Plug-ins  Controlling the parameters of a plug-in
■ Opt-2A
Opt-2A is a processor that emulates a standard vintage model of vacuum tube optical compressor.
The level is controlled using optical components such as a CdS-Cell and EL panel to produce
smooth compression. The beautiful high-frequency overtones in the warm distortion created by the
vacuum tube circuit generate an elegant and sophisticated sound.

1 GAIN knob
Adjusts the output level.
2 PEAK REDUCTION knob
Adjusts the compression amount of the signal.
3 RATIO knob
Adjusts the compression ratio.
4 METER SELECT knob
GAIN REDUCTION shows the amount of gain reduction when the compressor is operating.
With the OUTPUT +10 or OUTPUT +4 settings, the output signal level reference is
considered as –18 dB, and a value of +10 dB or +4 dB relative to that reference is shown as
0 VU.

■ EQ-1A
EQ-1A is a processor that emulates a vintage EQ that is considered the classic passive EQ. It uses a
distinctive style of operation, with controllable boost and attenuation (cut) for each of two regions,
low and high. The frequency response is completely different from that of a typical EQ, giving this
model its unique character. The input/output circuit and vacuum tubes also give the sound an
extremely musical character, producing a well-balanced sound.
