Question: Does the AX510 sound bar plug into the monitor for power? Or does it have a power cord to an electrical outlet?
Document: Works well with the Dell u2412m monitor. Sound is average - but that is what one would expect from such a small soundbar - still seems better than the internal speakers of most laptops. Note - the u2412m actually has an area to plug in the bar - you don't need the power adapter that some reviewers have stated is necessary - don't know about other Dell Monitors. Overall - for the money - not a bad product - just don't expect exceptional sound.
This sound bar snapped right onto my Dell monitor and even gets its power from the monitor. It provides great sound for a good price. Very satisfied.
How many brand of monitors let you add speakers to it? This dell speaker bar was made perfectly fit the dell monitor and the cable attaches to monitor for power. You have a volume control and headphones out. Sound quality is good enough (better than many laptops).
There are two headphone outputs on the side. If you plug into either one you get sound from the headset but not from the sound bar. I'd love it if one of those didn't shut off the audio from the sound bar itself; I'd use it to drive the 2nd sound bar and eliminate the need for a splitter & a 2nd wire back to the computer.2.
I use these with my Dell monitor and they give a surprisingly good quality sound. It has an adjustment for volume as well as inputs for headphones. There is an led in the middle of the grill to indicate power which is unobtrusive. The unit powers down automatically when the monitor goes to sleep, a nice feature.
Good sound, not &#34;room filling&#34; but not tinny either. LED light power indicator is great, subtle but you know when it's NOT on and why Pandora is so quiet today. I love how it was designed to be integrated into the monitor - power and sound plugs are on the back of the monitor, not the computer, so no extra wires to wrangle. That's solid design right there.
The sound bar fit perfectly and hook up was very easy. recommended for someone needing a sound bar on their monitor
The sound bar is easy to install and and works instantly. The monitor powers it directly so no need for extra chargers. My only issue is the sound. It got room for much better speakers inside. Cost was good and I don't have a cluttered desk with external speakers. So its OK.
The sound quality of this sound bar is really poor, especially with vocals. Voices sound muffled, as if you're listening through a thin wall. If you like to watch movies or listen to music on your computer, you'll want something better.It's a shame, because I love how this attaches to the monitor and doesn't take any space on the desktop. It looks great if you just want to hear computer beeps and such.
I got electrical hum when I plugged into my computer. Dell was entirely annoying and of no help whatsoever in trying to resolve the issue. The experience makes me extremely reluctant to buy their products in future.
Answer: Depends on your monitor, the newer monitors have a power plug, if it is an older monitor then you would have to purchase a power supply seperately.
