WL184 FREQUENCY RESPONSE  
APPLICATIONS  
WL183 (Omnidirectional): General purpose sound reinforcement,  
recording, or remote monitoring applications. Low handling noise. Pickup  
angle is 360°.  
WL184 (Supercardioid): Sound reinforcement applications requiring  
high rejection of ambient noise and narrow pickup angle. Use of wind-  
screen highly recommended. Pickup angle is 115°.  
WL185 (Cardioid): General purpose sound reinforcement applica-  
tions requiring good rejection of ambient noise. Use of windscreen highly  
recommended. Pickup angle is 130°.

The WL183, WL184, and WL185 microphones use interchangeable  
cartridges. To change the cartridge, unscrew it from the microphone base  
and replace it with one of the replacement cartridges listed below.  
Polarity: Positive pressure on diaphragm produces positive voltage  
on pins 3 and 4 relative to pin 1.  
Power Requirements: Regulated nominal +5 Vdc (1.5 Vdc to 10  
Vdc) provided at microphone connector pin 2 relative to pin 1 of a  
Shure wireless microphone transmitter.
