A:
The BDVE3100 does not have a built in radio. The Home Theater System (HTS) has an digital optical input wherein you can connect your TV so that the sound will be routed to the HTS.
Speaker wires are proprietary on this HTS so speakers that are not supplied with the system would not work. For more information about connection you may refer to the link below.
