In the signal routes of the Table 2.6.1 to 2.6.6 indicated with 1 to B, the 20Hz and 20kHz frequency response of each output
shall be within the range of 0 dB +1/ -2.5 dB compared to the 1kHz (0dB).
The 20Hz level when the GAIN volume is Max shall be within the range of 0 dB +1.0/ -4.5 dB compared to the 1kHz (0dB).
In the route 1, check every OUT when the signal is fed to CH1, and check only the ST L OUT when the signal is fed
