From the data sheet rh
Capsulemoving-coil element in a high-mass zinc acoustic chamber, shock-isolated inside the aluminium case; Alnico V magnet. "By use of a high-mass zinc internal acoustic chamber, shock mounted within the machined-aluminum outercasing"; "The magnetic circuit shall be a nonwelded circuit and employ Alnico V and magnetic iron" (p. 2).p. 1
Sensitivity−54.9 dBV/Pa (1.8 mV/Pa), open circuit, 1 kHz; also −55.9 dBV/Pa, product page, "1.6 mV/Pascal", converted. Not stated by the manufacturer: Converted from "Sensitivity, Open Circuit Voltage, 1 kHz: 1.8mV/Pascal" (20·log10 0.0018 = -54.9). The 1997 sheet gives only "Output Level (0 dB = 1 mW/pascal): -55 dB".
Output impedance150 ohm, low-Z, balanced. "Impedance, Low-Z: 150 ohms"; "such that it will match 50-150, and 250-ohms inputs" (p. 2).
Rated frequency range80 Hz to 13 kHz. "80 Hz to 13,000 Hz (see chart)". The graph is drawn from about 40 Hz to 15 kHz.
Poweringnone (passive). "Self generating, no battery or phantom power required".
ConnectorXLR-3 male. "a built-in connector similar or equivalent to the Switchcraft A3M" (p. 2).p. 2
Weight269 g, net. "Net Weight: 269 grams (9.5 oz.)".p. 1
Dimensions197 × 49 × 25 mm. Length × maximum diameter × shank diameter: "Length = 197mm (7.75")", "Max. Diameter = 49mm (1.94")", "Shank Diameter = 25mm (1.0")".
Supplied accessoriesstand adapter (black). "Accessories Included: Stand Adapter (Black)"; optional: 376 charcoal, 379-1 black and 379-2 red windscreens, 422A desk stand (the 1997 sheet: 422A and 423A desk stands).
CaseMachined aluminium outer case, zinc inner casep. 2
Pop and wind filterIntegral windscreen and blast filter; four-stage pop filter keeps dust and magnetic particles from the diaphragm; grille bounces back to its shapep. 1
Handling noise"All handling noise, clothing noise, and even cord shock have been isolated from the microphone element"
PolarityPositive pressure on the element gives positive voltage on the red lead (pin 2) relative to the blue (pin 3)p. 2
Shipping weight539 g (19 oz)p. 1
From the spec sheet 1997 rh
FinishSemi-gloss black (RE50/B); fawn beige (RE50, 1997 sheet). "Finish, RE50/B: Semi-gloss black; RE50: Fawn beige".p. 4
Output level (1997 sheet)-55 dB (0 dB = 1 mW/pascal)
