Inspection
5.1
gain
The output voltage shall be +22.1 +/- 1dBu when input signal is 1kHz, -10.0dBu.
5.2
Frequency response
Input signals are each 20Hz, 1kHz and 20kHz, -10dBu.
The output voltage shall be 0.0 +/- 0.5dB at 20Hz, -0.5 +/- 0.5dB at 20kHz compared to the 1kHz.
5.3
Distortion Factor
Input signals are each 20Hz and 20kHz.
The distortion shall be less than 0.1% when output voltage as follows.
This inspection should have been finished within 30 seconds.
