Reverse Landfill Pentamix - DIY Build
Reverse Landfill’s unique approach to modular synthesis is something that they are becoming known for. Their cryptic silkscreens on their panels also makes for some interesting patching if one is unfamiliar with the modules. The Pentamix is one of Martijn’s newer modules that helps bring all of the other Reverse Landfill modules together.
A 5-channel audio mixer, the Pentamix’s real magic happens when you patch the inverted output and use the another output to send out to an effect and then back again into the Pentamix.
With its 555 pentagram, this mixer brings a new dimension to ones rack… but enough about the module, let’s get onto the build…
Resistors and Diodes...
Start with the resistors on this build. There are not very many of them (12 to be exact) and their polarity doesn’t matter. Each resistor set is marked so its easy to figure out what goes where if you can read a BOM. You can find all of the Pentamix’s documentation on the Reverse Landfill website for quick reference.
Diodes are next and one thing we love about Martijn’s modules is the extra power protection. The diodes (x2) will protect your module if the power is reversed for any reason. The 2x resistors next to the diodes are there for extra protection. One thing to know about diodes is that their polarity does matter. You want to be sure that the black line on the diode lines up with the silkscreen on the PCB. A quick tack down of these and its time to move onto the IC sockets and caps.
