I have a BC2 and BV8-40 in main room and want to move an Avant to a link room which presently has a BL Wireless connection to main room and BL4000 speakers connected to it. 

Can I connect the BL4000's to the Avant and the Avant via Masterlink to the Receiving Wireless unit? I will connect the TV to an RF outlet in this link room. 

Will this setup allow me to hear music from main room in the link room? The TV should operate as usual.

Many thanks
