APPLICATIONS
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 mat black, non-glare surface almost invisible.
The microphones can be powered with any phantom power source
supplying 8 to 52 volts or 48 volts when using microphone versions
with switch.
