3 FB button Switches the gain reduction method between FF (Feed-Forward) circuit and FB (FeedBack) circuit. The button will light when FB circuit is selected. The FF circuit is used in most contemporary compressors. This type is useful when you want to apply consistent compression while maintaining a consistent tonal color. The FB circuit is used in vintage compressors. This type is suitable when you want to apply a smooth compression while adding a tonal character that is characteristic of such devices. 4 GAIN REDUCTION meter Indicates the amount of gain reduction. 5 THRESHOLD knob Adjusts the threshold at which compression starts to be applied. 6 RATIO knob Adjusts the compression ratio. Fully rotate the knob clockwise to switch to the limiter. 7 ATTACK knob Adjusts the compressor's attack time. 8 RELEASE knob Adjusts the compressor's release time. 9 GAIN knob Adjusts the output gain. Graphic EQ, effects, and Premium Rack  U76 U76 is a processor that emulates a popular vintage compressor used in a wide range of situations. This processor does not provide the threshold parameter that is found on conventional compressors. Instead, the intensity of compression is determined by the balance between the input gain and the output gain. The "All mode" setting for the RATIO parameter allows you to create a heavily-compressed sound that is typical of this model. It produces an aggressive tonal character with a rich addition of overtones. 1 2 3 4 56 1 INPUT knob Adjusts the input level. As the input level gets higher, more compression is applied. 2 ATTACK knob Adjusts the compressor's attack time. Fully rotate the knob clockwise to set the fastest attack time. 3 RELEASE knob Adjusts the compressor's release time. Fully rotate the knob clockwise to set the fastest release time. 4 RATIO switch buttons Use these five buttons to set the compression ratio. A button with a higher number will raise the compression ratio more. Pressing the ALL button selects All mode, in which the RATIO will become high, and sharp compression with a faster release time will be applied, creating substantially-distorted aggressive sound. 122 Reference Manual
