Product Overview
Transparent 24-bit digital audio and Shure's legendary rock-solid RF performance define the SLXD14/DL4B wireless system with DL4 Lavalier mic. Designed for a range of applications, from extended presentations to live performance, the SLXD14/DL4B offers easy setup and optional rechargeability accessories providing an optimal wireless experience wherever you use it.
You'll get an SLXD4 single-channel receiver, SLXD1 bodypack transmitter, and DL4 omnidirectional lavalier microphone. The DL4 mic carries an IP57 waterproof rating, making it perfect for all-weather use at amusement and water parks or outdoor music venues because the show must go on! Up to 32 compatible systems per 44 MHz band can be operated so the SLXD14/DL4B is ideal as a core system for future expansion.
The SLXD14 DL4B is available in G58, H55, and J52 frequeny band versions.
