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.
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
Switches the meter display.
GAIN REDUCTION indicates the amount of gain reduction applied by the compressor.
With -18 dB as the reference level of the output signal, the OUTPUT +10 and OUTPUT
+4 settings respectively will cause the value +10 dB or +4 dB from this reference level to
be shown as “0VU” on the meter.
EQ-1A
EQ-1A is a processor that emulates a famous passive-type vintage EQ. It features a unique
style of operation, allowing you to individually boost and attenuate (cut) each of two frequency
ranges (high and low). Its frequency response is utterly unlike that of a conventional EQ,
producing a unique character that is distinctive of this model. The input/output circuits and
vacuum tubes produce a tonal character that is highly musical and well-balanced.
1 IN switch
Turns the processor on or off.
When the switch is off, the signal will bypass the filter section, but pass through the
input/output transformer and amp circuits.
2 LOW FREQUENCY knob
Sets the frequency of the low range filter.
3 (LOW) BOOST knob
Sets the amount of boost applied to the frequency band specified by the LOW
FREQUENCY knob.
4 (LOW) ATTEN knob
Sets the amount of attenuation applied to the frequency band specified by the LOW
FREQUENCY knob.
5 BAND WIDTH knob
Sets the width of the frequency band controlled by the high range filter.
As you rotate the knob toward the right (Broad), the band will become wider and the
peak level will decrease. This affects only the response of the boost.
6 HIGH FREQUENCY knob
Sets the frequency of the high range filter. This affects only the response of the boost.
