Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. Graph "Frequency response" in absolute dB (sensitivity, dBV/Pa: the 0° curve is at about -30 dB at 1 kHz); 20 to 100 kHz shaded on the graph. Distance, room and smoothing not stated.

The manufacturer draws absolute sensitivity (dBV/Pa); shifted here by a constant so 1 kHz is near 0 dB.

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. Each curve drawn on one side only (125 Hz to 1 kHz left, 2 to 32 kHz right); taken as symmetric. Measuring conditions not stated. Approximate some frequencies are identified by reasoning, not by the legend: 125 Hz, 250 Hz, 500 Hz, 1k Hz.

All specs

From the spec sheet
Self-noise10 dB(A). The 2007 instructions add "(DIN 651)".p. 2
Self-noise (CCIR 468)21 dB. The 2007 instructions add "(CCIR 268-3)".
Max SPL138 dB SPL; also 133 dB SPL, with the MZF 8000 II filter module. "Max. SPL"; no THD figure given. The manual calls it "Sound pressure level limit" (page 92).
Rated frequency range10 Hz to 60 kHz; also [30, 50000], 2026 manual; also [10, 70000], 2007 instructions. No tolerance given. The three documents disagree: the 2026 manual says "30 - 50,000 Hz" (page 92), the 2007 instructions "10 Hz – 70 kHz" (page 10).

Modular designMKHC 8020 microphone head (cat. no. 502094) on the MZX 8000 XLR module (502098); the head can be swapped for other 8000-series heads or moved onto extension tubes and remote cablesp. 9
From the manual
Sensitivity−30 dBV/Pa (31 mV/Pa); also −40 dBV/Pa, with the MZF 8000 II filter module. "-30 dBV/Pa (31 mV/Pa) without MZF 8000 II filter module"; "-40 dBV/Pa (10 mV/Pa) with MZF 8000 II filter module" (that module has a -10 dB attenuation switch, page 109). The spec sheet gives the same.p. 92
Weight55 g, approx., with the MZX 8000 XLR module; also 25, microphone head alone. "approx. 25 g", "approx. 55 g with XLR-Modul MZX 8000".
