FET Compressor
The FREDENSTEIN V.A.S. Compressor is a single channel FET compressor with stereo link capability. It incorporates Fredenstein's unique Reverse-Mancini FET architecture for increased linearity and noise performance. In addition, the output stage consists of our high-performance OPA2 discrete operational amplifier coupled to a high-quality, American-made steel core transformer. Like all Fredenstein products, the OPA2 is not a copy of an old design, but a completely new circuit made with SMT technology. The integrated, matched dual-input transistors ensure significantly improved specifications compared to older models. The OPA2, in the tradition of well-known manufacturers, is encapsulated and can be replaced without tools. The industry-standard pin-out makes it compatible with many manufacturers. To achieve maximum sonic performance, no polarized, electrolytic or tantalum capacitors are used in the signal path.
Overall, the FREDENSTEIN V.A.S. Compressor supports a wide range of different sounds, from smooth and clean to aggressive and destructive. As a truly flexible compressor, it features rotary controls for Input Gain, Attack Time, Release Time, Compression Ratio, Side-Chain Bandwidth (Low-Cut Filter), Make-Up Gain, and Wet/Dry mixing (parallel compression), as well as illuminated switches for Bypass, Stereo link, and Side-Chain filter.
Operating the FREDENSTEIN V.A.S. Compressor is very simple thanks to its separate gain reduction and output level meters. Gain reduction is indicated with 12 LEDs from 1 to 16 dB, and the output level in the range of -30 dB to +20 dB (0 dB = +4 dBu). Other professional features include a hard bypass when switched off and a three-second power-on delay to suppress pops, as well as a remote bypass function in Stereo link mode. Only one bypass switch needs to be engaged to put both units into Bypass mode for easy stereo safety checking, with or without compression.
For easy touring and recording worldwide, the FREDENSTEIN V.A.S. Compressor has a built-in universal power supply ranging from 90Vac to 240Vac, 50-60 Hz.
Like all Fredenstein products, the V.A.S. Comp is designed by a German-American team and manufactured in Taiwan.
