Frequency responseiPublished acoustic range of the microphone. A sample rate does not establish it.

Min20 HzMax20 kHz2Owner's manualpubs.shure.com/view/guide/KSM40C/en-US.pdfRead 14 October 2026Specifications: 20 to 20,000 Hz. The frequency response plot is taken 0.6 m (2 ft) from the sound source.8Retailer pagethomann.de/be/shure_ksm40c.htmRead 14 October 2026Frequency range 20 to 20,000 Hz.

Sensitivity (analog)iAnalog output level for 94 dB SPL at 1 kHz, as published in dBV. For a microphone with a switchable preamp, the bypass value is used. A value published only in mV/Pa is converted as 20 x log10(mV/Pa / 1000) and rounded to one decimal, so 1.6 mV/Pa is -55.9 dBV/Pa. The printed value goes in the source note. A sensitivity in plain dB with no reference, as many low-cost USB microphones print it, is left out.

Not available

-33.5dBV/Pa2Owner's manualpubs.shure.com/view/guide/KSM40C/en-US.pdfRead 14 October 2026Open circuit voltage at 1 kHz, typical: -33.5 dBV/Pa (21 mV), 1 Pa = 94 dB SPL.8Retailer pagethomann.de/be/shure_ksm40c.htmRead 14 October 2026Sensitivity -33.5 dBV/Pa.

Sensitivity (digital)iDigital output level over USB for 94 dB SPL at 1 kHz. The minimum gain value is used when several are given. The gain setting goes in the source note. On a USB-only microphone use this field only when the maker prints dBFS or ties a dBV value to the USB output, as Shure does for the MV7i. A dBV, dB re 1 V/Pa or mV/Pa value that names no USB output is left out. The printed unit and the gain go in the source note. A value printed for another reference level is converted by the level difference, so -40 dBFS at 80 dB SPL is -26 dBFS at 94 dB SPL. The printed value goes in the source note.

Not available

Not available

Max SPLiHighest sound pressure level at the source's distortion limit. The THD level and output path go in the source note. The value without a clipping protection mode such as Clipguard is used when both are given. The value with the pad off is used. When the maker lists several preamp loads, the highest load is used. The load goes in the source note. On a USB microphone that prints values per gain setting, the minimum gain value is used, as for sensitivity.

Not available

138dB SPL2Owner's manualpubs.shure.com/view/guide/KSM40C/en-US.pdfRead 14 October 2026Maximum SPL at 1 kHz, 1 percent THD, no pad: 134 dB SPL with a 1000 ohm load and 138 dB SPL with a 2500 or 5000 ohm load. With the 15 dB pad 149 and 153 dB SPL. The 138 dB figure at 2500 ohm without the pad is stored. The guide says the preamp load should be at least 1000 ohm.

Max SPL distortion limitiThe distortion level at which the maker states the max SPL, e.g. 1, 3 or 10 % THD. Left out when the maker names none. Max SPL figures compare only at the same limit.

1%2Owner's manualpubs.shure.com/view/guide/KSM40C/en-US.pdfRead 14 October 2026The maximum SPL table is stated at 1 kHz and 1 percent THD.

Self-noiseiEquivalent noise level, A-weighted, in dB SPL. Lower is quieter. The analog value is used when analog and digital values are both given. A value in dBV or dBFS is left out. On a USB microphone that prints values per gain setting, the minimum gain value is used, as for max SPL.

Output impedanceiRated impedance of the XLR output. For a microphone with a switchable preamp, the bypass value is used. A USB-only microphone has no value here, even when the maker prints an impedance for the capsule. When the maker prints a rated and an actual impedance, as Shure does for the SM58, the rated value is stored and the actual one goes in the source note.

150Ω1Maker product pageelectrovoice.com/product/re20Read 15 October 2026Nominal Impedance: 150 ohms balanced.

Onboard controlsiFunctions you can change on the microphone itself, by knob, button, switch or touch. Settings that exist only in the app do not count. A switch that sets preamp gain steps, such as +18 or +28 dB, counts as gain. Echo is a knob or button for an echo or reverb effect.

Not available

Not available

Onboard processingiProcessing inside the microphone, analog or digital, that works without the maker's app running. A maker statement that settings are saved in the microphone counts. Effects that run only in the app on the computer do not count. An expander counts as noise gate. Clip protection such as Clipguard is clip protection. Limiter is only for a limiter the maker lists as its own effect, never both for one feature. Brand names such as APHEX or Clipguard go in the source note. Attenuation pad is a switch that lowers the capsule output, such as -15 dB. Echo is an echo or reverb effect in the microphone. Exciter or bass enhancer covers effects that add harmonics or bass, such as APHEX Aural Exciter and Big Bottom.

RGB lightingiDecorative lighting. Status and mute lights alone do not count. RGB lighting is lighting with no function. A level meter or mute indicator is not RGB lighting, even when its colour can be chosen. Lighting that changes colour on its own counts, even when it also turns off on mute.

Dimensions and weight

2 of 3 differ

Microphone dimensionsiMicrophone body without a stand or a detachable shock mount. A fixed yoke is included. Width is left to right as seen by the speaker, height is bottom to top in normal use and depth is front to back. Orient the microphone as in use on its yoke or stand. Depth is the direction it points at the speaker, height is up and width is across. An upright side-address microphone has its length as height. An end-address microphone has its length as depth, also when it is held in the hand. A round microphone with only a length and a diameter uses the diameter for the other two sides. The source note states the mapping.

Width54.4Height54.4Depth216.7mm(2.1 × 2.1 × 8.5 in)2Maker spec sheet (PDF)im.static-thomann.de/pics/atg/atgdata/document/manual/233781.pdfRead 15 October 2026Dimensions: length 216.7 mm (8.53 in), widest diameter 54.4 mm (2.14 in), body diameter 49.2 mm (1.94 in). The RE20 is a round end-address microphone used pointing at the speaker, so the 216.7 mm length is the depth and the 54.4 mm widest diameter is both width and height. The body diameter 49.2 mm is not stored.
