NDH 20

Tonal Profile

An exemplary datasheet: the sensitivity line names its reference in the label and repeats it in the value, so there is nothing to infer. 114 dB per volt at 150 Ohms means 100 dB costs 0.2 V and 0.27 mW — undemanding despite the high impedance, because the volt scale already accounts for it. Closed, 38 mm, and unusually flat for a sealed design, which is why it turns up on location work rather than only in tracking rooms.
