User manual AKG PERCEPTION 400

[. . . ] Please take a few minutes to read the instructions below carefully before operating the equipment and keep the Manual for future reference. The PERCEPTION 400 is a heavy-duty, rugged true condenser microphone built to the same strict quality standards as all other AKG products. 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, this general-purpose 1-inch large-diaphragm microphone brings AKG studio quality to the worlds of recording, live sound, and broadcasting. [. . . ] The filter rolls off at 12 dB/octave from 300 Hz downward. Neither the diaphragm nor the backplate are permanently polarized, so the microphone needs an external power supply. 2 Pinout The microphone provides a balanced output on a 3-pin male XLR connector: Pin 1: ground Pin 2: hot Pin 3: return Use an XLR cable to connect the microphone to a balanced XLR input with phantom power. (Refer to the user manual of the unit to which you connected your microphone. Every instrument radiates its sound in a specific way. Therefore, to get the best sound it is crucial to experiment with microphone placement. ⷠWhichever polar pattern you selected, it may be good to know which way the transducer axis is facing: the front of the microphone is the side of the body with the AKG logo and polar pattern selector (1) on it. ⷠ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 PERCEPTION 400 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. ⷠIf you use the microphone in the open, 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. 2 Selecting Polar Patterns Each of the PERCEPTION 400's selectable polar patterns is virtually frequency independent so that reflected sound, too will be reproduced accurately and uncolored. [. . . ] 28 mV/Pa (-31 dBV ±2 dB) 20 Hz to 20 kHz (see frequency response graphs) 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. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
