 "note": "Sensitivity is stored in dB/mW. Where a manufacturer published it per volt it was converted with dB/mW = dB/V - 10*log10(1000/Z); the published value and unit are kept alongside so the conversion can be checked or undone. Amplifier power at loads the maker did not publish is derived by holding output voltage constant between and beyond the published loads, which understates rather than flatters. The basis column says which is which for every figure.",
