4.3 Frequency Characteristics

In the signal routes of the Table 4.2-1 to 4.2-6 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.

4.4 HPF

In the state of the Table 4.2-1 and 4.2-2, 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/ -2 dB compared to the level obtained
when the switch is set to OFF.
