i've got a question for someone electrically or electronically literate - i have a basic "fred flintstone" literacy from working on cars years ago
i'm connecting this "stereo" laptop speaker set to a hikvision outdoor camera, images below
the green plug on the camera only has two connection slots for audio marked "GND" and "A" for audio, per the manual. The other two are for alarm, ie PIR, I/O, so i assume it's only meant to generate Mono output, which is understandable.
below is the volume control switch between the USB 2.0 plug & 3.5mm male jack and the speakers
on the right side of the switch, are the R & L speaker connections (top right you can see R+ & R-, and you can barely see the L+ & L- at the bottom right
on the left side there's a black & red pair of leads that are coming from the USB connector which i assume are the power leads. Also on the left side of the switch are a green lead, yellow lead and white lead which come from the 3.5mm male jack. I've assumed the green lead is the GND lead and the other two are L & R
here's the question. When i connect the speakers to my computer, i get a small windows menu opening that allows me to test the speakers, L and R separately, and when i test them i get sound only from the appropriate speaker, ie L or R
But when i connect only one of the L or R leads, i get sound out of BOTH speakers, it doesn't matter whether i connect the yellow or white to the camera. I've also connected both the yellow and white to the "A" port on the camera's connector, same result which i would expect
how can i be getting that result, ie sound from both speakers with only one side connected. I was hoping to disconnect ie cut, one speaker out to better fit the laptop speaker inside the old nutone intercom box at the entrance way, but when i do, i loose all sound??? BTW, that laptop speaker set splits into two separate speaker housings
any help appreciated
