Some microphone designs combine several principles in creating the desired polar pattern. This ranges from shielding (meaning diffraction/dissipation/absorption) by the housing itself to electronically combining dual membranes.] cssheader=[boxoverheader] cssbody=[boxoverbody]">Polar Pattern: Cardioid (Unidirectional)--uniform with Frequency, symmetrical about axis
Impedance: Dual. Microphone rating Impedance is 150 Ohms (250 Ohms actual) for connection to Microphone inputs rated at 19 to 300 Ohms and "High" for connection to high-Impedance Microphone inputs. Wired for Low Impedance as supplied. To change Impedance, see sections on lmpedance Selection and Connections in User Guide.
Output Level (at 1,000 ] cssheader=[boxoverheader] cssbody=[boxoverbody]">Hz)
LOW: Open Circuit Voltage* -58.0 dB (1.3 mV)
HIGH: Open Circuit Voltage* -35.0 dB (17.6 mV)
*0 dB = 1 Volt per Pascal (1 PA = 94 dB SPL)
Polarity: Positive pressure on Diaphragm produces positive Voltage on pin 2 (with respect to pin 3).
Switch: Built-in magnetic reed on/off switch with lockplate.
Cartridge Shock Mount: Internal rubber vibration-isolator Swivel Adapter
Positive action, adjustable through 90 degrees from vertical to horizontal, permits easy removal for handheld use, suitable for mounting on stand with 5/8"- 27 thread
