The Retro 2A3 Dual Channel Tube Program Equalizer is a high-fidelity tool designed to deliver natural, musical equalisation with the signature character of classic passive EQ designs.
Featuring vintage tube amplification and custom transformers, the Retro 2A3 captures the essence of industry-standard Pultec EQs while offering enhanced high-frequency boost options and newly implemented tonal refinements.
True passive EQ circuitry, free from amplifier feedback, ensures smooth, organic curves even at extreme settings. With dual channels housed in a compact 2U unit, the Retro 2A3 is ideal for stereo applications, individual tracks, or cascaded EQ processing.
The Retro 2A3 also includes a new subsonic filter with selectable 40 Hz and 90 Hz peaking settings, adding punch and clarity without sacrificing low-end detail. From subtle tonal shaping to bold mix buss enhancement, the Retro 2A3 delivers a rich, flexible sonic palette for modern studios.
