Electro-Voice R300-L-C UHF Wireless Lavalier System / Cardioid Lavalier Microphone / 14 Hour Battery

Description

The R300-L wireless lavalier system delivers a compact UHF wireless solution for speech and performance applications – it pairs a rugged BP-300 metal bodypack transmitter with the directional ULM18 cardioid lavalier microphone. The system is designed to simplify live sound and recording workflows while providing reliable RF performance and durable construction. ClearScan and EZsync streamline setup so operators can get on air quickly and maintain stable operation.

Key features include ClearScan automatic channel selection, EZsync one-step channel setup, and true antenna diversity on the receiver to reduce dropouts. The included ULM18 directional lavalier reduces feedback potential in sound reinforcement environments and improves rejection of off-axis noise. The BP-300 bodypack uses two AA cells and provides a long runtime for extended sessions.

Technically the system offers an audio frequency response of 80 Hz to 18 kHz +/- 2 dB, a dynamic range of 95 dB, and a signal-to-noise ratio of 100 dB – metrics that support clear intelligibility and low noise. RF sensitivity is specified at less than 1.0 uV (12 dB SINAD) and RF output from the transmitter is 8 mW typical. The specified RF frequency range is 16 MHz and distortion is listed as less than 1.0% with 0.4% typical at test conditions.

Connectivity includes balanced XLR output and unbalanced 1/4 inch output on the receiver, plus flexible TNC 1/2 wave antennas for improved reception. The receiver chassis is metal and can be used on a tabletop or mounted in a rack with optional hardware. Controls include On/Off, Set, Up, Down and Sync for straightforward operation.

Common applications include presentations, corporate events, broadcast and theater production where a hands-free microphone is required – the directional lavalier helps maintain clarity on stage. The system is also suitable for location recording of speech and portable sound reinforcement deployments due to its rugged transmitter and long battery life. The multi-channel capability supports deployments where multiple systems operate in the same venue.

Installation and daily use are simplified by EZsync and ClearScan which minimize manual frequency coordination – this reduces setup time and the risk of interference. The metal receiver and transmitter construction offer durability for repeated use and transport, while the user controls and antenna diversity support dependable operation in professional environments. Overall the R300-L balances simple operation with technical performance for speech and live sound applications.
