How the FX550 Works.........................................3
U] Function Configuration............................................3
FX550 functions are divided into three sections: Input control section, Effects section, and Out
put control section. There are also three supporting sections: Operating section, Connecting sec
tion, and Display section.
The Effects section, which applies various effects to the guitar sound, is composed of four
effects (COMP, DIST, EQ, Amp Simulator), and two Effects Sections (MOD and REV). The
MOD section contains 11 effects, and the REV section contains 5 effects. One effect from each
section can be selected at a time.
D+R and D—>R, which are included in the five effects of the REV section, are both a combina
tion of two effects (Delay and Reverb). Selecting D+R or D->R allows you to use seven effects
simultaneously on the FX550.
BYPASS
Configration of the Effects Section
Program
Play Mode
The FX550 can produce up to seven effects simultaneously. A set of effects that can be produced
simultaneously is called a program.
Preset Programs and User Programs
The FX550 has two types of programs: preset programs that have been already set in the factory,
and user programs that can be edited.
50 preset programs (program #1-50) cannot be erased or rewritten.
50 program numbers (51-99 and 00) are reserved for user programs.
All preset programs can be edited, and your new program (edited program) can be stored as a
user program.
The FX550 has three modes: 1 Play mode, 2 Edit mode, and 3 Utility mode.
Play mode: This is the main mode of the FX550. It provides the effects for guitar performance.
Chapter 2 explains this mode.
Edit mode: This is a sub-mode that supports Play mode. In this mode, you may edit and prepare
the programs to be used in Play mode. To “edit” means to change the effect parameter settings.
Utility mode: This is also a sub-mode that supports Play mode. This mode allows you to specify
the settings for the operational controls, and supports portions of Edit mode, such as titling the
programs. Chapters 4 and 5 cover this mode.
Use the mode buttons to select modes. The unit is always set to Play mode when the power is
initially turned on.

chapter 4: Effect parameters
Compressor/Limiter — COMP
The compressor/Limiter effect section reduces the level of loud sounds and increases the level of
quiet sounds, making the volume level more consistent (reduced dynamic range). In addition,
sounds are sustained. Compressors are often used when recording guitars, a reduced dynamic
range makes it much easier to set recording levels.
Distortion/Overdrive — DIST
Distortion is one of the most widely used guitar effects and is an essential part of rock music.
The FX550’s distortion/overdrive effect section produces a smooth, rich powerful distortion that
rivals that of the best valve amps. Many types of distortion effect can be produced, everything
from soft overdrive to hard distortion. This effect also includes a noise gate that can be used to
attenuate unwanted hiss and noise while you are not playing.
Higher values produce a sharp bright sound.
Sets the output level of the effect.
The level at which the noise gate cuts in.

Chapter 4: Effect parameters
3-Band Parametric Equalizer — EQ
The EQ effect section features a 3-band equalizer, each band having boost/cut control and vari
able frequency selection. The Mid EQ provides up to 30 dB of cut and can be used as a notch
filter.

The modulation effect section can produce 11 different types of modulation effect.
The chorus effect splits the signal into two, modulates one signal, then mixes the two signals
together. It produces a rich thickening type effect — like a chorus of guitars playing together.
The stereo flanger effect splits the signal into two, delays one signal by a modulated delay time,
then mixes the signals together. It produces a comb filter effect that sweeps up an down the audio
bandwidth. Sometimes described as a swishing or tunneling effect, it is a coarse form of phaser
effect.
The symphonic effect splits the signal into two, modulates one signal, then mixes the two signals
together. It produces a rich thickening type effect, similar to a chorus effect — like a symphony
of guitars playing together.

The auto pan effect moves the signal continuously across the stereo image, i.e., between the left
and right outputs. It provides a drifting type effect that is ideal for slow atmospheric songs and
can help to maintain interest in repetitive guitar riffs. The panning speed is controlled by the
modulation speed parameter.

The tremolo effect modulates the signal amplitude to produce regular variations in volume level,
similar to vocal vibrato. The modulation waveform can be set to sine, triangular, or square,
offering three tremolo effect variations.
This effect was originally produced by rotating a flat piece of wood in front of the loudspeaker in
an organ. There are two rotation speeds: slow and fast.
The SPD parameter can set using a foot switch. See page 28.
Tempo Modulation — TMD
The tempo modulation effect can produce flanger, tremolo, and pan type effects. The difference
between this effect and the other flanger and pan effects is that the modulation speed can be syn
chronized to the song tempo. This can be set manually in bpm (beats per minute), from a MIDI
sequencer or drum machine using MIDI clock messages, or by tapping a foot switch.

The signal that is fed back will, obviously, be
pitch shifted again, and again.
The ping-pong delay effect delays the signal, then outputs the signal to the left and right outputs
alternately, so the delayed signal appears to bounce across the stereo image.

Stereo Modulation Delay — SMD
The stereo modulation delay effect delays the left and right output signals using different delay
times, then modulates both delay times. It produces a rich stereo thickening effect, similar to
chorus hut with two independent delays and feedback parameter.

- -30 dB - +6 dB
The amount of effected signal that is fed
back into the effect.
If the DLYL and DLYR parameters are set to
the same (or similar) delay times, this effect
may sound like a signal phasing problem. If
so, adjust the L/R parameter to correct it.
The delay time of tempo delay effect can be synchronized to the song tempo. This can be set
manually in bpm (beats per minute), from a MIDI sequencer or drum machine using MIDI clock
messages, or by tapping a foot switch.
Use TEMPO parameter.

0 = Same delay time for L&R.
10 = Slightly differing delay times for L&R,
which produces a stereo type effect.
If the DLYL and DLYR parameters are set to
the same (or similar) delay times, this effect
may sound like a signal phasing problem. If
so, adjust the L/R parameter to correot it.
