Mounting PJ-3001F / PJ-301M / PJ-366ST Sockets on a Eurorack Control Deck

N8 Eurorack Control Decks provide a Jack-Pot-Switch (JPS ) cell matrix. Each JPS cell allows you to mount various components to meet your Eurorack module’s requirements. The layout of the components is matched to our pre-drilled Eurorack panels.

Each JPS cell on an N8 Eurorack Control Deck can accommodate either a 9mm Alpha RD901F-40 style pot, RV09AF-40 style trimmer, 3.5mm PJ-301M style jack, sub-miniature toggle switch or LED.

PJ-3001F,  PJ-301M-12 ( aka  Thonkiconn ) style vertical 3.5mm jack sockets are soldered to the N8 Eurorack Control Deck using the vertical “ABC” pads. As these pads can also be used to mount a sub-miniature SPDT switch, make sure to align the jack correctly, as described below.

The long shield pin of the PJ-3001F socket should connect to the lower of the two “C” pads. The switch pin to the “B” pad, and the tip pin in the upper hole of the “A” pad. Stereo sockets like the PJ-366ST use the same pads, with the “B” pad becoming the ring connection.

The three connections appear at the Control Deck’s edge connector, as indicated on the rear of the board. An N8 Eurorack Control Deck connection reference can also be found here.

N8 pre-drilled Eurorack Panels have 7mm diameter holes to accept a range of components in each position. We recommend using a washer and hex nut to fix 3.5mm jacks to the panel. All our 3.5mm jacks ship with a nut and washer.

For perfect alignment, position sockets and other components on your N8 Eurorack Control Deck and affix the panel using the nuts and washers before soldering.

Check that the jacks are square to the Control Deck and centred in the panel, and adjust as needed before soldering into position.
