Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 3. "Figure 1—Frequency Response", relative dB. Distance for the average response not stated (the sheet rates a "far response" of 60-22,000 Hz and says bass is minimal beyond 24 inches); room and smoothing not stated. EV calls it "Average Response" and says each mic's own plot may differ from it. The dotted "Close Response" shows the proximity bass rise; its distance is not printed (the text says maximum bass is "1/4 inch from the sound source").

Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.

Polar pattern

Polar pattern: from the spec sheet, p. 3. "Figure 2—Polar Response", "5 dB per division"; two circles, 500 Hz (left) and 5 kHz and 10 kHz (right), 0° up. Measuring conditions not stated.

From the spec sheet
CapsuleNeodymium-iron-boron (N/DYM) magnet, large reinforced diaphragm, hum-bucking coil, AcoustiDYM shock mount. p. 1: "neodymium-iron-boron magnetic structure", "a large, reinforced diaphragm", "a highly effective hum-bucking coil", "AcoustiDYM™ shock-mount system".p. 1
Sensitivity−50.2 dBV/Pa (3.1 mV/Pa), open circuit, 1 kHz. Not stated by the manufacturer: Converted from "3.1 mV/pascal" (20·log10(0.0031) = -50.2); the 2003 sheet agrees.p. 4
Self-noise14 dB(A), equivalent output noise. "Equivalent Output Noise: 14 dB A weighted (0 dB= 0.00002 pascal)"; the 2003 sheet agrees.
Dynamic range144 dB. "Dynamic Range: 144 dB".
Output impedance150 ohm, balanced (low-Z); also 350 ohm, 2003 Telex sheet. "150 ohms balanced (low–Z)". The 2003 sheet says "350 ohms balanced (low-z)".
Rated frequency range30 Hz to 22 kHz, close response; also [60, 22000], far response. "Frequency Response, Close Response: 30-22,000 Hz; Far Response: 60-22,000 Hz". No tolerance stated.
Weight190 g, net. "Net Weight: 190 g (6.7 oz)"; shipping weight 453 g.
Dimensions115 × 52 mm. "Length: 115 mm (4.5 in.)", "Diameter: 52 mm (2.05 in.)": length, head diameter. Shank 20 mm (0.80 in.).
FinishNon-reflecting black; Memraflex grille screen. "Finish: Nonreflecting black"; "Grill Screen: Memraflex™".
Supplied accessories311 stand clamp; soft zippered gig bag. The 2003 sheet calls the clamp "311 Stand Adapter".
Power level-51 dB at 1 kHz (0 dB = 1 mW/pascal)
PolarityPositive pressure on the diaphragm gives positive voltage on pin 2 with respect to pin 3
Shank20 mm (0.80 in.)
MountingExclusive pivoting yokep. 1
Pop filterAcoustifoam filter built into the removable front grille
Proximity effectMaximum bass with the mic 1/4 inch (about 6 mm) from the source; minimal (normal) bass beyond 24 inches (about 60 cm)
Certificate of PerformanceEach mic's measured response is plotted on a certificate shipped with it; it may differ from the published average responsep. 2
Part numbers534570-9805 (1998 sheet); N/D468 part number 16043008 (2003)p. 4
