    R300 Receiver

    With a sleek, low-profile design and durable construction, the R300 receiver system is equally at home on a table top or in a 19-inch equipment rack. Its simple controls and easy-to-read display are designed to provide the ultimate in user-friendly operation. Rack-mount kits and front-mount antenna cables are available for professional installation. For applications with up to four receivers in one rack, the APD4+ antenna splitter can provide antenna and power feeds.

    HT-300 Handheld Transmitter

    The HT-300 metal handheld transmitter is made to withstand the rigors of daily use while being comfortable in the hand. The unit's PL22 dynamic microphone capsule offers the perfect all-around solution for speaking, singing, and emcees. The PL22's cardioid pickup pattern rejects surrounding noise, helping to control feedback while still allowing an experienced vocalist to work the microphone.


    Proven at the highest level of touring and trusted in thousands of installations around the world, Electro-Voice's industry-leading ClearScan system scans through the R300's 32 preset channels and selects the clearest channel - all with the touch of a single button. In an increasingly challenging RF world, ClearScan gives you the confidence to go wireless without worry, ensuring noise-free operation and the longest operating range.


    Matching the R300's transmitter and receiver frequencies is also as simple as the touch of a button. EZsync uses infrared technology to set the transmitter to the correct frequency, confirming operation in one automatic step. Error-free wireless setup has never been easier.
