Electrovoice R300-HD/B

An Electro-Voice solution designed for reliability in live use

The R300-HD/B follows an "efficient and straightforward" approach: a UHF system designed to offer quick setup, smooth operation, and audio quality suited to live performance demands. The presence of preset channels, assistance functions (ClearScan / EZsync), and an antenna diversity receiver make it a relevant choice for providers, bands, and venues seeking a stable solution without unnecessary complexity.

Who benefits from the R300-HD/B and in what applications does it make a difference?

This pack is particularly well-suited for lead vocals, microphone interventions during events, rehearsals, places of worship, conferences, and hosting. The HT-300-B handheld microphone, equipped with a PL22 dynamic capsule and cardioid polar pattern, helps better control feedback and maintain a present voice even when the environment becomes noisy. The Band B frequency range (678 MHz - 694 MHz) will suit users needing a dedicated UHF range: just remember to check compatibility with your area's regulations and radio environment before use.

Key features: simplicity, control, and consistent sound

ClearScan: find a usable channel in seconds

The ClearScan channel selection is designed to speed up choosing a frequency among preset channels. In practice, it saves real time during stage changes, last-minute setups, or installations under real conditions (audience, lighting, other RF links).

EZsync: remote synchronization

EZsync synchronization allows quick pairing of the transmitter and receiver without tedious manual operations. The result: fewer errors, smoother deployment, and more comfortable configuration for both technical teams and independent users.

PL22 dynamic capsule and cardioid polar pattern

The PL22 dynamic capsule, combined with a cardioid polar pattern, targets sound capture focused on the source while further limiting off-axis ambient noise. This is an asset for improving intelligibility and maintaining a usable sound on stage, especially when the microphone is handheld and subject to placement variations.
