This studio-quality compressor specializes in soft compression that does not impair the nuances of the performance, and is compatible with a wide range of compression methods from soft to hard. Compared to the regular Focus, it has flatter characteristics from low to high frequencies, making it ideal for those who prefer a natural sound or for instruments such as electric acoustic guitars that do not require a boost in the mid-range. There are five knobs: compression, level, gain, treble, and bass. It eliminates concepts like threshold, ratio, attack time, and release time, allowing you to intuitively create sounds in three steps: compression setting, level adjustment, and tone correction. It is equipped with an LED that displays the amount of compression, and you can intuitively understand the compression status by the timing when the LED lights up, the intensity of the light, and the timing when it goes out. The level and gain knobs are located after the compression stage, allowing you to choose whether to boost (return) the volume that would otherwise be reduced by compression with the level knob, or to boost (return) it with a warm, tube-like sound with the gain knob.You can also set the desired balance. The treble and bass are flat at the 12 o'clock position, and by adjusting the treble and bass, you can change and adjust the character of the compressed sound to your liking. The volume can also be boosted using the level and gain knobs, so it can also be used as a booster.Connection terminals: Input, Output, DC9V In Accessories: instruction manual, warranty card Input impedance: 2MΩ Output impedance: 10kΩ or less Current consumption: 26.5mA
