From vinyl mastering to digital,

The Bernie Grundman Mastering team believes in providing the highest quality mastering possible in the LA music industry! In order to give you the best, we use only the best of everything! Our disc mastering console was hand built by our technical engineers. Its design is the same as our other consoles, but with the addition of preview signal paths. The console can be fed from our custom made solid state or tube tape electronics, computer, cd, dat etc.. In turn, the console output can be fed to either tube or solid state cutters for disc mastering, or to analog tape, high resolution computer files, or other digital medium for archival purposes. All analog tape and digital playback equipment is program/preview capable.

The mastering systems have been modified numerous times to incorporate new ideas. This helps our mastering engineers achieve their goals. However, in the end, the ultimate goal is to give our clients a superior product.
