Electro-Voice R300-HD/A - UHF Wireless System with PL22 Dynamic Handheld Microphone (A-Band 618–634 MHz)

The Electro-Voice R300-HD/A is a rugged, easy-to-use handheld wireless system that combines the R300 true diversity receiver with the metal-body HT-300 transmitter and PL22 dynamic (cardioid) capsule. Designed for both spoken and vocal vocals, it offers 32 channels per band (up to 8 simultaneous systems ) and quick-setup features like ClearScan (automatic channel search for the cleanest channel) and EZsync (one-step IR sync). It operates in the A-band: 618–634 MHz and provides a system audio response of 80 Hz–18 kHz (±2 dB) with a signal-to-noise ratio >100 dB , ensuring clear, stable sound in events, education, worship, theater and corporate production.

The HT-300 features a metal design with an internal antenna and backlit LCD display (channel, frequency, mute, battery). Powered by 2 AA batteries , it offers a typical runtime of >14 hours with an RF power of 8 mW . The replaceable PL22 capsule is a dynamic cardioid with a response of 80 Hz–12 kHz , a neodymium magnet, 3.2 mV/Pa and 600 Ω , providing vocal clarity and rejection of off-axis sound for greater gain before feedback.
