Fuse Audio Labs has released VCL-373, a recreation of an early 1960s broadcasting limiter/compressor that eventually found its way into many mastering studios. In 1963, the famous diode-bridge based gain reduction stage was replaced by a transistor-based circuit that allowed for less THD and more reliable control voltage tracking. VCL-373 includes a faithful emulation of the audio transformers, the crucial feedback compression circuitry, as well as the discrete class A make-up amplifier. Some convenient features have been added to the digital version, including a continuous drive control, gain compensation, GR metering, and a dry/wet mix.
Fuse Audio Labs VCL-373 is available now for $59, with an introductory price of $29 until July 15. It requires macOS 10.8 or later and an AU, VST, or AAX plugin host.
