b'30 Clockaudio -Ceiling and SuspendedCCRM 4000The ceiling mounted retractable microphone has a wealth of benefits over traditional table mounted microphones. The table is left uncluttered, cables are now hidden in the ceiling and not under the conference room table, the audio from hanging microphones are superior to table mounted microphones as the height can be individually positioned according to the speaker thus allowing for greater signal with less ambient noise. The noise / vibration transmitted across the table from delegates naturally moving laptops or other objects around the table are eliminated by the use of hanging microphones. At the end of the conference the microphones retract back into the ceiling leaving the conference room unspoiled by table mounted microphones.Features: Single element microphone Single element motorised ceiling microphone with cardioid polar pattern for boardrooms,conferencing, courtrooms and other venues)XLR Socket allow easy and fast connection of the audio to mixer or DSP. a 9-48 phantom power supply is requiredThe Retracta can be mounted either horizontally or vertically depending on space and fixing requirement Microphone cable length 2.5 MetresMicrophone is fitted with 350 degree rotationknuckle joint.
