The module only requires regulated +12V and -12V voltages.
6 DEVICE OVERVIEW 5.2 6 Signal Connection The second step is to integrate the cmp1 to your Eurorack system. Device Overview A Compressor Module for the Eurorack world? Really? Ok, as an outboard gear in a recording studio and maybe as a pedal for guitar, but for a modular? Yes, true! Waldorf made it. The fantastic cmp1 compressor module. It’s unusual, but it makes sense and it’s worth to be added to your permanent module environment.
6.4 6.2 Attack and Release 6 Signal Detection 6.4 DEVICE OVERVIEW Attack and Release The level detection could be set via the switch into one of three modes. In the left and middle positions an averaging approach will used called RMS (root mean square). The RMS modes are producing a smooth level detection. The left position (Adapt) will use an adaptive circuit and the middle position a static averaging factor. Just try both modes and let your ears decide.
6 DEVICE OVERVIEW 6.5 6.7 Level Input apply the second channel to the side chain input of the first module and put the Balance knob to 50/50 position. By this the stereo mix is used for level detection and not just a single channel. Hint: Please make sure that the compression knob of the second module is fully closed. The gain, bleed and level knobs are still functional and could be used for additional control.
9 7 Tips & Tricks 9 • Use a loop or other rythmnic source and connect the RMS/Peak output with a filter or gate input. The detector signal works like an envelope follower. • Connect a steady tone to the Main input and feed a drumloop for example to the Side input. Now the steady tone should be modulated by the rhythmic source depending on your Balance level. 8 Troubleshooting 8.1 SPECIFICATIONS Specifications Power Supply: +12V/110mA, -12V/100mA Width: 20HP, 101.6mm Height: 3U, 133.
