COSM Comp/Limiter
 
(COSM Compressor/Limiter)
 
This effect can be used to produce a long sustain sound by 
evening out volume levels in the input signal. In addition, 
you can also use it as a limiter to suppress only peaks in the 
volume and prevent distortion.
A limiter is an effect that prevents distortion by suppressing 
input signals in excess of a specific value (i.e., the threshold). 
You can also get the same effect achieved with a compressor 
by setting the threshold to a low value.
The BR-1600CD uses COSM technology to model four types 
of compressor/limiter effects, which combine the functions 
of a compressor and a limiter. 
 
Effect On/Off
OFF, ON
 
Sets the compressor/limiter to ON or OFF.
 
Type
 
Selects the compressor/limiter type.
 
Attack
0–100
 
(Active when BOSSCmp or D-Comp is selected.) 
This parameter adjusts the strength of the picking attack produced 
when the strings are played. Larger values will result in a sharper 
attack, creating a more clearly defined sound.
 
Sustain
0–100
 
(When set to BOSSCmp, D-Comp)
Boosts low-level signals, adjusting the time over which sounds are 
sustained. Higher values deepen the effect, resulting in a longer 
sustain.
 
Threshold
0–100
 
(Active when Rack160 is selected.)
Adjust this parameter to match the input signal from your bass. 
Compression will be applied to input levels in excess of this level. 
The smaller the value set here, the lower the level at which the 
limiter kicks in.
 
Input
0–100
 
(Active when VtgRack is selected.)
This parameter controls the input level. Increasing the value will 
produce a deeper effect.
 
Ratio
(Rack160) 1:1–20:1, inf:1 (VtgRack) 4:1–20:1
 
(When set to Rack160, VtgRack)
This adjusts the limiter compression ratio. Higher ratios produce a 
stronger compression effect.
 
Attack Time
0–100
 
(Active when VtgRack is selected.)
This parameter adjusts the amount of time it takes for the 
compression ratio set by “Ratio” to be reached once the input level 
exceeds the set threshold level and compression begins. The larger 
the value set here, the more rapidly compression will be applied.
 
Release Time
0–100
 
(Active when VtgRack is selected.)
This adjusts the time it takes for compression to be removed once the 
signal level drops below the threshold. Higher values cause the 
compression to be released more rapidly, making it easier to 
distinguish the sound from successively played strings.
 
Tone
-50–+50
 
(Active when BOSSCmp is selected.)
This parameter adjusts the tone. Higher values cause the high 
frequencies to be boosted more, and this results in a harder sound.
 
Level
0–100
 
Adjusts the overall volume of the effect.
 
COSM Overdrive/Distortion
 
This effect distorts the sound to create long sustain
 
Effect On/Off
OFF, ON
 
Turns the Overdrive/Distortion effect on or off.
 
Type
 
Selects the type of distortion.
 
Drive
0–100
 
Adjusts the depth of distortion.
 
Bass
-50–+50
 
Adjusts the tone for the low frequency range.
 
BOSSCmp
 
Models the BOSS CS-3 compact effects 
processor.
 
D-Comp
 
Models the MXR dyna comp.
 
Rack160
 
Models the dbx 160x.
 
VtgRack
 
Models the UREI 1178.
 
BLUES OD
 
This is a crunch sound of the BOSS BD-
2.
 
TURBO OD
 
This is the high-gain overdrive sound of 
the BOSS OD-2.
 
BOOSTER
 
This is a booster that works very well 
with COSM amps.
 
DISTORT
 
This gives a basic, traditional distortion 
sound.
 
AMERCAN
 
This models a Proco RAT.
 
GUV DS
 
This models an Marshall GUV’ NOR.
 
OD-1
 
This is the sound of the BOSS OD-1.
 
TSCREAM
 
This models an Ibanez TS-808.
 
DST+
 
This models an MXR DISTORTION+.
 
60S FUZ
 
This models a FUZZFACE.
 
OCT FUZ
 
This models an ACETONE FUZZ.
 
MUF FUZ
 
This models an Electro-Harmonix Big 
Muff 
 
π
 
.
 
MT-2
 
This is the sound of the BOSS MT-2.
 
R-MAN
 
This models a ROCKMAN.
 
HVY MTL
 
This creates a heavier distortion sound.
