The 4020 Retro EQ is a four-band EQ and complimentary filter set. The HF and LF bands are shelving EQs, with two additional parametric EQs at the HMF and LMF bands. All EQ bands operate on a unique gain dependent variable slope/Q system for a vintage smooth sound and increased boost/cut frequency selectivity high gains. The HPF and LPF filters use a unique split-octave design giving a 12 dB/Oct slope near the selected frequency, and a maximum slope of 24 dB/Oct.
All Retro plug-ins use a McDSP designed output stage that puts a unique transformer-like touch on the audio signal. This feature is in addition to the analog saturation modeling that has made McDSP famous over the last decade. Retro plug-ins are a line of ‘classics’ that can live up to their own name without emulating something else.

Crisp Drums
The smooth sound of the 4020 Retro EQ shelving EQs can beef up the low end and liven up the high end.
Big Bass
Signal boosts from the LF band used in conjunction with cuts from the LMF band give a good ‘meaty’ sound to many low end tracks.
Clean Vocals
The 4020 Retro EQ gentle curves can give a vocal track that ‘polish’ it may need to cut through the mix.
