User manual AKG PERCEPTION 120 USB QUICK START GUIDE

[. . . ] Please take a few minutes to read the instructions below carefully before operating the equipment and keep the Manual for future reference. The PERCEPTION 120 USB and PERCEPTION 200 are heavy-duty, rugged true condenser microphones built to the same strict quality standards as all other AKG products. [. . . ] 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. â· 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. 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. To avoid unwanted wind and pop noise or moisture problems, place an optional PF 80 pop screen from AKG between the microphone and vocalist/instrument. 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. â· 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). 1 PERCEPTION 120 USB and PERCEPTION 200 Type: 1-inch large-diaphragm, true condenser pressure-gradient microphone Polar pattern: cardioid Open-circuit sensitivity: 18 mV/Pa (-35 dBV) Frequency range: 20 Hz to 20 kHz (see frequency response trace) Impedance: 200 ohms Recommended load impedance: 1000 ohms Equivalent noise level to CCIR 468-2: 26 dB Equivalent noise level to IEC 60268-4 (A-weighted): 16 dB-A Signal/noise ratio re 1 Pa (A-weighted): 78 dB Max.
