Using the AKG CGN331 E is easy. First, make sure to connect the microphone to a suitable power source within the 9 - 52 V voltage range. The current requirement is 3 mA, so check your power supply accordingly. Attach the CK31 microphone capsule to the GN30 E gooseneck module firmly. You can then position the gooseneck as you need for the best sound pickup, thanks to its flexible design. When using it, keep in mind that the cardioid polar pattern works best when the sound source is in front of the microphone. This microphone is great for inexperienced speakers, but also handles well when multiple people use it one after another. For maintenance, use a soft, dry cloth to clean the metal body and the microphone capsule regularly. Avoid getting it wet, as this could damage the internal components. Store it in a dry and cool place when not in use. Also, be gentle with the XLR connections to keep the contacts in good condition.
