Production Status: In production

The CCRM 4000-RF Plenum is a retractable electret condenser microphone designed for suspended ceiling applications. Its control ports allow DSP connection and daisy chain expansion to other CCRM4000-RF retractable units. Main and secondary units are identical in construction. Two rotary 0-9 digital decimal encoders are used to set the main unit (00) while 01 to 99  determines secondary designation. Up to 99 secondary units can be daisy chained to the Main. The factory default is set to main (00). The XLR socket allows easy and fast connection of the audio to a mixer or DSP processor. A 9-48 Volt phantom power is required. The IR remote control is supplied with the Main unit. It can also be used to activate the units in the absence of a DSP processor. A 2.5 metres audio cable is included. The microphone has a cardioid polar pattern and allows for 350 degree rotation and 40 degree knuckle joint angle. A universal mains switched mode power supply powering up to 4 units is available as a separate item. The microphone features a ceiling bezel with detection switch and an automatic safety detection for cable hang-ups. The CCRM4000-RF is mounted inside a modified Chief CMS491 Plenum rated storage box. It is available in Satin Black or White finish. Nextel Suede coating finishes are for custom orders only. This model is only available in North America.
