My understanding is that it's all inputs, audio and video.

Umm... see my very first post above. I was commenting on the Telos speaker caps

If your speaker has bi-wire posts but you're single wiring, you must have the jumper link to get both high and low frequencies.

The link can only be removed if you use bi-wire speaker cables. Low quality jumpers can affect the sound quality, you can replace them if you got extra budget.

The jumpers should already provided with the speakers. But if you wanna replace higher quality ones, can buy online at Russ Andrews, FutureShop, etc. I think local shops also got.

Use speaker cable as jumper better than that metal thingy. Ask A&L give u free
