The PCC®-170SWO is a surface-mounted supercardioid 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 PCC®-170 SWO minimizes background noise and feedback. The microphone reproduces the voice with a clean, clear and natural sound The user can turn the Microphone on and off by pressing a membrane switch on the mic. A pair of extra leads in the Microphone cable allow isolated remote sensing of the microphone switch closure. In a typical distance-learning application, a video camera would track the person who switched on the microphone. The Microphone can be set to be always on. In this mode, the switch only activates the remote sensing and LED. This is useful when using an external gated mixer (automatic mixer). Remote sensing is done by a patented opto-coupled MOS switching circuit. At the remote-sensing leads, the resistance goes low when the Microphone is on. The microphone is attenuated at 70 dB when the switch is off. Since the microphone capsule is placed on a boundary or surface, direct and reflected sounds arrive at the diaphragm in phase.
This coherent addition of direct and reflected waves increases sensitivity by 6 dB and prevents phase cancellations. The Microphone 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. Self-contained electronics eliminate the need for an in-line preamp. Powered by 12-48 V phantom power, the PCC®-170SW has a low-impedance balanced output which permits long cable runs without hum pickup or high-frequency loss. 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.
