Limited Edition Pittsburgh Modules Starting with the Dual Ring

via Pittsburgh Modular

"We are starting a line of limited edition modules as a way to share some of our more esoteric designs with the world. The modules will range from chaotic and noisy, to simple, to over the top. Each production run will be limited to 50 modules, and each module will be hand signed and numbered on the rear of the panel. All limited edition modules will be available for sale exclusively on shop.pittsburghmodular.com, and once they are gone, they are gone.

We are pleased to announce the Dual Ring, our first limited edition module. The Dual Ring houses a pair of ring modulators with linked inputs and an output mixer, creating unique sonic and signal routing possibilities. The Dual Ring was a request of our good friend Dave Skipper. We were a little skeptical at first but the results prove this was an inspired idea."




[The Dual Ring houses a pair of ring modulators with linked inputs and an output mixer creating unique sonic and signal routing possibilities. Each ring modulator offers 3 types of effects based around the classic ring modulation circuit.

A ring modulator multiplies two audio inputs together resulting in a unique form of amplitude modulation or frequency mixing. The output is the sum and difference of the frequencies present in each waveform. Ring modulation produces a signal rich in harmonic and non-harmonic tones often sounding metallic or bell-like.

The individual ring modulation circuits in the Dual Ring can be used independently, mixed, or chained together resulting in a large palate of uniquely rich and complex tones.

Effect 1: Ring Modulator - (Switch Full Left) Outputs the sum and difference of the X and Y inputs.

Effect 2: Floating Z Modulator - (Switch in Center Position) Outputs the sum and difference of the X and Y inputs summed with the ambient voltage within the circuit.

Effect 3: Linear Amplitude Modulator - (Switch Full Right) Outputs the sum and difference of the X and Y inputs summed with the carrier (Y) signal."

via Pittsburgh Modular on what it's like to be a boutique modular manufacturer and why they decided to come out with the limited edition modules:

"Three years ago Pittsburgh Modular Synthesizers started as a crazy idea to sell a few strange, handmade modules out of a basement. Thanks to your enormous response to those modules we've grown meteorically.

Shipping modules and instruments in large numbers takes a tremendous amount of time and resources. Resources that we can not commit to every idea we have. While we have been working hard to expand and improve our manufacturing capabilities, at heart Pittsburgh Modular is still a small company that remains committed to producing high quality, hand made electronic instruments. Over the past few years, we have chosen to focus our energy on modules that make up the core of our amazing synthesizers. Because of this, we have a lot of concepts and a lot of modules that were designed but never sold. Most of our ideas are too strange to fit in with what Pittsburgh Modular has become and it would be impossible for us to maintain a product line that included all of our designs. Still, we want the modules for our systems so here is the idea..."
