The CROWN PCC®-170 is a surface-mounted supercardioid microphone of professional quality. This handsomely styled unit is appropriate for use on the most elegant boardroom table or lectern. Other applications include churches, courtrooms and council chambers. Because of its highly directional pickup pattern, the CROWN PCC®-170 minimizes background noise and feedback. The microphone reproduces the voice with a clean, clear and natural sound.
The mic capsule is small enough to ensure phase coherency up to the highest frequencies in the audible spectrum, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced. RFI suppression is included. Self-noise is low and sensitivity is very high and an RFI suppression is included. A bass-tilt switch allows the user to tailor the low-end response for particular applications.
Additionally to the features of the CROWN PCC®-170 the CROWN PCC®-170SW/SWO offer a silent-operating membrane switch which is normally off. The switch can be configured for touch on/off, momentary on or momentary off. This configuration is set by a bottom-mounted DIP switch. A high-intensity LED lights when the unit is on. The microphones attenuate 70 dB when the switch is in the off position.
A pair of extra leads in the mic cable allow the CROWN PCC®-170SWO isolated remote sensing of the microphone switch closure. In a typical distance-learning application, a video camera would track to the person who switched on the microphone. Remote sensing is done by a patented opto-coupled MOS switching circuit. At the remote-sensing leads, the resistance goes low when the mic is on. The microphones attenuate 70 dB when the switch is in the off position.
