Manufacturer's Description from Fredenstein

The Fredenstein F676 Microphone Preamplifier is a valve (tube) based preamp with a fully balanced signal path throughout. It features transformers on the input and output. The F676 uses a DSP to control the operating points of the tubes, guaranteeing perfect working conditions all the time.

 

The final result is a tube preamp with a very pleasant sonic footprint, lush smooth highs without being harsh plus very detailed mids and lows. The physical footprint is also very well suited for many desk-top situations where it can be conveniently put within arm's reach.

 

Control functions include 0 to 76 dB of gain in 1 dB steps along with a 20 dB pad. It also includes the usual Phantom Power, Polarity and High Pass Filter switching and 2 impedance settings (1K ohms and 200 ohms). The F676 has a few unusual controls; one for setting Fully Balanced or Single Ended circuitry and another that injects DC into the output transformer. Each is intended for creating desirable vintage characteristics beyond what the basic tube / transformer topology does. The F676 also allows for saving and recalling 99 User Presets.

 

The LCD graphically displays Peak output level and Gain settings. It also displays tube currents while it self-calibrates so that you can be confident that the unit is working optimally.

 

The name F676 is an homage on the famous German V76 tube microphone amplifier which was the sonic inspiration for this unit. The F676 will make a positive difference in your studio.

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
