Diode 609

Diode 609 is a diode-bridge compressor plugin modeled after the classic 33609, the British studio workhorse heard on countless records since the 1980s. It delivers smooth, musical compression with a distinctive creamy thickness and harmonic weight, thanks to its feedback circuitry. This makes it ideal for gluing drum buses, adding weight to vocals, or placing an entire mix in front of the speakers. Beyond the vintage character, it offers modern extras: a high-pass filter with a dedicated preview button, a 200ms recovery setting, and a 10:1 ratio for more aggressive control. An independent limiter and extensive controls let you shape tone and dynamics on any source. It suits hobby producers and mix engineers chasing that legendary console sound, and runs natively on Mac or PC, or in real time on Synergy Core hardware.
