Older copies of the page and early reviews print 70 Hz to 15 kHz or 50 Hz to 15 kHz, so the maker changed the figure.2Owner's manualhelp.fifinedesign.com/en/articles/13282845-k688-k688t-microphone-user-manual-introductionRead 15 October 2026Specification: Frequency Response 50Hz-16kHz.

Min50 HzMax15 kHz1Maker product pagesamsontech.com/products/microphones/usb-microphones/q2uRead 20 October 2026Specifications: Frequency Response 50Hz-15kHz. The compare table of the same page prints 20Hz-18kHz for the Q2U, which differs. The spec table and the manual agree on 50Hz-15kHz, so that is stored.2Owner's manualstorage.googleapis.com/samson-production/uploads/documents/Q2U_OM_5L_v7.pdfRead 20 October 2026Specifications: Frequency Response 50Hz - 15 kHz.

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.

-50dBV/Pa1Maker product pagefifinemicrophone.com/products/fifine-amplitank-k688-microphoneRead 15 October 2026Spec table: -50±3dBV. The page prints no reference level and no output. The older page and the reviews print -58±3 dB.

-54dBV/Pa1Maker product pagesamsontech.com/products/microphones/usb-microphones/q2uRead 20 October 2026Specifications: Sensitivity -54dBV/Pa. The reference level is not printed and 1 Pa is assumed.2Owner's manualstorage.googleapis.com/samson-production/uploads/documents/Q2U_OM_5L_v7.pdfRead 20 October 2026Specifications: Sensitivity -54 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

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.

130dB SPL1Maker product pagefifinemicrophone.com/products/fifine-amplitank-k688-microphoneRead 15 October 2026The page text says a max SPL of 130dB. No THD level and no output path is printed.

No distortion limit is printed.

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.

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.

Controls and processing

1 of 2 differ

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.

Gain, Headphone volume, Mute1Maker product pagefifinemicrophone.com/products/fifine-amplitank-k688-microphoneRead 15 October 2026Page: tap-to-mute, a gain knob and a monitoring volume control.

Headphone volume, Mute1Maker product pagesamsontech.com/products/microphones/usb-microphones/q2uRead 20 October 2026The headphone output has level control. The On/Off switch controls both the USB and XLR audio output, which the page also calls a microphone mute switch.

The On/Off switch turns the USB and XLR outputs on or off. Input gain is computer-controlled.8Reviewbuzzsprout.com/blog/samson-q2u-reviewRead 20 October 2026No onboard gain knob. A physical off switch mutes between takes. Samson's specs list a headphone level control and an on/off switch.

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.

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.
