AJH Synth Mega-Phase 12 is an effects module for modular synthesizers in Eurorack format. The module is based on the Electro-Harmonix Small Stone Phase Shifter guitar effect pedal circuit. In contrast to the effect pedal, however, the number of filter poles has been increased to 12 and can be selected by means of an eight-step rotary switch. Independent of this, the number of filter poles in the feedback path can also be selected using a rotary switch. Mega-Phase 12 has two audio inputs, two adjustable CV inputs for the filter frequency (1x unipolar, 1x bipolar), and one input each for Emphasis and Dry/Wet Mix. The built-in LFO can also be used for other tasks and is normalized to the first input for the filter frequency. At the end, a stereo output signal is available on two mono mini jack sockets.
