Synthrotek
Passive Ring Modulator KIT
The
Synthrotek
Passive Ring Modulator
is the classic 2 transformer – 4 diode ring modulator circuit in a
conveniently small package. Passive ring modulation is a bizarre and
otherworldly sound effect appearing in such diverse places as sci-fi
robot voices, trippy psychedelic guitar solos, metallic analog synth
samples, and more! There’s nothing on this planet that sounds like
ring modulation and now you can get it for cheap! Experiment with all
of your gear and you’ll definitely come up with some surprising tones
you never knew you had access to.
Operation:
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!
The three jacks are Carrier Wave 1, Carrier Wave 2, and Output. Plug two different signals into Carrier Waves 1 & 2 and listen to the sound flow. You can actually use any two jacks as inputs and the third as the output; each combination gives you a different sound.
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.
The kit comes with 1/4″ jacks.
*** The
Synthrotek Passive Ring Modulator Kit
includes all
of the
components you’ll need to build your very own Ring Modulator
except the case

The build is a great beginner’s 1st project with a big payoff!
Kit Assembly Instructions
Bill of Materials
Note: the Passive Ring Modulator needs a hot signal in order to get an effect. Guitar signals and some line level signals will need to be boosted.
