The ISOMAX 4RF’s unique Active Vibration Isolation detects and subtracts table thumps, handling noise, and other vibration from the signal, providing full, clean sound without the need for bulky shock mounts. The ISOMAX 4RF also virtually eliminates buzz from cell phones and other radio frequency (RF) sources, resulting in high-quality, interference-free audio for meeting rooms, houses of worship, and other sound reinforcement and broadcast applications. Its tightly-controlled, consistent pickup pattern accurately captures subjects while reducing feedback.
