■Controls:
・THRESHOLD and LED: This control determines the compression behavior. The LED is red when compression is in progress, and green when the original signal is output unaffected.

・RATIO: This control sets the compression ratio. Turning it fully counterclockwise results in no compression (1:1). Turning it clockwise increases the compression ratio. At ∞:1, the output remains constant, regardless of the input signal.

・ATTACK: The attack time can be set from 0.15ms to 150ms. This adjusts the response time to the input signal before compression begins.

・RELEASE: The release time can be set from 0.1 seconds to 3 seconds. This controls the time it takes for the compression to end and the signal to return to its original volume.

・GAIN: This control adjusts the output level and does not affect compression settings such as THRESHOLD and RATIO. This is used as make-up gain for heavily compressed signals, and can provide up to +20dB of boost.

・KNEE Switch: Hard Knee is a clear control method that instantly compresses at a set ratio the moment the threshold is exceeded. In contrast, Soft Knee has a more gradual, natural compression characteristic, achieving smooth compression while preserving the instrument's expressiveness and dynamics.

・AUTO Switch: The OFF/ON switch is a function that enables automatic setting of the attack time and release time. Normally set to ON, Comp Pro automatically adjusts the optimal timing according to the signal from guitar, bass, vocals, drums, etc., achieving natural compression.

■Power Supply: 9VDC center negative
