COMPOSER PRO
Interactive 2-channel expander/gate/compressor/limiter of the reference class
sIKA (Interactive Knee Adaptation) compressor concept combines the advantages of “hard knee” and
“soft knee” characteristics
sAttackandReleasetimescontrollableautomaticallyormanually
sSwitchable high-pass filter in control signal path avoids low-frequency signals from dominating compres-
sor action
sCompression characteristics switchable between IKA and “hard knee” characteristics
sIRC circuit in expander/gate allows for “inaudible” elimination of disturbing noise signals
sIGC (Interactive Gain Control) peak limiter combines clipper with program limiter circuits
sExtremelylow-noiseoperational amplifiers and high-grade VCA’s
sHigh-qualitydetentpotentiometersandbacklitswitches
sStereoCouplefunction selectable with real totaling of RMS output
sAccurate 12-digit LED meters for input level, output level and gain reduction
sTraffic-light function for easy threshold setting
sSwitchable side-chain input with side-chain monitor function
sOperating level switchable from +4 dBu to -10 dBV
sServo-balanced inputs and outputs featuring 1/4" jack and XLR connectors
sHigh-gradeoutputtransformerBEHRINGEROT-1 can be retrofitted
sRelay-controlled hard-bypass switch with auto-bypass function (fail-safe relay)
