- The 4020 Retro EQ is a four-band EQ and complimentary filter set. The HF and LF bands are shelving EQ, with two additional parametric EQs at the HMF and LMF bands.
- The 4030 Retro Compressor is a new dynamic range control topology coupled with a wet/dry mix control to balance compressed and uncompressed signals. An active attack and release design allows aggressive compression settings with minimal artifact generation.
- The 4040 Retro Limiter combines a look-ahead brick wall limiter function with several subjective treatments to make the limiting action subtle, and yet vintage.
