The AKG CM311 TA4F is an amazing head-worn condenser microphone perfect for touring and live-sound shows. It delivers a full, clear, and distortion-free sound, just like top handheld mics, even when used by the loudest singers. The Differoid feature, which stands for differential cardioid, effectively cancels out ambient noise from floor monitors, crowds, and other sources. Controlled field tests prove it offers up to 12dB more gain before feedback compared to regular cardioid microphones. Many users find their house mix improves significantly due to the near-complete isolation of this mic. Key features include high ambient noise rejection, excellent gain before feedback, efficient rejection of mechanical and body noise, and maximum comfort and freedom of movement.

Using the AKG CM311 TA4F is easy. First, make sure to properly attach the microphone to your head for a comfortable fit. You can adjust it to find the best position for clear sound. When connecting, use the female 3 - pin TA4F connector. During use, keep in mind that the mic is great at reducing ambient noise, so you can focus on getting a clean sound. For best results, avoid having the mic too close to very loud sources other than your voice. When it comes to maintenance, gently clean the mic with a soft, dry cloth after each use. Store it in a safe place, away from extreme temperatures and humidity. Don't expose it to rough handling as it can affect its performance.
