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.

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.
5
METER switch buttons
Switch the meter display.
• GR.................Indicates the amount of gain reduction applied by the compressor.
• +4/+8 .............Each meter uses -18 dB as the reference level of the output signal, and
indicates "0VU" for the value of the reference level added by +4 dB or
+8 dB.
• OFF ...............Turns off the meter display.
6
OUTPUT knob
Adjusts the output level.
If you have adjusted the amount of gain reduction by changing the INPUT knob, the
level of audible volume will also change. In this case, use the OUTPUT knob to adjust
the volume level.
◆ Opt-2A
Opt-2A is a processor that emulates a popular vintage model of tube optical compressors. To
control the level, it uses optical components such as a CdS cell and an EL panel to apply
smooth compression, with beautiful high-range overtones generated by warm-sounding
vacuum tube distortion, delivering an elegant and sophisticated sound.
