The best podium mic I've used

Good podium mic. It's own tech combined with a shock mount prevent almost all accidental bass from coming through and allow us to EQ for the voice, not the thumps. Good plosion resistance and amazing side noise rejection. The sound is very natural.

The best podium mic I've used

By ERIC V.

Good podium mic. It's own tech combined with a shock mount prevent almost all accidental bass from coming through and allow us to EQ for the voice, not the thumps. Good plosion resistance and amazing side noise rejection. The sound is very natural.

Under the meticulous design of Countryman, the Isomax 4RF Cardioid Gooseneck Microphone stands out as a premier choice for professionals seeking a durable and high-quality audio solution. The microphone's innovative Active Vibration Isolation technology adeptly detects and eliminates unwanted vibrations from the audio signal, ensuring that table thumps, handling noise, and other disturbances are subtracted, delivering a full, clean sound without the necessity for cumbersome shock mounts.

The Isomax 4RF is engineered with a tightly-controlled cardioid pickup pattern that not only preserves the natural voice quality from any angle but also significantly reduces the likelihood of feedback. This pattern is particularly effective due to its wider front angle, which is optimized to capture sound from small groups while providing maximum rejection of noise sources from behind the microphone, ensuring a clear and focused audio capture.

With an 18-inch tube length, this gooseneck microphone is versatile and well-suited for a broad range of applications, from conference rooms to live performances, where its flush-mount design seamlessly blends into the environment. The flexibility at both ends of the microphone, recommended for the 18-inch and 24-inch lengths, adds to its adaptability, allowing for precise positioning and stable placement.

Crafted by the reputable Countryman brand, known for their professional-grade audio equipment, the Isomax 4RF Cardioid Gooseneck Microphone is a reliable choice for anyone in need of a microphone that delivers consistent, high-quality audio performance with a sleek and unobtrusive design.
