## Description

DEVICE CONTROLS Threshold Control and LED This is probably the most important control on the Comp Pro. It is adjusted to determine when the compressor is working or when sound is being passed through unaffected. The Threshold control is turned down or CCW until the THRESHOLD LED turns Red as you play your instrument. When the THRESHOLD LED turns Red the Comp Pro is actively compressing your signal. If the LED is Green, the Comp Pro is not compressing and sound is passed through unchanged. Range of Adjustment is from -50dBu to +10dBu. 2.45mVRMS to 2.45VRMS Pro Audio (studio) Levels are +4dBu Consumer Audio Levels are -10dBu. Passive guitar or bass pickups are typically about -25dBu to 2.5dBu. Ratio Control Ratio is the amount of compression you set the Comp Pro for. You can set it from No Compression (1:1) when all of the way off or CCW. You can set it as high as Infinite Compression (:1) which means that the output level will never increase in output level no matter how loud the input. This type of setting can be used for hard-limiting to protect recording or speakers or in some cases for guitar effects like chicken-pickin. Attack Control Attack Times between 0.15ms and 150ms. Controls the time it takes for the Comp Pro to start compressing. RELEASE Control Release Times between 0.1s to 3s. Controls the time before the Comp Pro releases or stops compression . Gain Control This is the output level of the compressor. It does not affect the compression controls like THRESHOLD, RATIO, ATTACK or RELEASE. It is for make-up gain if you set for heavy compression gain reduction. +20dB of boost is possible. Knee Switch Hard Knee Compression follows a hard fast rule: If THRESHOLD is met, then Compress at this RATIO. Soft Knee is Komfort Kompression. Its a way to keep compressed guitar or instrument parts sounding lively and dynamic, without the blanket of compression found in many types of compressors.
