[QUOTE="mbasko, post: 556384, member: 4485"] [img]https://www.prospectingaustralia.com/forum/img/member-images/4485/1590546027_screenshot_20200527-121735_adobe_acrobat.jpg[/img] The GPX battery has an inbuilt amplifier. When a correctly wired (as above) speaker is used it will detect it from the wiring & automatically increases the audio level. The battery can automatically detect (sleeve connected or not) if headphones or a speaker is in use (depending on wiring) & adjust the audio level to suit. Headphones are wired TRS (tip, ring & sleeve). Speakers that will be or might be used plugged directly into the battery should be wired TR (tip & ring) only to switch on boosted audio. [/QUOTE]
