A:Answer why would you. I believe you are asking if a transmitter can be hooked up to a transmitter?
Soundbars transmits from audio sources, like TV's, DVD/Blu-Ray player's, Blue Tooth devises etc.etc..
The soundbar has inputs not outputs. The only output on this soundbar is the Sub-Woofer Out.
Use your outputs from you TV to your Headphone transmitter.
This unit has Blue Tooth, which will receive a BT signal from any compatible devise.
I hope that helps..
