Some TV facts: Televisons come in many makes and models, ALL the connections I will describe are optional
Audio OUT (left/right RCA (Phono) jacks)
Headset
Digital audio out (RCA jack)
Optical audio out (TOS/Link transmitter,, TOS is short for Toshiba by the way, pronounced Toss, and "toss" the audio it does, no handshaking).
Also some TV's have video out and assorted inputs, which do not apply to this discussion.
Likewise some Radios have a LINE-IN or AUX-IN jacks, this may be a 1/8 Inch stereo headphone type connector (Only it's an input) or a pair of RCA jacks
Some may have digital or optical (RCA or TOS/link receiver)
The Tos-Link receiver and transmitter are balck, with a square tipped dust cover and a "D" shaped hole, the transmitter has an LED in it and glows red.
IF you have matching outputs on the TV and inputs on the radio.. USE THEM.
Else, the Headset jack may be able to power line in (Aux) on the radio if it has it using the proper adapter cord (Radio shack still sells those).
Or the speakers.
Problem with powering the speakers.
In my coach the speakers are high power, designed to handle 70 watts per channel, the TV, puts out 5-10 if I'm lucky, Not nearly enough power. But with it's own speakers, lots of power.
Home was where I park it. but alas the.
