SHURE SLXD24E/K8B-J53 (562-606 MHz)

This is a wireless set consisting of the SLXD2 handheld transmitter with a KSM8 dynamic microphone capsule, and the SLXD4 stationary receiver, operating in the frequency range of 562 - 606 MHz.

The SLX-D digital wireless system provides users with more channels than the SLX, smart charging options, and simplified operation at critical moments. It is ideal for use on stage, in classrooms, cultural centers, corporate facilities, hospitality sector, and government facilities, among others. The transmitters operate on 2 standard AA batteries or an optional lithium-ion rechargeable battery with dual or single charging station.

SLX-D is a state-of-the-art system with several noteworthy and user-friendly features and benefits:

• Stable RF transmission — with exceptional signal quality and digital modulation, SLX-D allows users to navigate crowded RF environments with high spectral efficiency and stable RF signal. The system supports up to 32 channels per frequency band without worrying about signal dropouts.

• Excellent sound quality — to ensure flawless performance during every show, lecture, or speech, SLX-D provides crystal-clear audio. With a wide dynamic range, it handles various sources while preventing distortion, ultimately delivering clear and natural sound.

• Ease of use — knowing that staff in various institutions and facilities need a simple and easy-to-use solution, SLX-D is equipped with easy pairing of transmitters and receivers via IR scan and sync, and an automatic frequency search function that allows users to more efficiently set up multiple channels by automatically assigning frequencies to all receivers via Ethernet connection. Even with a 30+ channel system, the entire group scan can be completed in seconds.

DUAL-DIAPHRAGM MICROPHONE KSM8

Patented cartridge design consisting of two ultra-thin diaphragms (one active, one passive) and a groundbreaking inverted airflow system, allowing for unprecedented consistency of the cardioid polar pattern across the entire frequency range. Precise frequency response thanks to controlled proximity effect, resulting in a neutral frequency response in the mid and high ranges, making it the most natural-sounding dynamic microphone. Off-axis signal attenuation allows for unparalleled isolation from unwanted sounds, resulting in increased vocal clarity.
What is the KSM8 best used for?
The KSM8 redefines dynamic microphone technology for leading performers and engineers. It essentially eliminates the proximity effect and provides unmatched vocal accuracy with minimal EQ and processing, designed for use in large, complex sound systems. The KSM8 ensures absolute vocal clarity, suitable for production studios, live performances, and broadcast productions.
KSM8 Characteristics
The KSM8 has an exceptionally wide usable range due to its special Dualdyne cartridge design and its ability to control the proximity effect. Additionally, the neutral mid/high frequency response means no external processing is required, resulting in consistent, natural-sounding audio regardless of the artist's microphone technique.

SLX-D SYSTEM

The SLX-D digital wireless system delivers clear audio, stable RF signal, and is easy to set up. SLX-D is built to handle a wide range of applications, from day-long conferences to nighttime performances.
Automatic channel scan and IR sync are even easier with a guided setup feature programmed into each SLX-D wireless receiver. Manage multiple-system group scans and firmware updates with third-party setup and control via Ethernet. Operate up to 32 compatible systems per 44 MHz band. The transmitter is powered by the most popular AA batteries for up to 8 hours. You can upgrade the power with the optional Shure SB903 lithium-ion rechargeable battery and charging station to accurately monitor remaining runtime in hours and minutes, as well as battery health and other parameters.
