I need some clarity AKA HELP lol I want to add a cheap china wireless headphones to my TGSL It has two channels A and B I want to use a Toggle Switch DPDT On-Off-On like this one https://www.ebay.ca/itm/10pcs-Mini-T...item210e8602ef Top half will be for channel A and b which is straight forward and bottom half will be to give the 3 volts to the little circuit, here the question, I have a speaker in my case which I want to leave in there but I would like to have it turn off if I flick the switch to either channels, all using the same DPDT, when its at the off ( middle) the speaker will be on, and when on1 or on2 is switched I want the speaker off, Anyone have an idea how I would wire it or do I need to add a sort of of diode or something component to the switch ???

I think is good idea to have wireless headphones, but switch must wired correctly. On possible solution is to use 3pdt switch. Along with LEDs to show either a or b state.( A/B switch circuit. KT solution to switch in a resistor across speaker terminals would effectively mute the speaker when the switch is thrown. Good idea as well.Originally posted by Tibuck19 View Post

If I understand you correctly, the circuit needs 3 volts p.s. then when you throw switch to one side, the other side goes open, so if you want to turn on 3volts as well as redirect signal to a and b channels, then you need to join a and b on one terminal and 3 volts to other terminal on same side of switch. On other side of switch you have speaker out. Middle of switch you have 3 volts on one side and audio output signal from pcb.
So when switch is in middle position everything off, when switch is left, headphones, when switch is right, speaker.Comment

that's right up too "when switch is left, headphones, when switch is right, speaker" the on1 or on2 on 3 terminals will simply to switch from Channel A Or Channel B that are different FM frequency middle will be off for the power going to the circuit of the wireless, by using the 3 other poles of the switch , when its powered down I would like to use the speaker.Originally posted by dbanner View PostComment

this job doing not by the switch. this job doing SOCKET like in every detector you see them there as a standart.

Now I see that wireless has 2 separate channels for different frequencies. Where you are going to put wireless device? Is it going to be inside box. What about interference issues.Comment

My preference would be to plug in the wireless to headphone jack, with the right Jack, the power supply for the wireless can be from detector circuit.Comment

Can you put link for the wireless device you are thinking of using?Comment

Most people seem to go with Bluetooth, but I never tried. There is a lot of mods discussion on another forum about people who do this mod. Here is just one such thread.

Also I see it talked about elsewhere about low latency of device. The delay between target and when you hear response in headphones. I think one would need a low latency device. This is issue if using digital wireless device.Comment

Yes right inside the box so far while testing there doesn't seem to be any issue with the wireless being close to the board no odd humming and no sensitivity lost , I wish I could link the product, I was something I picked up at a goodwell store besides being a cheap china product I have no clue where its from lol I don't have a volume knob on the TGSL but the wireless headphones have them built in .Originally posted by dbanner View PostComment

For wireless inside box, All you need is nice switch for headphones/ speaker. Your switch will be ideal. Then a second SW for A/B freq. The first switch can be appropriately wired for putting 3 volts on wireless when switch is thrown to headphoneOriginally posted by Tibuck19 View PostComment

Yup that switch is find for both flipping to either channels, as well as a power on and off to the Wireless, my idea was to find a simple way besides adding a second toggle switch to have the speaker turning off when wireless is on . what I think KT was getting at, by adding a 1K resister, was to basically shorting out the speaker when the little board is active, Perhaps maybe ???Originally posted by dbanner View PostComment
