SwingThing Posted March 19, 2023 Share Posted March 19, 2023 I built this but I see that the speaker is still active with the headphones attached. I found by adding a 1kOhm resistor from pin 7 to pin 5 tells the detector a wired headset is attached and mutes the internal speaker. Here is a photo showing the solder side of the connector with the headphone and USB connections shown (sorry about my drawing of the headphone jack). 3 Link to comment https://www.detectorprospector.com/topic/11989-simplex-mod/page/2/#findComment-237434 Share on other sites More sharing options...

I never had that problem with my adapter, speaker disconntected when adapter was plugged in. 1 Link to comment https://www.detectorprospector.com/topic/11989-simplex-mod/page/2/#findComment-237834 Share on other sites More sharing options...
dr_maddog Posted March 23, 2023 Share Posted March 23, 2023 Nice mod Sven! I like the new position and secure mounting of the adapter to the detector. I have always found the headphone wire or adapter to be a failure point among multiple headphones or headphones adapter brands.

NilsK Posted October 28, 2024 Share Posted October 28, 2024 Hello DIY detectorists, does anyone know if the pinout is the same on the legend detector? I tried it (without the resistor) on mine and the speaker is still on while no sound comes out of the headphones.. Thanks for any info you might have..
