Thanks for your inquiry. To use a 220 volt product on a 110 volt electrical outlet, you would need a step-up transformer. The maximum power consumption of the Companion 5 system is 300 watts and the Wave system is 60 watts. We recommend consulting your local store directly regarding possible availability. Thank you.

Have you tried using the 3.5mm cable port? This would plug into the "line-in" port on the right side of the Companion 5 control pod/volume from the 3.5mm jack on the tv. That would only take a cable long enough to go between the devices. This is also the same cable that you would use to play Apple devices, etc. in addition, you should be able to set the volume level on the Companion 5, and still be able to utilize the volume on the device. Always remember that the light on the Control Pod is: Red: Off, Amber: Muted, tap to change to green, and Green: Go. I include that due to my own frustration at the time of purchase, and realizing that it was a good thing to check... I hope that this information is helpful!

We strongly recommend using the Companion 5 system with a computer via USB. While it cannot connect to a TV by USB, it does also feature an AUX port on the control pod. Connecting a 3.5mm auxiliary cable from the TV’s headphone output into the AUX connection on the control pod will route sound from the TV to the Companion 5 speakers instead.

If you are looking for a similar style system that is intended for use with a TV and other home theater equipment we would suggest you consider our Cinemate GSII,

Thanks!

Best Buy should have either of the 2 cables that you need. If you need the cable that plugs into the bottom of your Apple device for the docking station, those should all be in-store. In addition, if you are in need of the 3.5mm audio cable that plugs into the headphone jack, Best Buy will have those, too. If you only need playback, and not simultaneous charging, you can plug the auxiliary line cable into the right "line-in" port on the Companion 5 control module/volume.

For Bose Companion 5, you might not need sound converter. The USB is for your computer, and there is a control that you could plug in audio in and headphone out. I never try what you suggest but rather connect to my computer via USB.

The Companion 5 is designed to connect directly to a computer via USB. An analog audio device can also be connected via the 3.5mm AUX in jack located on the system’s volume control pod. If you have a device with only an optical out, a DAC could conceivably be used to connect it to that analog AUX in. There is no way to convert an optical signal to work with the USB input on this system.

If you are looking for similar equipment with an optical input for use with home theater equipment, our Cinemate speakers might be a good alternative.

I think the sub might have sound enhance that make the sound a lot better. The USB is connect in to the sub than two cables out to right and left speakers. I never try on my TV before but play music on my computer via USB make the sound a lot better.

The Companion 5 is intended for desktop use with a computer. It can thus only accept high-quality digital input via a connection to a computer via USB. Because this product is not designed for use in a home-theater setup there are no appropriate inputs for that type of equipment. You would find the correct inputs and a much better overall TV listening experience from one of our Cinemate products.
