The Fredenstein F602 is a high-performance tube compressor module designed for the 500 Series format, offering professional recording and mastering engineers a blend of vintage warmth and modern precision. Utilizing the original 6386LGP double triode tube, the F602 delivers the smooth, musical compression characteristic of classic designs like Gates, Fairchild, and GE. Its transformerless input circuit ensures clarity, while the Lundahl output transformer adds desirable character. The module features a short signal path for enhanced smoothness and includes controls for threshold, ratio (2:1 to 20:1), attack (250 µs to 15.5 ms), release (12 ms to 5 s), and make-up gain. Additional features include a mix control for parallel compression, selectable hard or soft knee compression, and a VU meter that toggles between gain reduction and output level. The F602 also offers a true hard bypass and a standby switch to extend tube life when not in use. Its high current design and low output impedance allow it to drive complex loads without sonic impact. Please note that due to its power consumption of approximately 8W, not all 500 Series racks are suitable for this module.
