Bettermaker® Mastering Compressor is for those who seek mastering grade compression with the convenience of fast and precise recall and automation.
Mastering Compressor offers 100% analog signal path, high class VCA compression with, 3 different compression modes, sidechain with HPF, parametric and LPF section with hardware insert and preview function, Stereo/Dual mono/MS operation, adjustable THD saturation and more..
All this with mastering grade sound and patented recall with a speed of a native plugin. 
​

Digital Section
The sound of the Compressor is of course based on the quality of its analog audio path. But all the control and user interactions are performed in the digital domain. This allows us to incorporate options and possibilities not found in any standard analog compressors:

- Save and recall presets from on-board memory (400 slots available)
- Instant reset of all parameters
- Rapid, precise and repeatable adjustments
- Precisely linked stereo operation with the ease of a single control
- DAW automation and recall of all available parameters
 
The digital section of the Mastering 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 Mastering Compressor functions.
 
The use of separate ground planes for analog and digital section results in perfect noise isolation between these two worlds. High quality switching power supply, designed by Bettermaker, was used to provide low hoise, hum free power to all analog and digital components.
​
Front panel and LCD touchscreen
The front panel of the Mastering Compressor is build around big LCD touchscreen, that allows you to control almost all functions available in the device. Apart from that, you can also monitor input/output levels, amount of gain reduction applied by the compressor or store and recall presets using on-screen QWERTY keyboard.
 
The Bettermaker Mastering Compressor can communicate with your DAW via USB connection. The unit appear as a HID device and can be managed via Bettermaker Mastering Compressor Plugin.
