Compression, Clean Boost/Gain Boost, and Mid-Range Sound Adjustment It is a completely new concept pedal with intuitive control of all this. Five knobs include compression, level, gain, color1, and color2. The compression function follows the focus of Limetone Audios compressor pedal for studio equipment quality compression with simple operation. When the LED is on, the intensity of the light and when it turns off, you can intuitively know the state of the compression. Level and gain knobs are positioned at the back of compression, allowing for a clean boost by level and gain boost by gain. Especially for gain boosts, the tone curve setting is perfect for pushing subsequent pedal/amplifier distortion, allowing you to create impressive drive sound. Both color1 and color2 are a mid-range control knob, and are flat at 12 oclock. By boosting and cutting a limited range that cannot be operated by an amplifier or normal effector, you can create and drive sound that has never been set before. Also, the FOCUS-NX features one of these color1 and 2 to be turned over at 15 oclock, to create a mid-range sound. Color1 is slightly higher and color2 is slightly lower frequencies, so when you raise color1 to the maximum size, you will get a modern sound, and when you raise color2 to give you a classic half-stopping wow. (It is expected to only raise either side, but you can raise both to create more aggressive sound. Each function (compressor, booster, and midtone shifter) can be used or not used with the knob setting and can be used individually or together. ■Specifications Connection terminal: Input, Output, DC9V In Accessories: Instruction manual (English language not guaranteed) External dimensions: Width & (W) 119 mm, Depth (D) 98 mm, Height (H) 62 mm Weight: 354 g Input Impedance: 1 MΩ Output Impedance: 10 kΩ Current consumption: 26.5 mA *The image is a sample
