[. . . ] Our web address is www. shure. com. 3 General Description The Shure® KSM44A is a premium, large-diaphragm, side-address condenser microphone with multiple polar pattern options (cardioid, omnidirectional, bidirectional). The refined and sophisticated design of the KSM44A features an externally biased, dual 1-inch diaphragms, extensive internal pop filtering and PrethosTM Advanced Preamplifier Technology for a ground-breaking threshold minimum of self-noise. The KSM44A is the premier choice for the highest level of professional studio and stage performance. 4 Features · Multiple polar patterns­cardioid, omnidirectional and bidirectional­for maximum flexibility in a wide variety of recording applications · Dual1inch, externallybiased, ultra-thin, 2. 5m, 24Karatgold-layered, lowmass, Mylar® diaphragms provide superior frequency response · PrethosTM Advanced Preamplifier Technology exhibits extremely low self-noise with superior dynamic range, transient response and ultra-low distortion for transparent recording · Premium electronic components and gold-plated internal and external connectors · Subsonic filter eliminates rumble from mechanical vibration below 17 Hz. · Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs) · 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect · Integrated three-stage "pop" protection grille reduces plosives and other breath noise · Internal shock mount reduces handling and stand noise Performance Characteristics · Extended frequency response · Low self-noise · Exceptional low-frequency reproduction · High output level · Can withstand high sound pressure levels (SPLs) · No crossover distortion · Uniform polar response · Superior common mode rejection and suppression of radio frequency interference (RFI) Applications The KSM44A provides superior results in any application requiring a high quality microphone. [. . . ] Best for picking up room ambience and for miking several sources simultaneously, such as an ensemble or multiple singers. The omnidirectional polar pattern exhibits no proximity effect. Picks up equally from the front and back of the microphone while rejecting sounds from the sides. Often used for stereo recording (such as mid-side and Blumlein techniques). Note: As with all bidirectional microphones, sounds picked up from the back will be out of polarity with the source. Those from the front are in polarity with the source. CAUTION: The switch produces mechanical noise which, when amplified, may damage the loudspeakers. Turn down any loudspeakers or mute the microphone at the mixing console before using the switch. 6 Selecting Low-Frequency Response A three-position switch on the back of the microphone lets you adjust the low-frequency response. Use the low-frequency filter to reduce wind noise, room noise, or proximity effect. Provides the most natural sound in most applications. Provides an 18 dB-per-octave cutoff at 80 Hz. Helps eliminate floor rumble and lowfrequency room noise from heating and air conditioning systems. This setting may also be used to compensate for proximity effect or to reduce low frequencies that make an instrument sound dull or muddy. Provides a 6 dB-per-octave rolloff filter at 115 Hz. Use this to compensate for proximity effect or to reduce low frequencies that could make an instrument sound dull or muddy. +5 dB 0 ­10 20 50 100 2 Flat Response Hz 3 4 5 6 7 89 1000 Low Frequency Cutoff Low Frequency Rolloff Setting Attenuation The attenuation switch lets you reduce the signal level without altering the frequency response. This can prevent extremely loud sounds from overloading the microphone. 0 dB For "quiet" to "normal" sound levels. -15 dB For use with extremely loud sound sources such as drums, horns, or loud guitar cabinets. Load Impedance Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance of the preamplifier to which you connect the microphone.
