2 AGC setting area
AGC (Auto Gain Controller) is a function that automatically compensates the gain
according to the input level, keeping a constant output level for an incoming signal
whose level is changing. For example, differences in how closely and how loudly a
person is speaking into a mic can make their amplified voice vary in volume, making it
less intelligible. In such cases, the volume will be automatically adjusted within a fixed
range.
• AGC [ON] button
Turns AGC on/off.
• [COMPENSATION LEVEL] knob
Specifies the amount of gain compensation. Higher settings will produce more
compensation.
• [RESPONSE TIME] knob
Specifies the response speed for gain compensation. This applies to compensation
that raises the gain; it is the time required for a 6 dB increase.
• [NOISE GATE] button
Turns the noise gate on/off.

Input(dB)
If the input is below the Threshold value, the
output is adjusted so that the output is –18 dB
when it reaches the Threshold value.
If the input is above the Threshold value and
below –18 dB, the output is set to –18 dB.
If the input is above the Threshold value and
above –18 dB, the output level is adjusted by
the Ratio value.
If the noise gate is on, the volume is
adjusted so that input and output are the
same level at –60 dB, and then adjusted so
that the output is –18 dB when it reaches the
Threshold value.
If the input is above the Threshold value and
below –18 dB, the output is set to –18 dB.
If the input is above the Threshold value and
above –18 dB, the output level is adjusted by
the Ratio value.
