In the upper position of the corresponding switch the inverted signal is used. In the center position the input in question is turned off (mute) and in the lower position the \"normal\" (i.e. non-inverted) signal is used. The inverting of signals is used especially for control voltage signals (e.g. LFO, ADSR). But even for corellated audio signals this feature is useful. For example for feedback applications or the mixing of original and processed signals (e.g. original and filtered signal to obtain new filter types).\u003cbr data-mce-fragment=\"1\"\u003eChannel 1 features in addition an Offset function: provided that no plug is inserted into socket Input 1 control Lev.1 generates an adjustable DC voltage (positive or negative depending upon the position of the polarity switch).\u003cbr data-mce-fragment=\"1\"\u003eOn top of that the module is equipped with two types of single outputs and a dual mix output. \u003c\/span\u003e\u003cspan size=\"2\" face=\"Arial\" data-mce-fragment=\"1\"\u003e All inputs and outputs are DC coupled. Consequently the VCAs can be used to mix both audio and control voltages.\u003cbr data-mce-fragment=\"1\"\u003eEach input is  - apart from the polarity\/mute switch - equipped with a linear attenuator. The amplification range is 0....1.\u003cbr data-mce-fragment=\"1\"\u003eThe single outputs offer the attenuated and possibly inverted\/muted signal of the channel in question.
