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 confi guration 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, 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 12-48V phantom power, the PCC-170SW has a low-impedance balanced output which permits long cable runs without hum pickup or high-frequency loss. Although the standard connector option is a Switchcraft TB3M, the microphone can be special- ordered with a ¼-inch (6.35-mm) stereo phone plug on the bottom of the base plate as the PCC-170SWSPP.
RFI suppression is included. Self-noise is low and sensitivity is very high. A bass-tilt switch allows the user to tailor the low-end response for particular applications.
Membrane Switch The PCC-170SW membrane switch can be confi gured to work three ways: 1. Touch on/off. Touch the switch to turn on the mic; touch it again to turn off the mic. 2. Momentary on. Touch and hold the switch to turn on the mic momentarily. Release the switch to turn the mic back off. 3. Momentary off. Touch and hold the switch to turn off the mic momentarily. Release the switch to turn the mic back on. This option can serve as a cough or privacy button.
