Both units offer linear or exponential frequency shift in a range of +/- 5kHz and are capable of thru-zero operation. You can control input level, the amount of frequency shift and the feedback. The last two parameters can be voltage controlled with voltages in a range of +/-5V.
Due to the dual layout it is well possible to process left and right channels of a stereo signal separately to create 3D-like effects. Putting the frequency shifters in series might produce very unique results as well.
This high-quality module works with 16Bit and 48kHz and has a frequency range of 20Hz-20kHz.
Each channel has one audio input, one audio output, one frequency shift CV input and one feedback CV input
