Oh. My. Goddess. That's right: goddess, because that's exactly what these two cunning, sassy women are. Alexandria Bellefleur has taken the generally predictable "marriage of convenience" trope and turned it into an emotional, powerful story about finding the love you don't realize you deserve. Both Tansy and Gemma are full of so much pain, their family trees full of broken branches (and in Gemma's case, poisonous barbs). For them to find love and family in one another so unexpectedly (for them, at least, because, come on, that's what we're here for), so flawlessly...it's not only swoon-worthy and sweet, but a relief. It's the insane, instant, undeniable chemistry between Tansy and Gemma that empowers their every interaction from the start, but unlike other marriage-of-convenience stories, smut doesn't drive their relationship. What starts off as a business relationship blossoms from a friendship to a true partnership. Gemma is sweet and giving as she navigates her first real relationship, while Tansy comes out of her shell to defend Gemma when no one else has. These goddesses support one another, even when the relationship is only a farce, until it all becomes real. The character development between them both is a flawless example of how empowering love--and having someone by your side--can really be. 🦇 As much as I loved every interaction between Gemma and Tansy, it's difficult to love everything that happens outside of their sweet sapphic bubble. The toxic men--namely Tucker, Gemma's cousin, who manipulated teenage Tansy and shared underage nudes of her--seem unrealistically cruel. Tansy's step-mother goes from a social ladder-climbing step-Bridzilla to suddenly sympathetic. None of the secondary characters have real layers, making them no more than pawns to the story's plot progression. Because of that, none of the conflicts or twists are surprising. The boardroom scene/resolution seemed beyond unrealistic, regardless of how sweet the gesture was. You may need to expand your suspension of disbelief and focus on the sapphic sweetness for this one. 🦇 Recommended for fans of Stars Collide, Cleat Cute, and Love at First Set. This heartwarming sapphic romance is full of feels; a stunning addition to any shelf. ✨ The Vibes ✨ 🩷 Fake Dating 🩷 Marriage of Convenience 🩷 Bi MCs (Bi4Bi) 🩷 Sapphic Romance 🩷 Mental Health Rep 🩷 Opposites Attract

Thoroughly enjoyed this book. The perfect witty, banter-laden escape, even if predictable for me, which isn’t even that part of the comfort and fun?

okay
Format: Kindle
I’m honestly not sure how i finished this book. i considered dnf-ing multiple times due to boredom, and then did that cycle like 5 times??? So here are your stars, i guess. The plot is bonkers, and somehow was still sooooooo boring to me. Every single twist was painfully obvious, and the chemistry between Tansy and Gemma was saccharine in a very cloying way. The best way i can think to describe this book is having a trope wheel in front of you, spin it 5 times, and write that down. I didn’t hate my reading experience, but i also didn’t *enjoy* it.
