The PCC160 is a professional boundary layer microphone and an industry standard stage floor microphone. It's capable of withstanding up to 120dB SPL without distortion. A bass-tilt switch allows the user to tailor the low-end response for particular applications. PCC (Phase Coherent Cardioid) technology uses diaphragms so small that any phase cancellations are above the audible range. This results in a wide, smooth frequency response free of phase interference. The PCC160 uses a supercardioid polar pattern that improves gain before feedback and reduces unwanted room noise from the rear.
