Shure SM27 Large-Diaphragm Condenser Microphone

<p><strong>Shure SM27 Multi-Purpose Condenser Microphone</strong></p> <p>The SM27 is a rugged and versatile large-diaphragm, side-address cardioid condenser microphone.&nbsp; It has low self-noise and extended frequency response that picks up vocal and instrument nuances with clarity.</p> <p>Durable Shure construction features three separate mesh layers that reduce wind and breath noise. Equally comfortable on stage or in the studio.</p> <p><strong>Shure SM27 Multi-Purpose Condenser Microphone Features :</strong></p> <p>&bull;&nbsp;Uniform cardioid pattern for superior off axis rejection</p> <p>&bull;&nbsp;Superior transient response from a low-mass large Mylar&reg; diaphragm</p> <p>&bull;&nbsp;Flat, neutral frequency response for natural reproduction on stage or in the studio</p> <p>&bull;&nbsp;3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent, extended low-end</p> <p>&bull;&nbsp;Durable metal construction.</p> <p>&bull;&nbsp;Three separate mesh layers reduces wind and breath noise.</p> <p>&bull;&nbsp;15dB pad for performance consistency across a wider range of high SPL sources</p> <p><strong>Shure SM27 Multi-Purpose Condenser Microphone Specifications :</strong></p> <p>&bull; Cartridge type: Externally Biased Condenser</p> <p>&bull;&nbsp;Frequency response: 20 to 20,000Hz</p> <p>&bull;&nbsp;Directional polar pattern: Cardioid</p> <p>&bull;&nbsp;Output impedance: EIA Rated at 150&Omega; (140&Omega; actual)</p> <p>&bull;&nbsp;Attenuation switch: 0 or 15dB attenuation</p> <p>&bull;&nbsp;Low Frequency response switch:</p> <p>&bull;&nbsp;Flat, -6dB/octave below 115Hz, -18dB/octave below 80Hz</p> <p>&bull;&nbsp;Phantom Power: 48 VDC &plusmn;4 VDC (IEC 268 15/DIN 45 596), positive pins 2 and 3</p> <p>&bull;&nbsp;Current drain: 5.4 mA typical at 48 VDC</p> <p>&bull;&nbsp;Common mode rejection: &gt;50dB, 20Hz to 20kHz</p> <p>&bull;&nbsp;Polarity: Positive pressure on diaphragm produces positive voltage on output pin 2 relative to pin 3</p> <p><strong>Dimensions and Weight :</strong></p> <p>&bull;&nbsp;53.0mm (2.08&quot;) maximum body diameter, 156.2mm (6.15&quot;) long; 642g (22.6oz..)</p> <p>&bull;&nbsp;Sensitivity: (typical, at 1000Hz; 1Pa = 94dB SPL): -37dBV/Pa</p> <p>&bull;&nbsp;Self noise (typical, equivalent SPL; A weighted, IEC 651): 9.5dB</p> <p>&bull;&nbsp;Maximum SPL (1000Hz at 1% THD): 2500&Omega; load (Attenuator on): 138 (153)dB, 1000&Omega; load (Attenuator off): 133&nbsp;<span style="font-size:13px; line-height:1.6em">(148)dB</span></p> <p>&bull;&nbsp;Output Clipping Level (20Hz to 20kHz; THD &lt; 1%.
