2-7. Frequency Characteristics
In the signal routes of the Table 2.6.1 to 2.6.6 indicated with q to o, 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 q, check every OUT when the signal is fed to CH1, and check only the ST L OUT when the signal is fed to CH2
and other channels.
In the route y, check only the ST L OUT and the ST R OUT.
2-8. HPF
In the state of the Table 2.6.1 and 2.6.2, feeding 80 Hz -36dBu signal, and setting the GAIN to MIN, the STEREO L OUT
level obtained when the 80 switch is set to ON shall be within the range of -3 dB +/-2 dB compared to the level obtained
when the switch is set to OFF.
