Kommentar des Toningenieurs
Tonal Profile
The FET remake of the U 47 name: cardioid only, a large K47 capsule behind a transformer, and a frequency range Neumann itself quotes as 40 Hz to 16 kHz - narrower than anything else in the current line. It is a loud-source microphone: kick drum, guitar cabinet, brass.
Gain Staging Advice
-42 dBV/Pa with 18 dB-A of self-noise is the quietest-output, noisiest large diaphragm Neumann sells. On a kick drum that is irrelevant; on a voice at a metre it costs you real preamp gain.
Was im Datenblatt tatsächlich steht
Wörtlich von der Herstellerseite zitiert, mit dem Datum der Prüfung. Wir behaupten das Gedruckte, nicht die Absicht dahinter.
«Maximum SPL for THD 0.5% 137 dB / Maximum output voltage -3.3 dBu»
The sign does not survive the arithmetic. 8 mV/Pa driven to 137 dB SPL (43 dB above 1 Pa) is 1.13 V, which is +3.3 dBu; the table prints -3.3 dBu, i.e. 0.53 V. On the neighbouring U 67 sheet the same two rows do agree (-9.8 dBu against 24 mV/Pa at 114 dB SPL), so the identity is Neumann's own.
