How to connect LED TV to external speaker

Hi guys. I am not a techie so pardon me for my lapses.

I have an LG LED TV and I bought a Sonic Gear Armageddon a5 speaker.

I tried to connect it to the headphone jack of my LED TV but I am only getting a very weak volume on my Sonic Gear speakers. I need to max the volume to 100 so I can get a decent sound out of my speakers.

What should I do? Do I need to buy a special cable? Someone told me that I need a receiver?

A bit confused here now.

Thanks for your help.

some tv has line out rca port, labelled as 'monitor'. some tv has the same port for audio both in/out, but need to be selected in tv setup menu.

and some tv even has a separate volume control for headphone output.

need to read your tv manual.

same problem here!

Got myself a Samsung 32C6200 recently (link) and i have a 2.1 creative I-Trigue L3800 speaker (link)

sound quality via headphone jack is really lousy and soft.

got
  • HDMI
  • PC/DVI audio in
  • component
  • audio/video
  • scart cable
  • digital audio out (optical)
  • headphone (only one working but bad quality)

Any advise on how use my speaker (3.5mm) with the tv??

no, the headphone jack is not meant for external speakers because the power output is very small.

You can only connect to external means via toslink (optical). Usually only surround receiver/amps have optical input/output for this purpose.

is there such a thing? I dun think so, the headphone jack is only meant for headphone/earphone as intended.

From the spec given by you, there is only an optical output which is the toslink which can only be connected to a AV amp/receiver then to your whatever speakers.

did some research seems like i'll need a DAC (correct me if im wrong), but DAC like very expensive leh, any recommendation for DAC that's affordable ( < $100) ? If more than $100 i'll rather go get a speaker or soundbar.

I dunno about DAC (convert digital output to analog) but another alternative is to buy those cheaper HTB (home theater out of the box) which accepts toslink connection. Probably cost few hundreds but you get better surround sound.

Another point to take note: nowadays many TV programs produce Dolby Surround sound so its best to hook up a Dolby Surround receiver/amp and 5.1 speakers because your LED/LCD optical output is capable of transmitting the sound channel. If you managed to hook up your 2.1 creative I-Trigue L3800 speaker then it is just normal stereo.

Think most probably will have to go get HTB =( another hole in my pocket...

Sorry to hijack this thread guys. But just to ask a question. I got a Panasonic SC-PT875 as a gift 2 years ago. Only got around to unboxing it recently. Set it up and routed the audio from my TV to the speakers but it came out at a really really very small volume. I maxed out the speakers' volume and it's still softer than if i had played sound straight out from my TV. I skipped connecting the microphone that came along with the set, is that what is causing the problem? Or am I using wrong cables or something? any advice?
