The blackShure ULXD6/O is a digital tabletop transmitter equipped with an omnidirectional boundary mic and compatible with ULX-D and QLX-D receivers. The omnidirectional polar pattern provides 360° pickup, allowing several speakers at a small table to use a single mic. The unit's low profile is ideal for applications such as video-conferencing where minimum visibility is required. A smart choice for situations where wired mics are impractical, this tabletop transmitter enables quick setup and tear down, and can be put away in a docking station (available separately) for storing and charging when the mic is not in use.
With rugged, yet lightweight plastic housing, the ULXD6/O transmitter delivers pristine 24-bit/48 kHz audio quality and RF performance over its entire 330' range. It offers AES 256-bit encryption for secure transmission and advanced rechargeability options, making it suitable for use in large meetings at conference and convention centers.
User-Friendly Features in a Low-Profile Housing
- The mute button can be configured for momentary or push-on/push-off operation and features a bicolor LED indicating the mute status.
- The unit quickly syncs with a wireless receiver via infrared at the touch of a button.
- The high-pass filter reduces low-frequency noise caused by table vibrations or air-conditioning systems.
- A power lockout function disables the power switch and prevents accidental changes during events.
- 1/10/20mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.
- Low latency makes the ULXD6 ideal for meetings that require live sound reinforcement.
- The transmitter is compatible with the full line of Shure's antenna-distribution components.
Convenient Power Management Options
- The unit operates for up to 8 hours and 40 minutes on two AA batteries.
- An optional Shure SB900A lithium-ion rechargeable battery pack offers intelligent power management with over 9 hours of battery life, precision metering in hours and minutes, and zero memory effect.
- A USB port allows for docked battery charging with the SBC450 (4-bay) and SBC850 (8-bay) networked charging stations (available separately).
- The charging stations enable remote power monitoring via Shure's Wireless Workbench software.

Great chair for everyday use
I’m really happy with this ergonomic chair. It was easy to put together and feels very sturdy once assembled. The mesh back is breathable and keeps my back cool even after sitting for hours. The seat cushion is comfortable and supportive, and the armrests are positioned well for working at a desk. I also like how smoothly the wheels roll and how easy it is to adjust the height. For the price, the quality is honestly better than I expected. I’ve been using it every day for work and it makes long sitting sessions much more comfortable. Definitely a great value and I would recommend it.

Excellent quality, comfortable for 8+ hour days
Color: Grey, Color: Grey
Since the reviews here were so very helpful to me, I decided to leave my own after using this chair a couple days.
To summarize: Overall, I am thrilled with this chair and would recommend! I work remote, in a small apartment and this works well for both space saving and silence when rolling over hardwood floors all day. For more details, read on!
It came packaged very nicely, so everything was well protected during shipping. There are no written instructions and to be honest, I didn't even look for them. If you've put one together before, this is pretty standard. The "leather" (not genuine, but feels like it) is thick and seems it will be sturdy for a long time. The padding is exceptional and that's the main reason I needed a new chair, as mine (a 'basic' brand one, IYKYK) only lasted one year before it felt like sitting on a hard plastic seat. The height is adjustable to go up higher than most, so for once I didn't have to raise it all the way to feel comfy. The surprisingly great thing about it is the arms that flip up, so I can push it all the way under my desk. I live in a small apartment, so every bit of space saved is a bonus! Speaking of apartments, the wheels on this are whisper quiet and I'm more than certain the neighbor below me is thrilled to not hear my clunky wheels from the other chair anymore. I was hesitant to pay too much for an office chair, but given the price and the quality, I feel it was an excellent purchase.
A few items to note, if you have never put one together before: hand tighten the screws first! Don't put them on full force, until the pieces have been mostly assembled. This will help it not come out lopsided and the holes will be a little easier to line up. Watch the video, it will make the process a little easier (unlike what I did - put the arms on correctly, thought that looked wrong, then put them on backwards and lost my mind LOL). The video will also show how to recline the chair, if you like that (I do). It has a recline that's smooth as butter.

Recommend it for all.

Very nice chair. One warning…it went together very easily except for the last screw!!! I finally gave up. A neighbor came over and gave up. My daughter came. Over and after much groaning and moaning got that last screw in.
