PF80 pop filter ST305 table stand W4000 external windscreen 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. 2 Description Introduction Contents Optional Accessories Short descriptionP120 P220 15

Description The P120 and P220 share the following features: 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 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: Selector 1 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: Selector 2 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. Features Figure 1: Bass cut and preattenuation switches on microphone front16 P120 P220 Connecting to Audio Equipment

The microphone uses a condenser transducer designed for 48-volt phantom powering to IEC 61938 and needs an external power supply. The microphone provides a balanced output on a 3-pin male XLR connector: Pin 1: ground Pin 2: hot Pin 3: cold Figure 2: Connecting to a balanced input with phantom power

1) Use an XLR cable to connect the microphone to a balanced XLR input

2) Switch the phantom power on. (Refer to the user manual of the unit to

which you connected your microphone.) 3 Connecting to Audio Equipment General Pinout Connecting the MicrophoneP120 P220 17

Operation The P120 and P220 are general-purpose cardioid microphones for recording, broadcast, and onstage use. Every instrument radiates its sound in a specific way. Therefore, to get the best sound it is crucial to experiment with microphone placement. The following hints apply to both the P120 and the P220. The front of the microphone is the side of the body with the AKG logo on it. Therefore, always aim the logo at the sound source you are going to record! Being a unidirectional (cardioid) microphone, the P120/P220 will pick up very little sound from the rear. When recording wind instruments or vocals, make sure not to blow or sing directly into the microphone. To avoid unwanted wind and pop noise or moisture problems, place an optional PF80 pop screen from AKG between the microphone and vocalist/instrument. Keep the microphone dry. Moisture from blowing or singing directly at the capsule from a short distance, or extremely high humidity may cause the microphone to start crackling or go very quiet due to partial short circuits in the polarization voltage. If you use the microphone in the open air, use an optional AKG W4000 windscreen to protect the microphone from moisture and reduce wind noise. High volume instruments: You can use this microphone for close-in recording of very loud instruments (brass instruments, kick drum, etc.). Just switch the preattenuation pad in to increase the microphone's capability of handling sound pressure levels up to 150 dB (P120) or 155 dB (P220). Low-frequency noise: To suppress low-frequency noise such as air conditioning rumble, footfall noise, or traffic sounds, switch the bass cut filter in. 4 Operation Operating instructions Figure 3: Microphone front18 P120 P220 Cleaning Use a soft cloth moistened with water to clean the surface of the microphone body. 5 Cleaning MicrophoneP120 P220 19
