With the EM-302 RingoLA Circuits introduces a high-quality four-quadrant ring modulator that does more than just sum and differ two signals. The two inputs are level adjustable, which especially benefits sawtooth and square waveforms; however, sine and triangle at the inputs achieve the cleanest results. With bias, the zero-crossing of a waveform can be shifted to the positive or negative range. This makes the EM-302 one of the most flexible of its kind, covering sounds far from metal. Ever ringmodulated an envelope with a sine wave LFO? At the latest with Ringo this leads to really interesting results.
