Yes! The ButtKicker Gamer comes with splitter cables that enable you to send an analogue audio output from your AV unit (sub out preferred) to the Gamer amplifier. If no audio output is available directly from your surround system, you can take the audio from the TV.

Normally, USB headphones do not work alongside the Gamer - until recently there was no option within the Windows PC software to send audio to both USB and analogue outputs simultaneously - just one or the other.

Thankfully, there is now a small program called "Virtual Audio Cable" that can be downloaded to fix this problem - so you can use your USB headphones and ButtKicker at the same time!
