[제품 스팩] Type Dynamic Frequency Response 50 to 15000 Hz   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 1000 Hz)   Low   High Open Circuit Voltage* -58.0 dB (1.3 mV)   -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 Case Chrome-plated die casting with ARMO-DUR? grille and stainless steel screen Dimensions See User Guide Net Weight (less cable) 255 grams (9 oz)    [제품 설명]   545SD 는 보컬 악기 기타 앰프 등 다양한 용도로 사용하는 단일지향성 다이나믹 마이크 입니다.   1. 예외적으로 일정한 카디오이드(단일지향성) 극성으로 PA 사용시 피드백을 최소화 2. 선택 가능한 이중 임피던스 작동 3. 고정 가능한 magnetic reed 무소음 on/off 스위치 4.
