The nickel Shure AD2/K11N is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers.

The AD2/K11N comes equipped with a KSM11N condenser capsule featuring a cardioid polar pattern with consistent off-axis rejection that focuses audio capture on the talent and picks up less background noise. The capsule offers an aluminum and steel grille that protects the mic and provides a 3-layer pop filter to help reduce breath and plosive noises. The built-in shockmount helps reduce handling noise during live performance for clearer vocals. The deep cardioid pattern offers solid gain before feedback, with minimal off-axis coloration, for a warm, full sound.

The transmitter operates in a single 146 MHz ultrawide UHF bandwidth with selectable 2/10/35mW RF output power and a transmission range up to 330'. It provides up to 8 hours of operation on two AA batteries and up to 9 hours with an SB900A lithium-ion rechargeable battery (available separately).

With a durable, moisture-resistant, lightweight aluminum case, the AD2/KSM11N transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement applications.

Interchangeable Design with KSM11N Capsule
  • The KSM11N is a proprietary wireless condenser microphone capsule utilizing a 3/4" gold diaphragm and premium electronics for exceptional dynamic range and transient response.
  • The capsule features a highly consistent, deep cardioid polar pattern that reduces off-axis phase distortion for pristinely focused vocal reproduction to provide rich and full low-frequency response, linear and transparent midrange, and natural high-end detail.
  • The dent-resistant, three-stage "pop" protection grille reduces plosives, wind, and other breath noise.
  • The interchangeable capsule design allows you to replace the KSM11N capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, SM58, Beta 58A, Beta 87A, Beta 87C capsules, and more.
User-Friendly Features in a Rugged Housing
  • The unit quickly syncs with a wireless receiver via infrared at the touch of a button.
  • The power button conveniently doubles as mute switch, while preserving RF lock.
  • Frequency and power lockout functions prevent accidental or unauthorized changes during events.
  • A backlit LCD with easy-to-navigate menu and controls lets you quickly access frequency, group, and channel settings, along with mute and lock status, RF output, and remaining battery life.
  • Offset function lets you balance mic levels when assigning multiple transmitters to a single receiver slot. Adjustment range: -12 to +21 dB.
  • 2/10/35mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.
  • Two transmission modes: Standard for optimal coverage with lowest latency and High-Density for maximum system channel count and robust coverage.
Convenient Power Management Options
  • Optional SB900A rechargeable battery offers intelligent power management with precision metering in hours and minutes, and zero memory effect.
  • External charging contacts allow for docked battery charging.
  • SBC220 two-bay and SBC840 eight-bay networked chargers (both available separately) allow for remote power monitoring via Shure’s Wireless Workbench software.

Keeps my coffee as hot as I want it to be
Color: Silver
This coffee warmer is much better than the candle warmer that I was using for my coffee before. With a range of 3 temperatures, I have a choice of temperatures from hot to very, very hot, and the warmer shuts itself off after a while, just in case I forget. The description advises that ceramic cups do not retain heat as well as flat-bottomed cups, but I have not found that to be a problem. Coffee in my ceramic mug stays as hot as I want it to be. The knob on the side makes this warmer easy to turn on and to select a temperature, plus I feel that it is a good value.

Perfect Mug Warmer
Color: Black
I bought this to replace one I'd had for more than 25 years & I'm glad I got this one. Keeps my hot drinks hot for hours & will shut off after that. Quickly heats back up when needed. Very sleek looking. Easy to set up. Just take it out of the box & plug it in.

I love it for my workspace! Hot tea all day
Color: Wood Grain
I love this item. The size is perfect, as I prefer something less bulky for my work desktop. It isn't as fancy as others that has the digital display screen, which is fine by me, because I don't necessarily need that. The knob and different colors that indicate the temperature range works fine. The temperature on this thing works fantastically well for me. Using it on the lowest setting keeps my drink nice and hot in a cold office. I use a heatproof glass teapot with this and its a good fit. It keeps my tea hot throughout the day, so I am able to pour smaller amounts of drink and take my time sipping it throughout the day without worrying that it will get cold. At point I almost forgot that it has an automatic shut-off safety feature when I noticed it was off. So that is a good feature to have. I highly recommend this.

Requires a very specific mug to be useful.
Color: Black
The hotplate itself gets hot enough on its highest setting where it would burn your finger if you left it one there for more then a couple seconds. However when it come to what mug you can use to transfer that heat to your drink, this WILL NOT work with just any old ceramic, metal or glass mugs. You absolutely need to have a perfectly flat bottom on it. If the center of the bottom of the mug does not make direct contact with the very center of the warmer, it will not transfer heat. So straight way plan of spending another $15 to $20. Amazon has some available with good reviews all be it not a very big selection. I'm giving this 4 stars because the description needs to be very clear about this and its not.

Great mug warmer with temp control
Color: Black
I replaced a cheap mug warmer with a couple of these for the house, and for almost the same price this is a lot more functional. I really like the temperature control and silicone surface protector. In combination with the carafe below, this has changed my life - no more microwaving coffee all morning. https://www.amazon.com/GiNT-Stainless-Thermal-Thermos-Retention/dp/B07MW5N7MS
