It has been designed to work as a studio compressoraccepting any range of inputs and a frequency response and noise levelmatching the finest compressors made. General Compressor Usage The Keeley Compressor Pro is designed to be used at home or in thestudio for creating full sounding recordings of any instrument. In live situations, the Compressor Pro can be used to achieve fullsounding, polished performances as well as protect amplifiers andspeakers from overload.

Device Controls THRESHOLD, RATIO, ATTACK, RELEASE, GAIN, KNEE, & AUTO THRESHOLD Control and LED This is probably the most important controlon the Comp Pro. It is adjusted to determine when the compressoris working or when sound is being passed through unaffected. TheThreshold control is turned down or CCW until the THRESHOLD LED turnsRed as you play your instrument. When the THRESHOLD LED turns Redthe Comp Pro is actively compressing your signal. If the LED isGreen, the Comp Pro is not compressing and sound is passed throughunchanged. Range of Adjustment is from -50dBu to +10dBu. 2.45mVRMS to2.45VRMS Pro Audio (studio) Levels are +4dBu Consumer Audio Levelsare -10dBu. Passive guitar or bass pickups are typically about-25dBu to 2.5dBu. RATIO Control the Compression Knob, Ratio is the amount ofcompression you set the Comp Pro for. You can set it from NoCompression (1:1) when all of the way off or CCW. You can set itas high as Infinite Compression (:1) which means that the output levelwill never increase in output level no matter how loud the input. This type of setting can be used for hard-limiting to protect recordingor speakers or in some cases for guitar effects like chicken-pickin. ATTACK Control Attack Times between 0.15ms and 150ms. Controlsthe time it takes for the Comp Pro to start compressing. RELEASE Control Release Times between 0.1s to 3s. Controls thetime before the Comp Pro releases or stops compression. GAIN Control This is the output level of the compressor. Itdoes not affect the compression controls like THRESHOLD, RATIO, ATTACKor RELEASE. It is for make-up gain if you set for heavycompression gain reduction. +20dB of boost is possible. KNEE Switch Hard Knee/Soft Knee. Hard Knee Compression followsa hard fast rule: If THRESHOLD is met, then Compress at thisRATIO. Soft Knee is Komfort Kompression. Its a way to keepcompressed guitar or instrument parts sounding lively and dynamic, without the blanket of compression found in many types of compressors. AUTO Switch OFF/ON Set to ON in most cases for automatic setting ofAttack and Release Times. This will sound natural and work in avery large number of cases. The Comp Pro looks at the inputsignals like guitar, bass, vocals or drums and determines the correctattack and release times depending on what youre playing and whatsignal levels are being detected. Good Compression Settings SMOOTHING Changes in signal level happen when the singer moves awayfrom the microphone or when a guitar player may not use perfecttechnique in controlling their dynamics, i. Less than perfect pickinghand technique. To smooth changes in dynamics use the Comp Profor low to medium compression. Set AUTO Switch to ON. Adjust the Compression RATIO Control to 2:1 to 4:1 for example. Set the Gain Reduction LEDS by adjusting the THRESHOLD Control toindicate 3-9 dB of gain reduction on the 7 Segment LED Bar. Adjust GAIN Control if needed. Set KNEE Switch to SOFT. Nowplay slow and steady chord work, list to how toggling the KNEE switchback and forth Hard/Soft affects your tone and the attack or punch ofthe notes as well as the release. SUSTAIN To add sustain to guitars or keyboards start with a higherCompression RATIO setting for example 10:1 to :1, Set THRESHOLDControl so that THRESHOLD LED turns Red for average level of yourguitar or performance, the LED stays red about half the time. Youcan set the KNEE Switch to HARD or SOFT, SOFT may seem more transparent. CHICKEN PICKING COMPRESSION Set RATIO Control to 5:1 to 10:1, a quickRELEASE Time of. ATTACK Time for quick attack 10-50ms andTHRESHOLD Control set to give you 9-12dB of Gain Reduction/Compressionon the 7-Segment COMPRESSION LED Array. This will typically giveyou compression artifacts or effects like a breathing or pumping sound. BASS BOOM AND SLAP For a punchy bass guitar sound set the Comp Profor a medium to high Compression RATIO (6:1 to 10:1) and adjust theTHRESHOLD so that the -12dB and sometimes -20dB COMPRESSION LEDs arelit while playing. Set KNEE to Hard mode. That will makethe bass punchy and slap a bit harder, reducing boominess. TrySoft KNEE for a a different feel. PREVENT DIGITAL DISTORTION Set Keeley Compressor Pro as a HardLimiter by turning RATIO control all of the way up to Infinity to Onecompression ratio. Set KNEE for Hard.
