Fredenstein Artistic Compressor

The Artistic Compressor is a single channel FET compressor with multi-channel link capability in the 500 series form factor. The compressor features rotary controls for Input Gain, Release Time, Compression Ratio, Make-up Gain and Wct-Dry Mixing (parallel compression). The Attack Time can be set in three steps, as well as the side-chain low cut filter. 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 FET architecture 2) our advanced OPA2 discrete Audio Operational Amplifier 3) the American made vintage style steel core output transformer As all Fredenstein products, the Artistic Comp is designed by a German-American team and manufactured in Taiwan.

Installation:

Please power down your rack or box first, before inserting the Artistic Compressor. Since the Artistic Comp uses the link interconnect in the box or rack, it cannot coexist with any other third-party modules using the same link interconnect (PIN 6 on the edge connector). If you are using a Fredenstein Bento box, please turn off the compressor link switches to any third party module(s), only turn on the link switches between Artistic Comp modules. Other third party equipment not using the link interconnect, such as most Mic-Pres and EQs etc, can be used simultaneously with the Artistic Comp in any enclosure. The power requirements are very light at maximum of +/-16V, +/-75mA and should not overload any enclosure.

Fredenstein Artistic Compressor

Detailed Descripti on:

Like most FET compressors and caused by limitations of FET devices, the Fredenstein Artistic Compressor features a fixed threshold. The compression depth is controlled by changing the input gain. Increasing the input gain will cause the compressor to apply an increased gain reduction. The compressor 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 20:1. A ratio of 20:1 is considered a limiter. Additionally, so called dry/wet mixes can be performed (parallel compression). The dry signal (uncompressed) and the wet signal (compressed) can be mix together in any relationship to achieve special sounds. The Wet-Dry control of the Artistic Comp 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.
