Extron Captive Screw to 3.5mm Jack Audio Adapter

Adapter for Extron Captive Screw to 3.5mm stereo jack (for unbalanced audio).

Features

• Small, compact size.
• Easily connect 3.5mm stereo audio cable to your switcher's audio input/output.
• Protects against connecting (unbalanced) output GND to the wrong minus (-) pins (which can damage your equipment!).
• Snug fit.

Bill of Materials

• 3.5mm Stereo Female Jack with Screw (model PJ-399M 3-pin)
• 2.54mm Dupont Female Connectors (1-pin) + 26-28AWG flexible wire 
• OR already crimped 2.54mm female Dupont wire

Instructions

• Print @ 0.1mm layer height WITH initial layer also @ 0.1mm.
• Clean after printing to remove residual material/strings which can affect the snug fit.
• Keep wiring short (3-4cms).
• The Dupont female connectors will snug-fit in place but you can add a small drop of super-glue to permanently bond them to the adapter, especially if you are going to plug/unplug the adapter frequently.

Disclaimer

1. I'm obviously not responible if you damage your equipment by using this adapter.
