The P120 and P220 are heavy-duty, rugged condenser microphones built to the same strict quality standards as all other AKG products. The P120 uses a 2/3" back electret diaphragm, while the P220 is a true condenser microphone with a 1" large diaphragm. Designed on the basis of AKG's decades of knowhow and feedback from sound engineers around the world using AKG studio microphones every day, these general-purpose microphones bring AKG studio quality to the worlds of recording, live sound, and broadcasting. Founded in 1947, AKG is a divison of Harman and related JBL brands.

• Cardioid polar pattern: The microphone is most sensitive to sounds arriving from in front of it while picking up much less of sounds arriving from the sides or rear (from monitor speakers or neighboring instruments). This makes the microphone equally suited for recording and onstage use
• Gold-sputtered electret diaphragm: The diaphragm is made of a plastic foil that is gold-sputtered on one side only to prevent shorting to the back electrode even at extremely high sound pressure levels
• All-metal body: The all-metal body adds to the rejection of RF interference so you can use the microphone near transmitter stations and along with wireless microphones or other communications equipment. The extremely rugged, heavy body and sturdy front grill protect the microphone from damage from tough handling on stage.
• High headroom, minimum distortion:: Capable of handling sound pressure levels up to 150 dB (P120) or 155 dB (P220) without introducing perceptible distortion and built to resist high temperatures and humidity, the microphone will give excellent results in a wide range of applications.
• Bass cut filter: Switch on the microphone front further reduces low-end distortion caused by footfall or wind noise, etc. The filter also minimizes the proximity effect that close-in miking from less than 4 inches causes in any unidirectional microphone. The filter rolls off at 6 dB/octave (P120) or at 12 dB/octave (P220) from 300 Hz downward.
• Switchable preattenuation pad: Switch on the microphone front lets you increase the headroom by 20 dB for distortionfree close-in recording. The preattenuation pad prevents the microphone's output level, particularly at low frequencies, from overloading the miniature transformers used in many mixer input stages, etc.
