"This little case is only 2.83″ x 2.08″ x .93″ and it will fit in your pocket. This ring mod is now the perfect size to slide it in your instrument case, and take it along to a show or band practice. The input is on the right, the carrier is in the center, and output is on the left. Decals for the case are coming soon!"
"Two input signals are multiplied together and the resulting output is the sum and difference of the frequencies of each. The germanium diode ring provides the effect with a minimum of signal distortion while the transformers segregate your audio sources for the internal circuitry. The circuit requires no external power supply!Measuring 2 9/16″ x 1 3/16″, the Passive Ring Modulator PCB is a compact, high quality circuit board manufactured by Imagineering out of Elk Grove Village, IL. The layout is a custom design by our resident electronics engineer, Steven S. The PCB allows for the transformers and diodes to be soldered directly to the board neatly and a ground plane helps reduce interference from external noise and RF."
Looks like a simple bridge rectifier to me.
ReplyDeleteTake a closer look: The diodes are pointing in different directions than if it was a standard bridge rectifier. This is a classical ring modulator with two transformers and four diodes coupled in a ring - hence the name. I have build one myself and it actually works.
