Dumb Q -- non-powered speakers connected to TV-out
I just bought a pair of JBL Control1X speakers. They have traditional
connecting posts (two wires, one to each post). My tv-out jacks are RCA plugs. I took a pair of RCA-RCA plugs and cut each one of the pair; separated the signal and ground, and plugged the signal into the + post, and the ground into the - post of the speakers. However, no sound comes out. Somone on a Web forum had told me this setup would work ... but of course they could be wrong. Do I need to have an amp between the tv-out and the speakers? Or should the speakers work the way I did it, and perhaps something else is wrong? I formerly had some powered computer speakers plugged in to the tv-out jacks, and they work fine. If I need an amp, what's a good one to get? This isn't a mega home theater setup, I just want to put a pair of speakers on my tv. Thanks, I hope this question's not too dumb. |

Do I need to have an amp between the tv-out and the speakers? Of course. The RCA outputs are not amplified and the speakers require amplified signals. I formerly had some powered computer speakers plugged in to the tv-out jacks, and they work fine. That's because they have amps in them. If I need an amp, what's a good one to get? This isn't a mega home theater setup, I just want to put a pair of speakers on my tv. Google for T-Amps. Used to have them at Target. Kal |

Dumb Q -- non-powered speakers connected to TV-out
I have a 1987 Mitsubishi TV that still works like new that has a built in
amp to power external speakers. But few tv's have that feature. "fishfry" wrote in message ... I just bought a pair of JBL Control1X speakers.

Dumb Q -- non-powered speakers connected to TV-out
General Rule of Thumb: RCA plug = line level output. Binding Post =
speaker level output. TV's rarely have speaker level outputs. Exception to the Rule: Bose is so cheesy, they use RCA plugs for some their speakers (and about 24 gauge wire).

Yes, you need a power amplifier betweeen the TV audio outs and the speakers.
The audio-out RCA jacks on your TV are pre-amp output jacks. They put out a tiny signal for an amplifier to boost to drive the speakers. -- --------------------- DaveW --------------------- "fishfry" wrote in message ...
