Plug-ins  Controlling the parameters of a plug-in
■ U76
U76 is a processor that emulates a standard vintage compressor used in a wide variety of situations.
It does not provide the threshold parameter that is typically found on a compressor; instead, the
compressor's effect is adjusted by the balance between the input gain and output gain. Setting the
RATIO parameter to "All mode" produces an extremely powerful compression sound that is
considered to be the character of this model. It adds rich overtones that produce an aggressive-
sounding tonal character.

1 INPUT knob
Adjusts the input gain. As the input increases, the compressor's effect also becomes stronger.
2 ATTACK knob
Adjusts the attack time over which the compressor begins to apply. Turning the knob all the
way to the right produces the fastest attack time.
3
RELEASE knob
Adjusts the release time of the compressor. Turning the knob all the way to the right produces
the fastest release time.

4 RATIO switching buttons
Use these five buttons to set the compression ratio.
Buttons with higher numbers produce a higher compression ratio. Pressing the ALL button
selects All mode, which not only raises the RATIO but also makes the release faster, producing
sharp compression with a distorted, aggressive sound.
5 METER switching buttons
Switch the meter display.
• GR .....................The amount of gain reduction applied by the compressor is shown.
• +4/+8 ................With the reference of the output signal level as –18 dB, a value of +4 dB or
+8 dB relative to that reference is shown as 0 VU.
• OFF ...................The meter display is turned off.
6 OUTPUT knob
Adjusts the output level.
If you use the INPUT knob to adjust the amount of gain reduction, the perceptual volume will
also change. In this case, use the OUTPUT knob to adjust the volume.
