Bettermaker[reg] Bus Compressor is for those who seek high quality stereo VCA compression with the convenience of fast and precise recall and automation. The bus compressor offers 100% analog signal path, Dry/Wet mix, sidechain with HPF, with hardware insert and preview function, adjustable THD saturation and more. All this with high analog quality and patented recall with a speed of a native plugin.

The digital section of the Bus Compressor is based around high speed, 32-bit micro-controller, with dedicated firmware programmed into its memory (with the possibility of updating the firmware via USB connection). It's responsible for controlling the VCA, the user interface, presets management, audio measurement, USB connectivity and other Bus Compressor functions.

The use of separate ground planes for the analog and digital sections results in perfect noise isolation between these two worlds. The Bus Compressor's high quality switching power supply, designed by Bettermaker, provides low hoise, hum free power to all analog and digital components.

The front panel of the Bus Compressor is build around an eye-catching LED matrix display, that allows you to monitor almost all functions available on the device as well as input/output levels and amount of gain reduction applied by the compressor.
