Product introduction
 
CP540V2 is a one channel microphone signal compressor and limiter. Both the compression and limiter electronics circuits are completely independent and can be used separately or together via the illuminated buttons that corresponds to each side. It is not only compression input signal but also limit the output level. When its output level reaches a specific number, its limited circuit will keep the same output level. Compression combines with limited function solve the distortion in a way. Its diversity knob in front panel enhances performance speed.
 
Feature
 
Mic compressor combines mic limiter
The circuit adopts high quality component ensures low distortion and purity sound quality
Its shell adopts dust-free spraying processing makes product concise and better adhere
The chassis is made from high quality steel to provide extra shielding against stray magnetic and RF
High pass filter let high frequency pas and cut some low frequency
Features THRESHOD, RATIO, ATTACK, RELEASE knobs to get and outstanding sound qulity
