Prism Circuits

Prism Circuits set out to create an easier way of building these vintage instruments, and to put them in the hands of the people who love to build, create, and inspire. Our goal is to make the build experience a smooth and effortless process by using quality PCB's to offer a high-end product that can stand the test of time. We love these magnificent instruments that were once dubbed the people's synthesizer.

Programmer Stage, 1973 Oscillator, Gate, 1973 Filter and Envelope Generator are among Prism Circuits most popular products.

News from the Labs

Prism Circuits
5 Dec 2023 Prism Circuits
All Prism Circuits modules are now available in the Loudest Warning format! This format allows the user to custom design a system module by module, making the process less expensive to start and get your foot in the door within the Serge Modular ecosystem. You can find the Loudest Warning product line here - https://prismcircuits.net/collections/lw-panels/Loudest-Warning 
Prism Circuits Low-Pass Gate
7 Nov 2023 Prism Circuits
The classic Low-Pass Gate will be available in Serge format! This module will add some much needed tambres to the already incredible Serge sound palette. Module will be released in built system, Loudest Warning modules and as a DIY project. Module will be released in late November.  
Prism Circuits Utility Mixer
8 Jul 2022 Prism Circuits
Prism Circuits has released a new small single column Utility Mixer for audio and DC signals. The UTILITY MIXER is a DC coupled audio processor that can be use with audio signal and CV signals. There are 2 attenuverting inputs for deep CV processing and one unity gain input that sums to the mix output. This module can be used as an audio mixer or CV processor.  
Prism Circuits Spring Reverb
3 Apr 2022 Prism Circuits
The Serge Modular Spring Reverb has been released and is up for sale in DIY. www.prismcircuits.net 
Prism Circuits Random Voltage Generator
25 Jan 2022 Prism Circuits
Prism Circuits has just released the long awaited Random Voltage Generator! The RANDOM VOLTAGE GENERATOR produces random voltages which vary smoothly or in a stepped manner. Random timing pulses are also available. Rate of change of all outputs is voltage controllable over a wide temporal range. Noise is built into this unit and can be broken out onto its own jacks as an optional Noise Source.  
Prism Circuits VC Phaser
26 Oct 2021 Prism Circuits
The VC PHASER has also been released and available at www.prismcircuits.net. This rare Serge Module is back in DIY and a part of our Pre-Built Panel collection.
