Redoptor 2: Vintage Tube Distortion Plugin by D16 Group Free Download

Redoptor 2 models the behavior of a tube amplifier driven into breakup. According to D16 Group, the plugin emulates the tube and its coupled circuits, and its adjustable tube bias parameter adds subtle amplification of even harmonics and gentle transient reshaping.

The preamp cutoff points for high and low frequencies can be set before the signal is amplified and distorted, which gives control over the tonal range from lo-fi to full-spectrum. Each channel of the stereo signal runs on its own path, so the two sides can carry different harmonics and distortion.

The signal chain includes a preliminary filter section, a preamp with a built-in compressor, a fully equipped parametric equalizer with independent gain and frequency control across four bands, and an output limiter. The compressor sits before the distortion stage, and the limiter handles peaks as the signal leaves the plugin.

Redoptor 2 supports 64-bit internal processing, a tag-based preset browser, two alternative GUI sizes and MIDI-learn across its controls.
