The F602 Compressor is a true variable transconductance (often falsely called â?variable muâ) high performance tool for professional recording and mastering engineers. The F602 features the original remote cutoff double triode tube used in many vintage designs (Gates, Fairchild, and GE to name a few) called 6386LGP. The signal path is very short and delivers the smoothness you would expect from a great piece of vintage equipment. The innovative transformer-less input circuit yields clarity while the Lundahl output transformer adds character. The extreme low output impedance with its high current design allows even the most difficult and complex loads to be driven without sonic impact. A wet (compressed) and try (uncompressed) mixer further enhances the flexibility of the F602 Tube Compressor. In addition a true hard bypass, which also works, if the unit is powered down, was implemented as well as a standby switch allowing to shutdown the tube circuitry if the F602 is not in use while the rack is still powered, therefore extending the tube life cycle.
