Description
Bettermaker Mastering Limiter 2.0 is a 2U rackmount stereo mastering limiter combining a 100% analog signal path with digital control via a front-panel touchscreen and a DAW plugin over USB. The 2.0 revision adds an improved limiting engine, redesigned clipper and color/saturation section with mid-side matrix, sidechain high-pass filter and mid boost, plus a new GUI and wide-angle high-contrast screen. The analog section handles up to +24 dBu balanced input and +27 dBu balanced output through low-noise op-amps and relays with true bypass, while two microcontrollers manage limiting, presets, metering and USB. Metering covers input/output/gain reduction plus VU/PPM/RMS/peak, LUFS, K-metering, a 30-band FFT analyzer, goniometer and correlation meter. Retailer listings cite a 2U enclosure 230 mm deep with approximately 5 kg shipping weight; the manufacturer page did not expose an MPN or GTIN.
