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.
7
(HIGH) BOOST knob
Sets the amount of boost applied to the frequency band specified by the HIGH
FREQUENCY knob.
8
(HIGH) ATTEN knob
Sets the amount of attenuation applied to the frequency band specified by the ATTEN
SEL knob.
9
(HIGH) ATTEN SEL knob
Switches the frequency region attenuated by the ATTEN knob.

Dynamic EQ
Dynamic EQ is a newly-developed equalizer that does not emulate any specific model of
equalizer. The sidechain has a filter that extracts the same frequency band as the EQ. This
allows you to apply EQ in the same way as you might apply a compressor or expander to a
specific frequency region, causing the EQ gain to vary dynamically only when a specific
frequency region of the input signal becomes too high or too low. For example you could use
this on a vocal sound as a de-esser, so that EQ is applied to a specific frequency band only
when sibilance or high-frequency consonants reach an unpleasant level, thus preserving a
natural sound that does not impair the original tonal character. Two full-band Dynamic EQs
are provided, enabling you to process a wide range of audio sources.
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
3
Sets the amount of boost applied to the frequency band specified by the LOW
4
FREQUENCY knob.

(LOW) ATTEN knob
6
Sets the amount of attenuation applied to the frequency band specified by the LOW
5
FREQUENCY knob.
5
BAND WIDTH knob
9
Sets the width of the frequency band controlled by the high range filter.
0
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.
