User manual AKG PERCEPTION 120 USB QUICK START GUIDE

[. . . ] Designed on the basis of AKG's decades of know-how and feedback from sound engineers around the world using AKG studio microphones every day, these general-purpose 1-inch large-diaphragm microphones bring AKG studio quality to 2 Common Features The PERCEPTION 120 USB and 200 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). 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 135 dB 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 (refer to fig. 1) 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 12 dB/octave from 300 Hz downward. 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. 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 W 4000 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. Low-frequency noise: To suppress low-frequency noise such as air conditioning rumble, footfall noise, or traffic sounds, switch the bass cut filter in. To clean the surface of the microphone body, use a soft cloth moistened with water. Phantom power supply: connect to power outlet or insert battery (batteries). Move microphone further away from sound source. [. . . ] Phantom power supply: connect to power outlet or insert battery (batteries). Move microphone further away from sound source. Place microphone in warm, dry room and allow to dry. [. . . ]
