Description
The Shure ULXD8 Wireless Gooseneck Base Transmitter is a professional desktop wireless microphone base designed for boardrooms, conference rooms, podiums, and panel discussions. Part of Shure’s ULX-D digital wireless platform, the ULXD8 delivers 24-bit digital audio with AES-256 encryption — the same broadcast-quality performance as Shure’s handheld and bodypack transmitters, in a sleek desktop form factor.
