The GM301 is a supercardioid classis GM 301 miniature condenser microphone kit in black with the CVE 301.18 power supply.

The GM 301 has specially been designed for the installation into tables or desks and is suitable for use in discussions and tele/video conferences. The 85 mm long gooseneck is provided with a 4-pin female mini XLR connection to connect the microphone to the CVE 301.18 power supply which can be installed into tables or desks and provides a protection against mechanical vibration. If the microphone is not connected, the connection of the CVE 301.18 can be covered with the included covering cap. The GM 301 can also be connected directly to a beltpack transmitter of the Opus wireless systems series and is therefore ideal for lecture rooms, forum discussions or presentations.

The Classis GM 301 microphone features the innovative Scudio™ technology, making the microphone absolutely insensitive to wireless communication devices such as mobile phones.
