Description

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. The LED ring displays the ready-to-talk status of the microphone.

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 mat black, non-glare surface almost invisible. The microphones can be powered with any phantom power source supplying 8 to 52 volts.

With the SP variants you can select via the programmable button between the operating modes ON/OFF, Push-To-Talk and Push-To- Mute. The microphone button can also be disabled. The frequency response can be set with a separate switch in two stages: Linear or with low-cut filter to suppress low-frequency interference. The illuminated ring indicating the microphone status can be deactivated.
