GENESIS Radium 300 XLR Black Studio microphone

The GENESIS Radium 300 XLR is a wired studio microphone with cardioid polar pattern designed for clear voice capture and reduced ambient noise. With a sensitivity of -38 dB and a frequency response of 30–16,000 Hz, the microphone delivers high dynamic range and a warm radio-style tone. The package includes a long metal arm, shock mount, pop filter, sponge cover and an XLR-to-3.5 mm cable, making the mic suitable for connection to PCs, laptops and professional studio equipment.

Advantages

The cardioid pickup provides excellent voice clarity and consistent rejection of unwanted background sounds. A built-in pop filter and supplied microphone cover reduce breath noise and plosive consonants while protecting the capsule from dust.

Recommendations

For best results, connect the Radium 300 XLR to a preamplifier or audio interface with proper gain control, maintain a distance of 10–20 cm from the microphone for vocal work, and use the pop filter to minimize plosive sounds. Avoid exposing the microphone to strong air flows and store it covered when not in use to reduce dust buildup.
