Expert Audio Engineering Commentary

Tonal Profile

A modular RF condenser: a 19 mm capsule head that screws onto an XLR module, a digital module or a very short extension. Bandwidth runs to 50 kHz, which matters for sound design at pitched-down speeds more than for music.

Gain Staging Advice

-34 dBV/Pa and 13 dB(A) put it within a decibel of the MKH 416 on both counts, in a body a fifth of the length. The 25-ohm source impedance is the practical note: it drives long cable well, but wants a load of at least 1 kilohm.

What the datasheet actually says

Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.

The maker’s own documents disagree
«Connection Wired: no. Value printed: «Connection | Wireless»»

The technical data block of a wired XLR condenser lists «Connection: Wireless», three rows above its own «Audio output: XLR-3M balanced, transformerless, floating» and «Phantom power: 48 V». The sibling MKH 8050 page, built from the same template, prints «Connection: Wired».

One figure, several models
«Sensitivity -34 dBV/Pa»

The cardioid MKH 8040 and the supercardioid MKH 8050 carry the same electro-acoustic block row for row: -34 dBV/Pa, 13 dB(A) and 22 dB CCIR noise, 142 dB SPL, 25 ohms nominal, 1000 ohms minimum load, 3.3 mA, 25 g, 30 Hz - 50 kHz. Only the pickup-pattern row differs.
