PREFACE

First of all, congratulations on t e purc ase of t is 3U Eurorack synt esizer

module. T is manual contains a condensed description of t e functionality

and addresses users wit a certain level of elementary tec nical knowledge.

T e CS-8 COOK is a more persuasive VCA mono compressor wit softknee

c aracteristic and adjustable Side C ain input. It is based on t e known "ebbe

und flut" arc itecture, w ere only one knob controls t e T res old, Make-up

Gain and Ratio at t e same time. It is designed for mounting into a 3U Eurorack

wit an internal +/- 12V power supply.

Compared to t e "ebbe und flut" t e time constant (Attack/Release) is now

continuously adjustable over a wide range and moreover anot er peculiarity is

added one not meet in ordinary compressor designs, t e parameter

"Response". T is generates an overs ooting, adjustable in 4 steps ( eig t of

overs oot), of t e RMS-converter in case of dynamic c anges of t e input

signal. By adjusting t e time constant wit t e r yt mic timing very strong

pumping and compression effects are possible. Furt ermore t is compressor

is perfectly suitable as a bass-compressor down to lowest sub-frequencies.

Definitely a fun maker wit a superior dynamic range!

Design and implementation meet ig est tec nical standards concerning

usability, sound quality, and signal-to-noise ratio. T e front panel is made from

powdered and printed piece of aluminium s eet metal of 2 mm gauge. T e

entire design and production work was done in Germany.

Made in Germany
