STAND-BY
With controls set as specified in the section 2-1, input signal from INPUT B of channel 1 and set each output level of MAIN OUT (L,
R), MONITOR OUT and EFFECT OUT to +14 dBu. Then turn on the STAND-BY switch and check the output level is –46 dBu or
less and the STAND-BY indicator lights up.
Note:
• Set the LEVEL control of channels 2 to 11/12 to minimum.
2-16
COMP
2-16-1 GAIN
With controls set as specified in the section 2-1, set the COMP control of channels 1-4 to maximum and the LEVEL control of
channels 1-4 and the MAIN MASTER control to the nominal position. Then check the output level obtained at MAIN OUT L is
within the range specified in the table 2-16-1.
2-16-2 RATIO
Raise the input level by +10 dB and check the output level obtained at MAIN OUT L is within the range specified in the table 2-16-2
compared with the output level specified in the table 2-16-1.
2-16-3 Frequency Characteristic
With the condition specified in the section 2-16-2, set the signal frequency to 20 Hz and 20 kHz and check the output level obtained at
MAIN OUT L is within the range of ±3 dB compared with the 1 kHz (0 dB).
2-16-4 Distortion Factor
With the condition specified in the section 2-16-2, set the signal frequency to 20 Hz, 1 kHz and 20 kHz and check the distortion is less
than the value specified in the table 2-16-4.
Note:
• Distortion should be measured with a 30-kHz low pass filter.
2-16-5 Attack Time and Release Time
With the condition specified in the section 2-16-2, check the attack time and the release time of the output obtained at MAIN OUT L
is within the range specified in the table 2-16-5.
