Cardioid Polar Pattern
Picks up the most sound in front of the microphone and some from the sides. Less susceptible to feedback in high volume environments.

512“Close-Talk” Microphone

Shure
Dynamic
Simple, rugged diaphragm/coil. handles extreme volume levels without distortion.
Recommended Uses
Video/Broadcast
Podcast/Voiceover

Additional Recommended Uses:

  • Intercom
  • Voice Recognition

Designed for broadcast applications and communication systems. Suitable for environments with high levels of background noise.

Note: For proper operation, mouth-to-microphone distance should be 1 inch (2.5 cm) or less.

  • Frequency response tailored for voice communications
  • Directional microphone element
  • Minimal pick-up of background noise due to close-talk design
  • Earphone on left side only; right side is foam pad
  • Three conductor, shielded, straight cable with connectors
  • XLR male connector for mic; ¼” male phone plug for earphone
  • Does not require DC power for operation

Type
Dynamic, close-talking
 
Frequency Response (at 8 mm 5/16 in.)
50 to 15,000 Hz

Polar Pattern
Cardioid (unidirectional) response ­ uniform with frequency, symmetrical about axis
 
Impedance
Microphone rating impedance is 150 Ohms (200 Ohms actual) for connection to microphone inputs rated at 19 to 300 Ohms.

Output Level (closed-talked at 1,000 Hz)
Open-circuit voltage: -47.0 dB (4.5 mV), 0 dB=1 volt per 100 microbars
Power Level: -66.0 dB, 0 dB=1 milliwatt per 10 microbars
 
Hum Sensitivity (typical)
38.4 dB equivalent SPL in 1 millioersted field

Polarity
Positive pressure on diaphragm produces positive voltage on red lead and pin 2 of connector.

HEADPHONE

Type
Dynamic, open-air, left side only
 
Frequency Response
