Used only a few times. Power-on confirmed. - Model: Emerald Compressor - Brand: floatia Designs - Controls: Compress, Output The following is a description from floatia Designs: - - - - - - - - - - - - - - - - - The Emerald Compressor is a simple compressor for guitar/bass. It's a direct descendant of the highly acclaimed and sold-out Risa Compressor, combining simple, intuitive operation with high-quality sound. Traditional parameters such as attack and release are preset to optimized values, so you won't get lost even if you don't have specialized knowledge of compressors. The main feature is that you can intuitively set it up by simply determining the compression threshold with the left knob and adjusting the output level with the right knob. The compression circuit uses an optical type with a classic CdS photocoupler. Generally, optical types are said to have soft and natural compression curves, but this unit uses selected photocouplers with a fast release time, and the response is very fast, handling even hard playing without any problems. Also, when Compress is at 0, it becomes a complete buffer amplifier, and the input signal is output almost unprocessed. It can also be used as a booster in a state where compression is not applied. As an optional function, you can change the gain of the output amplifier with the internal trimmer. By increasing the gain, you can add saturation-like distortion. Please try the "compressor that didn't exist but should have" produced by Floatia Designs. Size: 122 x 67 x 40mm (excluding protrusions) Power: DC9-18V operation (center negative), battery operation not possible *This unit consumes a lot of current. Please use a power supply with a low impedance output that can sufficiently secure a current of 100mA or more. Insufficient current may cause noise. - - - - - - - - - - - - - - - - -
