How would I connect my powered subwoofer to this: https://www.ebay.com/itm/Amplifier-...h=item2ce16e4118:g:PxYAAOSwsn9cFvYl:rk:7:pf:0

My TV has optical out and this appears to have an optical input - right?

Thanks

 

I don't think it does.

 

I'm not sure what are the audio inputs, but I see none that are optical.
You would likely have to also purchase an optical audio to analog output converter.

So here's the type of adapter you need to convert the TV digital audio to an analog signal for the amp.

 

Thanks and you found the lowest price too!

 

MY sound bar has a number of different inputs. The base speaker just plugs into the electrical outlet on the wall. The base speaker connects to the sound bar via (probably) blue-tooth. No need to wire the woofer on my system. You might try yours without going through the expense of getting a cable that might not be needed.

When I power up my sound bar it takes about 5 seconds before the woofer engages. The nice thing about this arrangement is that I can put the woofer elsewhere in the room, not even close to the TV and get magnificent sound.

 

How would I connect my powered subwoofer to this:

That amp is for an unpowered subwoofer.
To connect your powered subwoofer, you could sum the two analog signals from the digital to analog audio converter using a couple resistors, and connect that summed (mono) signal to your subwoofer.
