vs 16 clip-on condensers
More output than 53% of 16 clip-on condensers.
Each stripe is one clip-on condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 14 clip-on condensers
Quieter than 0% of 14 clip-on condensers.
Each stripe is one clip-on condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 16 clip-on condensers
Takes louder sound than 53% of 16 clip-on condensers.
Each stripe is one clip-on condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.
Proximity effect: the bass it gains up close
From the spec sheet, p. 2.
"Frequency response" graph, absolute sensitivity in dBV/Pa; legend "1 m, 0°", "1 m, 90°", "1 m, 180°", "10 cm, 0°". 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
From the spec sheet, p. 2. Approximate
Titled "Polar pattern". Each frequency is drawn on one side only (125 to 1000 Hz left, 2000 to 16 000 Hz right); the pattern is taken as symmetric. Measuring conditions not stated.
Approximate: some frequencies are identified by reasoning, not by the legend: 125 Hz.

The 2006 manual and 2009 sheet say 2 kΩ, and the quick guide gives the MZA 900 P a min. load impedance of 5 kΩ (0 dB) or 2 kΩ (-12 dB) (page 2), so 50 Ω looks doubtful. | |
