Frequency response

Angle
Distance

Frequency response: from the user guide, p. 5. "Frequency Response of DM20 (typical)"; relative dB (+10 to -20). The legend says "5 inches" (the specifications give the range "@ 6” (15cm)"). Room and smoothing not stated.

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. 2. "DM20 Polar Response"; full circle, 0° at the top, rings 5 dB apart from 0 to -30 dB at the centre. Measuring conditions not stated. Approximate reading error up to about 1 dB.

Sensitivity−50 dBV/Pa (3 mV/Pa); also −42 dBV/Pa, 8 mV/Pa, 2020 data sheet and May 2022 guide. "3mV/Pa (-50dBV/Pa)"; the product page says the same. The 2020 data sheet and the May 2022 guide say "8mV/Pa (-42dBV/Pa)".p. 5
Self-noise20 dB(A). "20dB SPL (A weighted)"; the product page: "20dB SPL equivalent (A weighted)".
Max SPL150 dB SPL, peak acoustic input. "Peak Acoustic Input 150dB SPL"; no THD figure.
Rated frequency range20 Hz to 20 kHz, +2 dB at 15 cm. "20Hz to 20kHz +2dB @ 6” (15cm)".
Poweringphantom 24-48 V. "24-48V Phantom,10mA".
Current draw10 mA
ConnectorXLR-3 male (pin 2 +). "XLR (Pin 2+)"; the data sheet: "XLR-3 (pin 2+)".
Weight250 g. ".55lb (.25kg)", as on the product page. The 2020 data sheet prints "0.35 lb. (1.60kg)", which contradicts itself.
Dimensions282 × 22 mm. Length × diameter: "11.12 x .860 inches (282.44mm x 22mm)".

From the product page
Capsulesmall diaphragm, with a Class A amplifier. "A small diaphragm capsule coupled with a proprietary Class A amplifier circuit."p. 1
Signal-to-noise ratio74 dB, A-weighted. "Signal to noise ratio 74dB A-weighted".
Output impedance200 ohm, balanced, between pins 2 & 3. "200Ω balanced (between pins 2 & 3)"; the 2020 data sheet says the same.
Rated load impedance1000 ohm, minimum, between pins 2 & 3. "Min output load 1000Ω between pins 2 & 3", as on the 2020 data sheet. Both guides print "Minimum Output Load 200Ω", which looks like the output impedance under the wrong label.
