Frequency response

Angle
Distance

Frequency response: from the manual, p. 11. Free field, IEC 60268-4; tolerance ±2 dB (as printed under the graphs). Distance 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 manual, p. 10. Free field, IEC 60268-4. Each curve is drawn on one side only (125 Hz to 1 kHz left, 2 to 16 kHz right); the pattern is taken as symmetric. Rings every 5 dB, centre -25 dB.

From the manual
Sensitivity−42 dBV/Pa (8 mV/Pa), 1 kHz into 1 kohmp. 9
Self-noise17 dB(A), IEC 60268-1, A-weighted RMS. "Equivalent noise level, A-weighted 17 dB-A".
Self-noise (CCIR 468)28 dB, CCIR 468-3 quasi-peak
Max SPL134 dB SPL, less than 0.5% THD; also 140 dB SPL, with pre-attenuation. "Max. SPL for less than 0.5 % THD 134 dB; with preattenuation 140 dB": "THD of microphone amplifier at an input voltage equivalent to the capsule output at the specified SPL".
Signal-to-noise ratio77 dB, re 94 dB SPL, A-weighted; also 66 dB, CCIR
Output impedance150 ohm, rated
Rated load impedance1000 ohm, rated load
Rated frequency range20 Hz to 20 kHz. "Frequency range 20 Hz...20 kHz"; p. 8: "The frequency response of the U 89 i extends below 20 Hz."
Poweringphantom, 48 V ± 4 V (P48, IEC 61938). Any P48 supply giving at least 0.8 mA per channel (p. 7).
Current draw0.8 mA
Low cutoff, 80 Hz, 160 Hz. Rotary switch on the back: "A cutoff frequency of 80 Hz or 160 Hz can be selected"; "When the "LIN" setting is used, a steep low-cut prevents the output transformer from being overloaded by interference below the audio range". "off" here is LIN.p. 7
Pad−6 dB. Switch on the back: ""LIN" or "–6 dB" can be selected". The brief description on p. 6 says the pad "reduces the microphone sensitivity by 10 dB" (also in the German text); the switch label, the 134/140 dB max SPL and the product page ("a switchable 6 dB preattenuation") all say 6 dB. Not shown in the graphs.
ConnectorXLR-3. "Matching connector XLR3F"; balanced transformer output, pin 1 ground, pin 2 +, pin 3 -.p. 9
