R-FIER STACK
This is modeled on the MESA/Boogie Rectifier. This
super high gain amp is capable of producing slash metal,
grunge, and a wide range of other lead sounds.
ACOUSTIC SIM
By combining acoustic guitar simulation with COSM
amplifier modeling technology, this original amplifier
model gives you a dynamic acoustic guitar sound using
a standard electric guitar.
MIC
Select this position when microphone is connected.
* Howling could be produced depending on the location of
microphones relative to speakers. This can be remedied by:
1. Changing the orientation of the microphone(s).
2. Relocating microphone(s) at a greater distance from speakers.
3. Lowering volume levels.
* All product names mentioned in this document are trademarks
or registered trademarks of their respective owners, and are not
related to Roland Corporation. In this manual, these names are
used as appropriate ways to indicate sounds that are simulated
using COSM technology.
10.GAIN Knob
Adjusts distortion level.
11.VOLUME Knob
Adjusts channel volume.
EQUALIZER
12.BASS Knob
Adjusts the tone quality of the lower range.
13.MIDDLE Knob
Adjusts the tone quality of the midrange.
14.TREBLE Knob
Adjusts the tone quality of the upper range.
* Because COSM faithfully models the special features and
characteristics of a variety of amplifiers; no sound will be
produced when BASS, MIDDLE, and TREBLE knob are all
set to 0 while the Type switch is set to BLACK PANEL.
EFX (Effects)
15.EFX (Effects) Knob
Turn this knob to chorus, flanger, phaser, or tremolo to select
the corresponding effect. Turn the knob to adjust the amount of
effect applied. You can also turn EFX on and off using optional
footswitches (BOSS FS-5U or FS-6).
* Graduations for CHORUS, FLANGER, PHASER, TREMOLO
on a panel are for reference. Be sure to check the sound as you
adjust the effects.
CHORUS
This is a spacially synthesized
chorus. With spacially synthesized
chorus, a method available only in
stereo, the chorus effect is created
by taking the sound from the right
speaker (from which the effect sound is output), and the
sound from the left speaker (which outputs the direct
sound), and then mixing them in the actual space. This
creates a greater lateral spread than that produced when
the sounds are mixed electronically, providing a more
natural sense of breadth.
FLANGER
This creates a flanging effect that
creates a sort of spinning sensation
with the sound.
PHASER
This effect adds a variable
phaseshifted signal to the direct
sound, giving the sound a swirling
character.
TREMOLO
Tremolo is an effect that creates
a cyclic change in volume.
DELAY/REVERB
16.DELAY/REVERB Knob
Turn this knob to DELAY or REVERB to switch to that
effect.Turn the knob to adjust the amount of effect applied.
DELAY
Turn the knob to change the time and
amount of delay effects.
REVERB
Spacious-sounding stereo reverb is
provided. Turn the knob to adjust the
reverb level.
17. Power Indicator
This indicator lights when the unit is turned on.
* When operating on battery power only, the unit's indicator
will become dim during play when battery power gets too low.
* Sounds may distort easily or may cut off when played at high
volume as the battery power begins to fade, but this is normal
and does not indicate a malfunction. In such instances, either
replace the batteries or use the AC adaptor included with the
unit.
