Question: where do you plug in extra speakers?  I have a set of PC speakers I would like to use
Document: Like others have said, the product is very nice. But the sound is marginal. I hooked up two little PC speakers and now the sound is fine.
We really like this TV and it suits our needs very nicely. We did end up ordering extra speakers because the sound, even turned all the way up is quiet and barely audible. It was easy to mount and will be enjoyed for a long time I hope.
I found the Jazz setting best for removing excess treble. But if that doesn't float your boat you can always plug in a set of external speakers.A little research told me the Sceptre uses the same remote programming codes as Sony TV's. However, since Sony doesn't make a TV/DVD combo, you're kind of out of luck with programming the DVD functions.
When the input source is cable, (in my case AT&T; Uverse), the volume is horrible. I selected the jazz setting for a full bass sound, but the volume was still low at the 100 setting. I attached PC speakers after I received an answer from a reviewer on where to plug them in. This made a lot of difference in the volumn when using cable as the source.I haven't used the DVD fuction yet.
The sound quality was out of the 1960's. I had to buy a set of small speakers to use with the TV in order to hear it at all. Very tinny sound. Shockingly poor sound.
I got this for an extra tv for my office. It works great! Plug it in and off you go. Thank you
I bought this Sceptre 19" LED HDTV with DVD for my elderly mother. We think it is really great! The picture is fantastic and the DVD player is simple to use. About the only complaint would be the 2 3-watt speakers aren't the greatest. But, what do you expect from a small inexpensive tv? There are 3 HDMI ports and a 3mm output for headphones or a better speaker system. I only paid $129 online from Walmart. No complaints here.
Let me start my stating: I am no audiophile. Friends would routinely make fun of my mix tapes in the 80s, which I taped off the radio and thought they sounded fine. Yet even I cannot bear the sound quality of this TV. After every adjustment possible (short of adding speakers, which would have been far too cluttered for kitchen-counter use), it still has sound quality that is actually more irritating than my daughter's plastic toy CD player.
This is a great little TV. I bought it for the kitchen for when I've got a lot of work to do in there. The only problem is the volume doesn't go up very loud. Easy remedy:  go to the store and get a cheap pair of powered (plugs into the wall) computer speakers (mine cost less than $15), and plug them into the headphone jack. They work great!
I love it easy to set-up, perfect size and very attractive. The sound is excellent, since my  6.5 years old like to blast the TV.
Answer: There is an Audio In jack on the back  (right side as viewed from the front), adjacent to the power cable plug.  There are also RCA Right/Left Audio jacks on the back of the monitor (left side as viewed from the front).
