Synthrotek Quadrangle - DIY Build
The Synthrotek Quadrangle is a quad cascading triggered envelope generator with bipolar output attenuversion and is 20HP module with a lot of versatility. With 4 cascading envelope generators and user voltage control over attacks and decay/release, this module is in a class all to itself.
As the fall season slowly began creeping in, we decided to go back and see what kits we had left to build for the year. To our surprise, we totally forgot that we had the mysterious Quadrangle from Synthrotek up on our build wall. This was partially due to the studio remodel and the continuous go go go of daily life.
When we opened up the kit, the first thing we noticed was the size of the boards. This was a BIG module. 20HP to be exact. It consisted of 2 PCBs and one panel. We ordered the kit with the black panel but Synthrotek also offers a silver panel. As this kit was a big one, we knew we where in good hands with the amount of build data there would be available.
Included in the kit was a printed BOM as well as all the components you need to complete the kit.
Intermediate to advanced builders will not have an issue with this build, whereas novice builders could struggle due to tight soldering pads.
