The AKG CM311 is a top - notch reference condenser microphone designed to be worn on the head, ideal for touring and live - sound setups. It delivers a sound quality comparable to the best handheld microphones, offering a full, clear, and distortion - free audio experience, even when used by the loudest singers. The Differoid noise - cancelling technology, which stands for differential cardioid, effectively cancels out ambient noise from floor monitors, crowds, and other sources. Controlled field tests have shown that it provides up to 12dB more gain before feedback than conventional cardioid microphones. Many users report an improved house mix due to the mic's near - complete isolation. Key features include Differoid noise - cancelling, a cardioid polar pattern, a condenser capsule with an internal shock mount, and a robust headband construction. Technical specs: Audio frequency bandwidth is 50 - 17000 Hz, equivalent noise level is 26 dB - A, sensitivity is 1.25 mV/Pa, signal - to - noise ratio is 68 dB - A, electrical impedance is 75 Ohms. The polar pattern is cardioid, and the audio output uses a female 3 - pin Mini XLR connector. Dimensions are 17.76 mm in length, 13.97 mm in width, and 7.62 mm in height, with a net weight of 61 g.
Using the AKG CM311 is easy. First, adjust the headband to fit comfortably on your head. Then, connect the Mini XLR female 3 - pin connector to your audio device. When you start using it, you'll notice how it reduces background noise, giving you a clean sound. As for maintenance, keep it away from moisture and dust. After each use, gently wipe it with a soft cloth. If you're not using it for a long time, store it in a dry and safe place. Make sure to handle it with care, as the internal shock mount can only protect it from minor bumps. When using it in a live - sound setting, test the gain and settings in advance to get the best sound quality.
