I have pair of Sony speakers left over from a surround sound system I've re-purposed. I would like to use the speakers with a Samsung 32" LED smart TV. Can I do this with a pre-amplifier, or will I need to use an amplifier?
External speakers cannot be directly connected to the TV. The TV must be connected to an audio system. Use the HDMI-ARC (Audio Return Channel) feature with a compatible home theater or a sound bar. For a stereo system or receiver without ARC, use an optical cable. If your audio system does not have an optical input, then use an Optical to Stereo converter or connect your external device (Cable box, DVD player, etc.) directly to the audio system.
You will need an amplifier unless the TV has speaker connections (most don't). The analog audio signal coming out of a TV is equivalent to the audio signal that would come out of a pre-amplifier.
