Bus Compressor

– advanced analog stereo VCA compressor with PEAK detection
– all parameters are digitally controlled via front panel and/or DAW (with dedicated plugin)
– dry/wet MIX control for parallel compression
– sidechain high pass filter with hardware insert and preview function
– adjustable THD for harmonically rich sound
– on-board measurement of PEAK/RMS levels
– 100% analog audio signal path
– total recall and A/B comparison from your favourite DAW
– LED matrix display and six encoders with push-button action for ease of control
– USB connectivity with MAC/PC

Digital Section

The digital section of the Bus Compressor is based around two high speed, 32- bit micro-controllers, with dedicated firmware programmed into their memory (with the possibility of updating the firmware via USB connection). One of them is responsible for controlling the VCA compressor, when the other watches over the user interface, presets management, audio measurement, USB connectivity and other Bus Compressor functions.

The use of separate ground planes for analog and digital section results in perfect noise isolation between these two worlds. The linear power supply was used instead the switching one to improve the sonic qualities even further.
