Product Overview
The Shure QLXD14/SM35 is a digital wireless headworn microphone system that's part of Shure's QLX-D line of digital wireless systems. QLX-D systems deliver streamlined performance with transparent 24-bit digital audio. Combining professional features with simplified setup and operation, these systems are ideal for mid-size events and installations in businesses, hotels, government offices, schools, houses of worship, and live performance spaces. The SM35 headset offers a secure and comfortable fit. With a tight, unidirectional cardioid polar pattern that rejects signal bleed and feedback, it puts your voice front and center on loud stages. The flexible gooseneck design allows for optimized placement, while the lightweight, low-profile form ensures long-wearing comfort. The tailored frequency response produces clear, crisp vocal reproduction and legendary Shure audio quality.
