System Overview: This microphone is excellent for vocal pickup with its characteristic presence peak. It has a cardioid (unidirectional) polar pickup pattern that minimizes sound pickup from the rear of the microphone. This allows it to be used in close proximity to loudspeakers without creating feedback problems, and it can perform under adverse acoustic conditions where Omni directional microphones cannot. It has a low-impedance balanced output designed for connection to microphone inputs rated at 75 to 300 ohms. The microphone features a cartridge shock mount to reduce stand noise, and On/Off switch, and an attached, self-tensioning, 5/8”-27 thread swivel mount. This microphone is ideal for public address or theater-stage sound systems, as well as for broadcasting, recording, and other sound applications where a stand-mounted microphone with a classic look is desirable. Features:  Uniform cardioid pick-up pattern for maximum gain before feedback and excellent rejection of off-axis sound  Tailored frequency response specifically shaped for speech, vocals and instrumental music  Chrome die-cast metal construction and mechanical design resists wear and abuse  Classic appearance, modern performance  Shock mounted cartridge minimizes stand transmitted noise, ensures quiet operation  Self-tensioning swivel mount permits tilting through 45 degrees forward and 80 degrees backward  On/Off switch  With ruggedness and reliability quality
