Shure ADX2 Overview

The nickel Shure ADX2FD/K9HSN is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers. It is ShowLink-enabled for automatic interference avoidance and real-time remote control of parameters. The transmitter also features Frequency Diversity for seamless audio in even the most challenging RF environments.

The ADX2FD/K9HSN comes equipped with a dual-diaphragm KSM9HS condenser capsule that captures sonic nuances with superior detail delivering precise vocal reproduction for high-end live performance. The KSM9HS capsule offers two switchable polar patterns to provide FOH engineers with more choices in dealing with varying environments or the microphone techniques of different performers. The hypercardioid pattern offers excellent off-axis rejection and extended gain before feedback, making it an ideal choice in loud environments. The subcardioid pattern provides a wide coverage angle with subtle off axis-rejection, resulting in a natural sound and minimized proximity effect.

The transmitter operates in a single 146 MHz ultrawide UHF bandwidth. It provides up to 9 hours of operation on an SB920 rechargeable battery, with a transmission range up to 330' and a selectable 2/10/50mW RF output power.

With a durable, moisture-resistant, lightweight aluminum case, the ADX2FD/K9HSN transmitter delivers pristine audio quality, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement applications.

Frequency Diversity for Mission-Critical Applications

  • Frequency Diversity enables simultaneous transmission on two independent frequencies to ensure seamless, uninterrupted audio.
  • Single-carrier mode is available if Frequency Diversity is not required.
  • Switchable RF Power Levels: 2/10/50mW (single-carrier mode) & 2 x 2/10/20mW (Frequency Diversity mode).

ShowLink Enabled for Interference Avoidance & Parameter Control

  • ShowLink technology allows the ADX transmitter to execute an automatic, synchronized frequency change in a matter of milliseconds, ensuring clean, uninterrupted transmission, even in the most challenging RF environments.
  • You can also make instantaneous remote adjustments to your ADX transmitter settings (RF output, gain, mute, and more) when it is difficult or impossible to access the transmitter.

Interchangeable Design with KSM9HS Capsule

  • The KSM9HS capsule with dual 3/4” gold-layered, low-mass Mylar diaphragms provides a consistent frequency response.
  • The mic features a Class-A, discrete transformerless preamplifier for transparency, extremely fast transient response, and no crossover distortion.
  • The integrated three-stage "pop" protection grille reduces plosives, wind, and other breath noise.
  • The interchangeable capsule design allows you to replace the KSM9HS capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, SM58, VP68, Beta 87C, Beta 87A 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.
  • Automatic Gain adjusts the mic input level for you.
  • 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.
  • Two transmission modes: Standard for optimal coverage and High-Density for maximum system channel count and robust coverage.

Convenient Power Management Options

  • Operates for up to 9 hours in single-carrier mode at 10mW on an SB920 rechargeable lithium-ion battery.
  • Runs up to 6.5 hours in Frequency Diversity mode at 10mW x 10mW and up to 5 hours in single-carrier, high-power mode at 50mW.
  • 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.

Good set of clubs for beginners to find out if golf is their game! You'll need a putter, though.
Hand Orientation: Right, Color: Blue/Black
This nice inexpensive set is great for a beginner at golf, which is me--never played before. I don't evem know if I'm going to like playing, but at least I have a set of clubs so that I can give it a try...it's the exercise from walking the course that appeals to me. My son says he can teach me, even using mens clubs. I figure if I like the game, I can get a nicer set of ladies clubs and pass this set to my grandson. If I don't like the game, I can still pass the set along to my grandson! My son thought these clubs were decent weight and quality and well worth the price...the only thing missing was a putter, but we found a cheaper one to add to the set.

Good second-level pickleball paddles for a great price
Color: Black, Color: Black
I've been playing pickleball for a while now, though not ever well. I have progressed from wooden paddles and just trying things out to bundles of basic fiberglass paddles and balls to higher-end paddles that individually cost more than the "multi-paddle plus balls" bundles. I have kids and kids-in-law and grandkids, and not everyone has their own paddles. Thus, I purchased this set to get a couple more paddles. This Amazon Basics set of 2 paddles, four balls, and a carrying case is a starter set, maybe one step up from the basic wooden paddles that I started with. The paddles are nice, light-weight but sturdy, with a decent surface that should allow some level of control. The grips are nice, and there is some additional grip tape you can use to retape a handle that wears out. The balls are standard balls, and should get you started. The case is similar to cases I've purchased before with other sets. Unfortunately, the makers skimped on the zipper. It only has one (another case from a similar set had two zippers), and after just a few uses, the zipper completely fell off (see photo). This makes the case completely useless, and definitely drops my rating. But, given the price, the quality of the paddles, and the four balls, this is still a great starter set, even without a cheap carrying case. I'm happy to have the extra balls and paddles.
