Versatile and Well-Defined Tube Mic Pre Built in a 500-Series Format
$689.00
The F609 is a professional tube microphone preamplifier, using two double-triodes, one ECC802S (12AU7) and one ECC803S (12AX7), in a single 500 series rack module. It provides an +160V power-supply to avoid starving the tubes. The F609 uses high quality American made input and output transformers.
The main feature of the F609 is the combination of the Input Gain knob (0 to +70 dB) plus Output Gain Knob, plus all-tube signal path. The output level control allows to change the characteristic of the amp and to run the first stages all the way up to distortion and it is genuine old-school tube distortion. The sound is very smooth with a big, well defined low-end. This little module can rock with the best of them.
The F609 is particulary interesting paired with the F602 tube compressor, if you happen to like high end vintage flavors and genuine tube character. It also pairs nicely with the Artistic Compressor and Artistic Leveller for traditional 70's style tube mic-pre into solid state FET or Opto compressor chains. Some engineers chain all three.
Additional features are: 20db Pad, polarity control, phantom power, a two stage low-cut filter, and a standby mode to preserve the tubes if not in use. The traditional VU meter is standard.
Not all racks can supply the 250 mA that the F609 requires, but any of the Bento series are well suited to provide that.
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.
