Manufacturer's Description from Fredenstein

The Artistic Leveler - Opto Compressor

 

The Artistic Leveler is a single channel opto compressor with multi-channel link capability in the 500 series form factor. If used in Fredenstein Bento 6 or Bento 10 racks, an external side-chain input is available through the Aux input connector.

The Leveler features rotary controls for Input Gain, Release Time, Compression Ratio, Make-up Gain and Wet-Dry Mixing (parallel compression). The Attack Time can be set in three steps, as well as the side-chain low cut filter., the side-chain can be fed externally by activating the LED bar-graph meter indicates the gain reduction in the range of 1dB to 16dB. It's punchy and detailed sound is generated by three major components:

1) Fredenstein's proprietary Reverse-Mancini opto architecture

2) our advanced OPA2 discrete Audio Operational Amplifier

3) the American made vintage style steel core output transformer

 

Like most opto compressors, the Fredenstein Artistic Leveler features a fixed threshold. The compression depth is controlled by changing the input gain. Increasing the input gain will cause the Leveler to apply an increased gain reduction. The output level control is used to make up for the gain reduction. The maximum compressor output gain is +20 dB.

The ATTACK TIME switch and RELEASE TIME control define how fast the compressor reacts and how fast it falls back after the signal is lower than the threshold. The perfect values are depending on the program material and the desired sound..

The COMP RATIO control sets the relationship between input and output level for signals above the threshold and can be varied from 2:1 to 7.5:1. 

Additionally, so-called dry/wet mixes can be performed (parallel compression). The dry signal (uncompressed) and the wet signal (compressed) can be mixed together in any relationship to achieve special sounds. The Wet-Dry control of the Artistic Leveler dramatically boosts the versatility of the device. If you put the Wet-Dry control fully counter clockwise, only the compressed signal is present at the output, if turned fully clockwise only the unprocessed input signal reaches the output. Another sound shaping tool is the three position side-chain low cut filter. If switched to 150 or 300Hz, it prevents low frequency signals below the selected value from being processed by the compressor. If the external side-chain input is used, the dynamics of the signal can be controlled by another source, which allows for more creative sounds.

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
