The MULTIFLANGE flanger delay clock chip includes an LFO with seven waveforms, including a ?manual? mode for fixed flanger (?matrix?) filtering effects. LFO Rate, Waveform, and Depth are all variable using 0-5V control voltages. The chip outputs a biphase clock from 25KHz to 500KHz that can drive MN32xx-series delay lines directly.
DIP 8 enclosure.
