Manufacturer's Description from Fredenstein

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.

About Manufacturer

Think about what is sonically missing in today's audio equipment and how you could achieve better results in recording and mastering? Now, many go back to well proven classic pieces of audio gear to fight the shortcomings of digital recording. Could that be the ultimate solution? Did the improvements in technology during the last 50 years really don't apply to recording? Using technologies from vacuum tubes to Digital Signal Processors, often in the same product, Fredenstein products combine the strength of each technology and avoiding their weaknesses. In addition we strongly believe in Zero-Negative-Feedback, negative feedback is a technique to make amplifiers more linear, but at the same time making them sounding harsh. This is one of the reasons modern equipment sounds so similar. Omitting negative feedback and using an internally and externally balanced designs which are very linear by design will yield a natural sound on a different level, warm, not dull or muffled, instead with a rich silky top-end and an impulse response will simply blow you away. Don't get us wrong, we are not talking about 「esoteric designs」, we believe very strongly in a scientific engineering approach.

 

We also provide pieces of long neglected equipment like precision analog meters. Even if you are working mostly inside the 「box」, metering your analog signal before it hits your converters is still very important and a great foundation for good recording. Fredenstein's state-of-the-art audio technology will help you throughout your chain to achieve truly outstanding results.

In addition, Fredenstein believes recording engineers deserve to have a more user friendly, more convenient and efficient pieces of equipment making the studio life easier and generate a more comfortable working environment. By minimizing the number of buttons and switches without sacrificing the functionality we deploy a clean user interface allowing you to get instantaneously familiar with the products.

Fredenstein Professional Audio Products are designed for audio professional in recording and broadcast studios as well as independent engineers and producers in their own facilities.

Fredenstein is focused to make a difference in Professional Audio. You can expect superior sound and high-end built quality from each of our products
