Ratio of output level with 1-kHz full-scale sine-wave input, to the output level with the inputs short-circuited, measured A-weighted over a
20-Hz to 20-kHz bandwidth using an audio analyzer.
All performance measurements done with 20-kHz low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may
result in higher THD+N and lower SNR and dynamic-range readings than shown in the
Electrical Characteristics
. The low-pass filter
removes out-of-band noise, which, although not audible, may affect dynamic specification values.
