SHURE VP88 Sztereó Kondenzátor Mikrofon TypeSingle-point stereo (MS configuration) condenserFrequency Response40 to 20,000 HzPolar PatternMid Cartridge: Cardioid (unidirectional)Side Cartridge: BidirectionalOutput ImpedanceRated at 150 (100 ohms actual). Recommended minimum load impedance: 800 ohms (may be used with loads as low as 150 ohms with reduced clipping level)Sensitivity (1 kHz, MS mode)Open Circuit Voltage: -66 dB (0.5 mV) Mid.

Overvoltage ProtectionMaximum External Voltage applied to Pins 2 through 5 with respect to Pin 1: +/- 75 VdcPolarityPositive pressure applied from any direction to the Mid cartridge or from the left to the Side cartridge in the MS mode, or applied from the front in the Stereo mode produces positive voltage on pin 2 relative to pin 3 (Mid/Left) and pin 4 relative to pin 5 (Side/Right).
