• Target Level: 0 dBu = No gain change.
• Threshold: –16 dBu
° Minimum level required for Auto-Gain operation.
° If the signal is below –16 dB, the gain holds indefinitely.
• Ratio = 3:1
° 3 dB increase or decrease in input level results in 1 dB increase/decrease in output level.
• Turns the gain down at a rate of 32 dB per second.
