  • Overview

    The lightweight, durable ESW-T211 UniPak® body-pack transmitter offers superior performance for speakers, instrumentalists and others who need a wearable transmitter. Designed for easy operation, an on-off switch and three-color battery condition indicator are located in plain view. Frequency switches and other setup controls are hidden or recessed to reduce the possibility of unintended mis-adjustment. A premium locking-type audio input connector provides for secure operation. The transmitter accepts microphone-level and instrument-level inputs, and provides the voltage needed to operate electret condenser mics. A variety of Wireless Essentials™ accessory microphone and cables—including clip-on, headworn, boundary and gooseneck mics—are pre-wired to match the transmitter’s input. A recessed high-pass switch permits the rolling off of low frequencies from the microphone.
