Product Description
Shure ADX2FD/K9B Handheld Wireless Microphone Transmitter with KSM9 Capsule - Black
The black Shure ADX2FD/K9B 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/K9B comes equipped with a dual-diaphragm KSM9 condenser capsule that captures sonic nuances with superior detail, delivering precise vocal reproduction for high-end live performance. The KSM9 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 cardioid pattern offers solid gain before feedback, with minimal off-axis coloration, for a warm, full sound. The supercardioid pattern offers increased sound isolation and gain before feedback; an ideal choice for applications where there are high levels of ambient noise, or where multiple instruments or vocalists are close together.
The transmitter operates in a single 146 MHz ultra wide 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/K9B 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.
