The F600A Compressor is a high performance tool for professional recording and mastering engineers. The F600A features a fully externally and internally balanced signal path with much lower distortion than conventional compressors. It comprises of a analog gain control circuit and a digital side-chain based on two DSPs. This technology can achieve more than 20 dB of gain reduction while maintaining very low distortion. Up to ten units can be linked together to form a true multi-channel compressor. The engineer can easily change the compression characteristics by tuning threshold level, attack and release times as well as selecting RMS or PEAK signal inputs to the side-chain. An additional tunable high pass filter preserves low frequencies. Since this high pass filter can be tuned up to 4 kHz, the F600A can be used as De-Esser, or on a lathe, as a cutting speed limiter. The extreme low output impedance with its high current design allows even the most difficult and complex loads to be driven without sonic impact.
