Expert Audio Engineering Commentary
Tonal profile
A dual-output multipattern: the main XLR carries the front diaphragm, a 5-pin mini-XLR carries the rear one, so the pattern can be chosen after the take in software. Everything else is a conventional 1-inch externally polarised condenser.
Gain staging
9 dB(A) at -37.7 dBV/Pa is a good floor for a quiet output. If you use the dual-output mode you need two preamps that match, because any gain difference between them becomes a pattern error, not a level error.
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.
«Sensitivity (all directions) 13 mV/Pa»
This is the well-labelled version of a trap that catches most multi-pattern sheets. Austrian Audio gives one sensitivity for cardioid, omni, figure-8, hypercardioid and every programmable position in between - but says so in the row label. Neumann's TLM 107 and Audio-Technica's AT2050 print a single figure without naming the condition; here the reader at least knows the number is meant to hold across patterns.
