Mastering Compressor

Following the renowned Mastering Limiter and Mastering Equalizer, Bettermaker has expanded the line with the Mastering Compressor.  As with all Bettermaker hardware you get the best of both worlds:  the signal path is 100% analog with top quality components and parameters are controlled digitally via front panel touchscreen/controls or remotely with a free DAW plug-in.


Multiple compression flavors

The Mastering Compressor features an advanced analog VCA compressor with stereo, dual-mono and M/S operation modes, complete with solo and sidechain preview functions.  It also includes 3 unique compression modes: BM (Bettermaker), SG (SSL-type), and DX (DBX-type).  The BM mode offers the most gentle but very versatile compression that works for the widest range of settings.  The SG and DX modes offer compression types in line with the classics they have been inspired by.



Versatile control

The Mastering Compressor is loaded with options including stereo, dual-mono, and M/S modes for all types of mixing and mastering applications.  It also includes a dry/wet control for parallel compression and the sidechain features a HPF, LPF, and fully configurable parametric filter with the option of using a hardware insert.  For those looking to add some flavor to the signal, the Mastering Compressor can also add color with adjustable drive and THD function to add harmonic saturation.  The range setting limits the max amount of gain reduction.  If you are tracking a vocalist and want compression but don’t want to overdo it, you can set the range to limit the amount of compression.  All your settings can also be saved and recalled on-board or within your DAW.  Fire up your session and pick up right where you left off!
