This is a great video synth on its own, but with the accessories I'm selling it with it's much more interesting, plus it can be compatible with LZX analog video synthesizer systems if one of the PCBs for the RGB Output PCB is completed.

Included in this sale:
3TrinsRGB+1c 2015-2016 with Distressed Finish
4 Plugins: SPST&SPDT, P:2xSPD&4xSPST, 2xVideoInNegative, Video in-Lines
2 Reverse Landfill Comparators
3 RGB Output Module PCBs
A whole mess of patch cables

The front panel was a special run by Gieskes that was treated with acid of some kind and then neutralized. So the front panel is mostly grey, but is a bit uneven, intentionally. Kind of like buying new acid washed jeans or "Road Worn" Fender guitar.

I built this unit and used it for years both in my studio, as well as for a small number of visuals performance gigs. It works great and is extremely fun to use. A side note is that it can be used as a drone audio synth, which is honestly mesmerizing to use while also using it to output video, as well as a simple synthesizer voice with the addition of a VCA module.

Here's a page about the plugins that includes a few videos: .

On the patchbay you're connecting an input and an output directly, what the plugins do is allow you to affect those values, patch in other things instead of what's already available, or patch things together in ways that aren't possible using only the internal circuits.

I marked the polarity of the power adapter on the unit, but that can be rubbed off with things like GooGone or other citrus cleaners. The polarity is printed on the unit as well.

GIESKES 3TRINSRGB+1C

3TrinsRGB+1c is an analog video synthesizer that excels at producing glitchy visual patterns and colorizing/keying effects for incoming video. This synth is a perfect standalone option for anyone looking to dive into the world of analog video synthesis and processing.

3Trins provides three internal oscillators, each tied to the Red, Green, and Blue color channels, respectively. The oscillators can be switched individually from vertical to horizontal range, and offer continuously variable sync—providing users direct control of the stability of the generated patterns. Each oscillator has continuously variable frequency and volume, as well as the option of triangle, ramp, and saw waveforms. Dedicated CV inputs for each channel offer even more options for modulation and real-time interaction from modular synthesizers, sequencers, and other external gear.

The device also offers a composite video input, making it easy to use as a bizarre colorizer and image processor. Dedicated brightness, color inversion, and image scrolling controls offer direct impact over the incoming video signal—and of course, said signal can be mingled together with the internal oscillators in a number of ways for even more esoteric effects.

A built-in pin header patchbay enables creation of complex modulation paths, allowing use of internally-generated signals to influence one another. One could use the LFOs to modulate oscillator sync intensity, or could use the video input to modulate oscillator frequency—the possibilities are numerous.

3TrinsRGB+1c is a peculiar and singular device, bringing re-configurable video mayhem to the hands of synthesists, visual artists, and tinkerers alike.
