The 4TTEN from WMD is an attenuator for four signals that requires just 4HP of space. The module is suitable for all applications where audio and/or CV signals should not be at full power. Due to its active design, the module also works as an offset generator if no cable is plugged into the corresponding input. In this case, an adjustable fixed voltage in the range of 0-5 volts is generated on the channel. The board of the 4TTEN is 113mm high and can be a little tight in some Eurorack cases.
