The Warm Audio WA-47F is a meticulously engineered replication of a renowned classic, incorporating a large-diaphragm FET microphone renowned as a "hidden gem" within elite recording facilities on a global scale. The precursor, the U47 FET, was introduced in 1969 and swiftly gained widespread acclaim, attributable to its exceptional proficiency in accommodating rapid transients and managing elevated sound pressure levels (SPL). This attribute was particularly advantageous for capturing robust kick-drum impacts and imposing guitar/bass cabinet sonorities.The WA-47F features a precision-calibrated frequency response tailored to enhance sound characteristics, and its low-noise circuitry contributes to an unblemished acoustic character, particularly well-suited for solo vocal applications. This meticulous attention to detail ensures that sound is faithfully reproduced, mirroring the sonic nuances of the original model.Warm Audio WA-47F Features:Gold-sputtered, large diaphragm, single-backplate, K47-style capsule for era accurate designHigh-SPL handling (Max 137 dB, or 147 dB with 10 dB engaged) reliably captures kick drum and high-volume sounds without losing fidelityFrequency response of 40 Hz – 16 kHz means wide application with precise pickup capacityCustom TAB-Funkenwerk USA output transformer, premium Fairchild transistors, and wima and polystyrene capacitorsCardioid polar pattern is precise, and pure, ideal for nuanced detailsOutput impedance of 150 ohms, making this microphone low-noise and extremely versatile140 Hz low-cut filter reduces muddiness while keeping low-end tight, retaining substanceRated load impedance of >1k ohmsLightweight, robust design (3.5 lbs / 1.6 kg, mic only: 2 lbs / 0.91 kg)Warm Audio WA-47F Specifications:Microphone Type: FET CondenserPolar Pattern: CardioidDiaphragm Size: LargeFrequency Response: 20 Hz - 19 kHzMax SPL: 137 dB SPLOutput Impedance: 150 ohmsSignal to Noise Ratio: 76 dB A weightedSelf Noise: 18 dB A weightedLow Cut Filter: 140 HzPads: -10 dBConnector: XLRDimensions: 8" x 2.75"Weight: 2 lbs.Included Accessories: Premium Wood Box & Hard Mount Warm Audio WA-47F Large-Diaphragm FET Condenser Microphone.
