2-5 Frequency Response
When the input signal frequency is set to 20 Hz and 20 kHz in Tables 1, each output terminal level should fall within
the range of +1 and -3 dB, using 1 kHz as the reference.
2-6 Equalizer Characteristics
When LOW, MID, HIGH GAIN VR's of CH1-6 are moved, the output level in each frequency obtained at MAIN OUT
and MONITOR OUT should be in the range shown in the table below, using the output level at the center click position
as reference. If the output level is not within the range as shown in the table, vary the specified frequency of the input
signal within ±20% range and check that the output level as shown in the table below can be obtained.

2-7 Graphic Equalizer Characteristics
When setting of the fader of the graphic equalizer is varied to the maximum and minimum positions, the output response
for each frequency obtained at MAIN OUT and MONITOR OUT should be in the range shown in the table below using
the output level at the center click position as a standard.
If the output level is not within the range as shown in the table, vary the specified frequency of the input signal within
±20% range and check that the output level as shown in the table below can be obtained.
