Beyerdynamic GM303 12" Cardioid Condenser Gooseneck Microphone, 3-pin XLR-M

The Beyerdynamic Classis GM 303 is a 12" cardioid condenser gooseneck microphone that features a matte black finish and an integrated 3-pin XLR connector.

The gooseneck microphones of the Classis series integrate cardioid electret microphones inside the very small microphone head. They can be used for all kinds of applications where a high-quality, but also discrete microphone is demanded.

Due to the cardioid polar pattern this microphone has a high gain before feedback and provides highest intelligibility of speech. Therefore, the microphones are ideal for the use with lecterns, sound reinforcement applications, conferencing, high quality talkback and paging systems.

All microphones feature the innovative Scudio technology, making the microphones absolutely insensitive to wireless communication devices such as mobile phones.

The microphone is mounted on a 6 mm thick gooseneck and due to its matte black, non-glare surface almost invisible. The microphones can be powered with any phantom power source supplying 8 to 52 volts.

• RFI-proof due to Scudio technology
• High sensitivity
