AKG / Crown PCC170 SW Professional Boundary Layer Microphone

The PCC®-170SW is a surfacemounted 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 PCC®-170 SW minimizes background noise and feedback. The microphone reproduces the voice with a clean, clear and natural sound.

The PCC®-170SW has a silent-operating membrane switch which is normally off. The switch can be configured for touch on/off, momentary on or momentary off operation. This configuration is set by a bottom-mounted DIP switch. A high-intensity LED lights when the unit is on. The PCC®- 170SW is intended for multiplemicrophone use on a conference table where each person wants control of his or her microphone. The microphone attenuates 70 dB when the switch is in the off position.

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 6 dB and prevents phase cancellations. 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.

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.
