INTRODUCTION
ThankyouforchoosingCompIQMINIProCompressorasyouraudio
dynamicprocessingtoolforyourinstrument.
CIQ‐2 CompIQ MINI is an all analog studio grade compressor
featuring Ratio, Threshold, Make‐up Gain manual controls,
Soft/Hard Compression Knee selector, Auto Adaptive Attack &
Releasetimingswhichrespondtoplayingdynamics,andDry/Wet
Mixcontrolforaperfectblendofprocessedandcleansignal.Atrue
RMS‐level detector constantly measures input signal and applies
accurate compression through a transparent sounding, high
performance Blackmer® VCA. The exact amount of compression is
indicatedbya5‐LEDdisplay.
EFFECTCONTROLS
FOOTSWITCH ‐ When engaged, the switch routes the audio signal
throughthecircuitryandPowerLEDislitGreen.Whenpushedagain,
thesignalisroutedinTrueBypassfromInputtoOutput,leavingthe
audio untouched. This routing is still available even when pedal is
notpowered.
RATIO‐Thiscontrol sets howmuchtheaudiosignalisgoingto be
compressed, after it passes above the set threshold. It has a
continuousrangestartingfrom1:1(foroneunitofinputsignallevel

2:1 ratio ‐ a mild, musical and very useful compression, which

whennotesustainisneeded,oracountrystylemusicisplayed.After
20dB amount of compression, the amplitude reduction tends to
behavelikeInf:1 ratio,whichcorrespondstoLimitingeffect. When
used as limiter, use Threshold control to set the level after which
compressorwillactlikealimiter,andsetRatioabove10:1.Keepin
mindthatthemorecompressionisapplied,themoremake‐upgain
isneeded,whichresultsinanormalincreaseofnoise.
THRESHOLD ‐ This control sets the signal level after which
compressionisapplied.Compressionisonlyappliedtotheportion
ofsignalthatgoesabovethethreshold.Setverylow,itmakesthe
compression kick in immediately even for small input signals. Set
higher,itletsagoodportionofthesignaluntouched.Thisisavery
powerfulcontrol,becauseitallowsthecompressiontoaffectonly
higherstrokesofsignal,whileleaving the meat and bone of audio
untouched. This also translates into a greater sound transparency
and an increase in output level, making some make‐up gain (or
mixingDry/Wetsignals)totallyunnecessary,which,inturn,reduces
amplification noise at the output. Because of the 50dB threshold
range,CompIQcanaccommodateawiderangeofaudiosignalsfrom
electric instruments. With an appropriate preamp, it may be used
evenwithvocal orinstrumentmicrophones. WhenThresholdisset
higher,CompIQcanbeusedwithstudiolinelevelsignal.
MAKE‐UPGAIN ‐ Because compression meanslowering theoutput
signal,somerecoverygainisneeded,tomatchoutputwithinput
level.The more compressionisapplied(highercompressionratio),
the more recovery gain has to be dialed in to compensate.Be
awareofthefactthatathighercompressionratios,therecovery
circuitmustre‐amplifyaverylo
wsignalandwithamplification,more
noise is introduced. To overcome this, we strongly advise using
Threshold, setting lower compression Ratios. Ultimately, blend in
somedrysignalwiththeMixcontrol.However,itmakesnosenseto
over compress a signal at low thresholds just to recover its gain
afterward,andincreaseoutputnoiseresultedfromamplification.
DRY/WETMIX‐Thiscontrolactslikeanaudiomixer,whereyoucan
blend input clean signal with the output compressed signal. This
helps restore some transients or some squished frequencies which
arelessperceivedby ear,becausetheyare reducedtolowerlevel,
aftercompression.Whenthetrimmerissetinthemiddle,themixis
50‐50. Such a setting washes out a lot of compression feel, and

feeling. The dry signal is a perfect replication of the input signal.

SOFT/HARDCOMPRESSION KNEE‐Rarelyavailableincompression
pedals, this control multiplies the compression flavors that can be
achieved. The Hard Knee compression is evident and the ear will
perceive the dynamic processing easily. Once signal gets above
