Distance

Frequency response: from the user guide, p. 3. "Typical Frequency Response"; relative dB. Distance, room and smoothing not stated.

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

From the user guide
Sensitivity	−38 dBV/Pa (13 mV/Pa), 1 kHz, open circuit voltage. "Open Circuit Voltage –38.0 dBV/Pa (13 mV)".	p. 3
Rated load impedance	100000 ohm, minimum. "Load Impedance Range: Minimum: 100 kΩ".
Rated frequency range	100 Hz to 5 kHz. The brochure gives "100Hz - 5kHz" too (page 2).
Connector	1/4-inch phone plug on an attached 6.1 m (20 ft) two-conductor shielded cable. "supplied wired for high-impedance, unbalanced connection".
Weight	737 g, with cable. "737 grams (26 oz)".
Dimensions	63 × 82.6 mm. "63 mm (2.5 in) max diameter, 82.6 mm (3 1/4 in) long".
Finish	green and chrome. "Green and chrome finished die casting".
Volume control	Knob at the base of the mic, with an off position	p. 2
Case	Die-cast	p. 3
Polarity	Positive pressure on the diaphragm gives positive voltage on the plug tip
Low-impedance use	Use a low-to-high impedance-matching transformer such as the Shure A95U; the mic can be rewired for low impedance, but that disables the volume control
Replacement parts	R198 cartridge; 95A2353 cable and plug; 90A4487 volume control pot	p. 4
Use (Shure)	Plug straight into a guitar amplifier for the classic blues harp sound; turn the mic volume down before plugging in	p. 2
Impedance	High, unbalanced (no figure given)	p. 3
