APPLICATIONS
The MPC 23 acoustical boundary microphone is designed for
mounting into tabletops and ceilings. The half-spherical
polar pattern is picked up in a uniform manner. The high
sensitivity guarantees a constant output level even from long
distance sources. Elastic bearing rings achieve mechanical
isolation from the mounting surface and therefore offer
effective sound isolation of the microphone.
The MPC 23 is designed for applications such as tele/video
conferencing, recording or amplification of round table
discussions and wherever the microphone needs to be as
unobtrusive as possible.
FEATURES
• Omnidirectional characteristic (180°coverage)
• Flat, wide frequency response
• High-quality reproduction of speech
• Unobtrusive design
• Ceiling or tabletop mounting
• Fast and easy installation
SUPPLIED ACCESSORIES
• Elastic bearing rings
INSTALLATION
• Mounting hole with elastic bearing rings: Ø 24 mm (15/16")
• Mounting hole with elastic bearing rings: Ø 20 mm (13/16")
• Max. table- /ceiling thickness: 57 mm (2.25")
