(1)

Ratio of output level with 1kHz full-scale sine wave input, to the output level with the inputs short circuited, measured A-weighted over a

20Hz to 20kHz bandwidth using an audio analyzer.

(2)

All performance measurements done with 20kHz 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
