Page 3: Overview
Overview Thank you very much for purchasing/consider to purchase Gotharman’s EuroBoard MkII. EuroBoard is a eurorack module which can hold one of the analog filter boards, which are available for Little deformer 3, Tiny LD, Urano, Anamono X and Xmini, for using these filters in a eurorack system. -
Page 4: Parameters
Parameters The four main parameters are Cutoff, Cutoff2, Reso and Feed. These parameters might have different functions on the various filters. This will be explained for each filter board in the following chapters of this manual. The Cutoff parameter can be modulated by the CutCV1 and CutCV2 inputs through the attenuators. - Page 5 The Feed parameter can be modulated by the FeedCV input through the attenuator. The LPF, BPF and HPF switches are used for switching specific filter outputs on or off, and for changing filter modes. The functionality of these are explained separately for each filter board in the following chapters.

Page 6: Jumpers
VCF menu. On EuroBoard MkII you will have to set the polarity of each parameter, using jumpers. The recommended jumper settings are shown for each filter board in the following chapters of this manual. - Page 7 The Reso and Cutoff2 jumpers. When a jumper is placed on the upper 2 pins, the parameter is normal. When a jumper is placed on the lower 2 pins, the parameter is inverted.

Page 8: Installing A Filter Board
Check the chapter in this manual, for the filter board that you will install, and set the jumpers to the recommended settings. Place the filter board with the electronic parts facing upwards, into the filter board connector. Insert and tighten the vinyl screw that came with EuroBoard MkII, into the filter board hole, using a screwdriver. -
Page 9: Connecting The Power
Connecting the Power Connect the power cable with the brown cable (-12V) facing upwards, if it is a multi-colored cable, or the red line facing upwards, if it is a grey cable. Connect the other end of the cable to your eurorack power bus. -
