2-5 Frequency Response
When the input signal frequency is set to 20 Hz and 20 kHz for the systems shown in table 1, the each output terminal should fall within
the range of +1 and -3 dB at 20 Hz and 20kHz, using 1 kHz as the reference.
2-6 Equalizer Characteristics
When the input signals shown below are applied to the channel input the states of 2-3 and the channel EQ (HIGH, LOW) level control
are changed from center position (flat), the boost/cut range at the MAIN OUT should be as follows:

If the result of the equalizer is out of the specified range, change the input signal frequency so that the output signal is at the set
level. Its frequency should then be within the range of 80 - 120% of the standard frequency.

If the result of the graphic equalizer is out of the specified range, change the input signal frequency so that the output signal is at the set
level. Its frequency should then be within the range of 80 -120% of the standard frequency.
